Definitions
- the present disclosure relates generally to systems, apparatuses, processes, and methods for delivering macromolecules or other materials into cells. Particular implementations leverage precise motion control and faithful integration and interfacing of system components to create a system for precise intracellular cargo delivery.
- Cell engineering is a promising area for scientific research and medical treatment development with numerous potential applications in medicine, biology, pharmacology, plant science, and other fields.
- a goal may be changing a cell’s functionality, internal chemistry, or genetic material by introducing new matter into the cell.
- Mammalian cells are particularly difficult to transfect with high efficiency, viability, and recovery due to their fragility and aseptic handling requirements.
- Current cell engineering solutions include chemical methods (e.g., lipofection, calcium phosphate precipitation), viral methods (e.g., retroviral, lentiviral, adenoviral vectors), and other physical methods (e.g., electroporation, microinjection, gene gun, or impalef ection).
- open arrays e.g., an array containing nanoneedles and an array containing a porous membrane
- Such alignment and/or planarization is difficult to achieve at the tolerances necessary at a nanometer scale.
- An added difficulty is operating the arrays in a system that optimizes footprint while integrating access to liquid handling, sensors, and biosafety controls.

- This disclosure describes systems, apparatuses, and methods for performing cell therapies and/or cell engineering with high precision. It is desirable in some cell engineering workflows to be able to insert a cargo (e.g., a chemical, mechanical, or genetic material) precisely into a single cell using microneedles.
- a cargo e.g., a chemical, mechanical, or genetic material
- References made in this disclosure to microneedles, microneedle structures, or microneedle chips are intended to also refer respectively to, for example, nanoneedles, nanoneedle structures, and nanoneedle chips.
- references made in this disclosure to nanoneedles, nanoneedle structures, and nanoneedle chips are intended to also refer respectively to, for example, microneedles, microneedle structures, or microneedle chips.
- needle chips can include, for example, microneedle chips and/or nanoneedle chips.
- single cells may be trapped at target locations on a cell trapping chip and then microneedles on a microneedle chip may be brought precisely into contact with the cells at the target locations.
- An example of trapping cells at a target location may include trapping cells at target locations in a porous membrane.
- Another example of trapping cells at a target location may include trapping cells in pores in a cell trapping chip.
- Another example may include both a porous membrane and a cell trapping chip used in combination. Other examples of trapping cells at target locations may also be possible.
- Unaligned contact between the target locations and needles can cause damage or failure of the needles, the cell trapping chip, or both.
- alignment in this context is very difficult.
- the dimensions of target locations (e.g., pores on a cell trapping chip) and of the microneedles on a microneedle chip can be made in such small scales that there is little room for error in aligning the target locations with the microneedles. This can be especially true because of the high aspect ratio to many microneedle structures (e.g., microneedles can be several times taller than they are wide) — if there is even a slight a discrepancy in planar alignment between cell trapping chips and microneedle chips, the needles may miss the cell target locations.
- the needles are fragile and cannot withstand contact with non-cellular materials (e.g., with other structures). Cell trapping chips may also be fragile. This fragility means that contact alignment is typically not a viable option for aligning the chips.
- the microneedle chips and the cell trapping chips are optically aligned such that the chips are co-planarized, or brought into a substantially parallel plane, to within 1 pm of error in four edges.
- Systems and modules used to handle and bring the chips into alignment may require similar precision tolerances.
- a system may execute cell engineering workflows by bringing cells onto a cell trapping chip having a plurality of cell traps, aligning the cell trapping chip with a microneedle or nanoneedle chip having a plurality of microneedles or nanoneedles such that each cell trap of the cell trapping chip is aligned with a single microneedle on the microneedle chip, and causing the chips to come into contact such that materials can be transferred into the cells from the microneedles.

- applying a vacuum to the cell trapping chip may form a microfluidic channel between the microneedle chip and the cell trapping chip.
- the vacuum may be applied when the needle chip reaches a preset height above the pores on the cell trapping chip.
- the vacuum may be a hydraulic pressure difference in the fluid between one side of the cell trapping chip and the other side.
- a low magnification microscope may scan over the cell trapping chip to determine the cell trapping efficiency.
- the user will input the desired poking parameters (e.g., approaching velocity, insertion distance, and/or needle in-cytoplasm duration).

If the cycle of the cell engineering process is complete, then at operation 843 cells may be collected. Collecting cells may include flowing the cells out of the cassette. This may be done, for example, using a syringe. Collecting cells may be alternatively performed by a pumping system. The cells may then be collected into a container.
- poked and unpoked cells may be flowed into respective dedicated output reservoirs (e.g., chambers or cavities) in the fluidics cartridge such that at the end of the poking operation, users can retrieve cells from those reservoirs.
- a fluidics cartridge may be used for multiple operations (e.g., multiple batches of the same cell engineering process). It may be desirable in such circumstances to have cell samples stored in a reservoir so they may all be retrieved at one time.
- a determination 844 may include determining whether a new cycle is to be performed. If a new cycle is to be performed, then the cell unloading process 840 may end and the new cycle may be started from operation 823 of FIG. 9B. In that case, in various instances, time to install a new cassette may be provided. If, at determination 841 of FIG. 9D, a new cycle is not to be performed, then at operation 845 the cell engineering process may completed, and a shutdown procedure may be initiated.

- a determination 846 may be made as to whether to reuse the needle chip. If the needle chip is to be reused, then a determination 847 may be made as to whether to collect cells. In various implementations it may be inefficient to collect all the cells each time the process is run, and so cell collection may be preferably delayed. If cells are to be collected, then at operation 848 the cells may be collected. Operation 848 may be functionally equivalent to operation 843 described above. After the cells are collected at operation 848, or if the determination 847 cells were not to be collected, then at operation 849 the old needle chip may be returned to the location it was retrieved from. The cell unloading process 840 would then end, and needle chip loading process 810 of FIG. 9A may be rejoined at operation 817, where a new needle chip would be selected.
- a determination 850 may be made as to whether to collect cells. If cells are to be collected, then at operation 851 the cells may be collected. Operation 851 may be functionally equivalent to operation 843 described above.
- a determination 852 may be made as to whether the needle chip is to be cleaned. If the needle chip is to be cleaned, then the process flows to operation 853.

- FIGs. 11A-11D illustrate an example of aspects of the needle chip loading process 810 and the cell loading process 820 as applied to a system in accordance with various implementations, including, for example, system 100.
- a user may load a cassette 710 into the cassette socket 514 on the platform 510.
- the cassette 710 may be secured in place with securing member 518 and fastened in place with fastener 519.
- FIG. 11A may include or correspond to operation 824 of cell loading process 820.
- the cassette 710 may be primed with fluids, including, for example, any number of a cell sample culture, a buffer, and/or a reagent. This may occur before the cassette 710 is loaded onto the platform 510, or after the cassette is loaded onto the platform 510.
- the hopper 320 loaded with needle chip holders 310 may be loaded onto the hopper rest 330 on platform 510. This may include or correspond to operation 815 of needle chip loading process 810 described above with reference to FIG. 9A.
- the hopper 320 may be installed such that the needle chip holders 310 are located at predefined known positions.

When the positions of the needle chips have been determined, the robotic gripper 340 may move to the needle chip position and picks it up as shown in FIG. 11B. This process may include or correspond to operation 817 of needle chip loading process 810.

- the robotic gripper 340 gripping the needle chip holder 310 may be moved using the gantry stage module 400 (can also be referred to as a gantry module) to a first aperture 512 in the platform 510.
- the system may estimate the rough location of the needle chip using the low magnification microscope (e.g., low magnification microscope 640 of FIG. 6A) and a focus algorithm, such as a predictive focus algorithm.
- the system may also determine the precise focus plane of the needle chip and the cell trapping chip 718 using the high magnification microscope (e.g., high magnification microscope 650 of FIG. 6A).
- an image processing routine may be used to determine the precise location of the needle chip and cell trapping chip 718.
- the gantry stage module 400 and the tip-tilt platform module 500 may adjust the positions of the needle chip and the cell trapping chip 718 to bring them into the same or a substantially parallel plane.
- the system may move the needle chip into the cassette 710 through opening 716 and into contact with the cell trapping chip 718.
- FIGs. 11A-11D may be performed by users or by automated systems. Any indication of whether a process is performed by a user or an automated system is included as an example and is not intended to limit the manner in which a process may be performed.
- An alignment process for a cell engineering workflow may include estimating the coordinates of features of a needle chip, estimating the coordinates of features of a cell trapping chip, and based on the estimated coordinates of the features of the needle chip and the estimated coordinates of the features of the cell trapping chip, moving at least one of the needle chip and the cell trapping chip into alignment with the other chip. After the alignment process is complete, the needle chip and the cell trapping chip will have surfaces aligned into the same plane.
- the chips to be aligned may be a microneedle chip and a cell trapping chip.
- the needle trapping chip may be formed with the same pitch of features and the same alignment fiducials as the needle chip. Chips formed in this manner can enable the use of optical alignment systems and robotics to align every nanoneedle to every cell trap.
- the chips may be co-planarized to within 1 pm of error in four edges. In order to ensure every nanoneedle on the needle chip pokes into a single cell at a target location (e.g in pores) in the cell trapping chip, careful alignment is required. However, the nanoneedles on the chips may be fragile, and thus cannot afford to perform contact alignment. Cell trapping chips may also be too fragile for contact alignment.
- Chips designed for contact alignment would need a more complex mechanical design to protect the nanoneedles. Instead, alignments may be made using a microscope to locate key features of the chips in three-dimensional space and a tip-tilt platform to move one of the chips into alignment with the other chips as described below. Alignments made using a tip-tilt platform may be confirmed optically before cell engineering processes on the chips are begun. In various implementations, at least one of the cell trapping chip and the needle chip may be formed of a transparent material. This may facilitate effective alignment between the chips.
- FIGs. 12A to 12C show a diagram of an example alignment process according to aspects of the present disclosure.
- FIGs. 12A-12C include illustrations of stages of an alignment process 1200.
- a high magnification microscope 1220 estimates the coordinates of key features of the needle chip 1210 using a sample of data points.
- the key features may include, for example, a first edge 1212 of the needle chip 1210, a second edge 1214 of the needle chip 1210, corners of the needle chip 1210, and/or fiducial marks located on the needle chip 1210.
- the coordinates of key features may first be roughly estimated by a low magnification microscope (not shown).
- a high magnification microscope 1220 can provide a narrow field of view. Using a low magnification microscope in a first stage can provide a wider field of view for an initial coordinate estimate.
- the coordinate estimate may correspond to the position of three of the edges of the needle chip. Identifying, estimating, and/or locating the unique coordinates of three key features of the needle chip 1210 may define a plane in which the needle chip 1210 is located. In various implementations, the coordinate estimate may correspond to the location of fiducial marks. Such fiducial marks may be located at the edge of the needle chip 1210. Again, the coordinates of at least 3 fiducial marks may be needed to define the plane of the needle chip 1210.
- the coordinates may correspond to a coordinate vector in three dimensional space.
- coordinates may be estimated with reference to a cartesian coordinate system (e.g., X, Y, and Z coordinates). Additionally or alternatively, the coordinates may be estimated with reference to angles of rotation. For example, in FIG. 12A the coordinates of an edge 1212 of the needle chip 1210 are suggested by reference to an offset Az, an x plane, and an angle 9 between the needle chip 1210 and the x plane.
- the coordinate information may be stored, for example in a computer memory, for use in alignment algorithms as described with respect to FIG. 12C below.
- the alignment process may use a microscope to accurately focus on fiducial marks that may be located at the corners of the needle chip and cell trapping chip.
- a predictive focus algorithm may be used to help locate a focus plane of the chip. Examples of a predictive focus algorithm will be discussed in further detail below.
- Identifying, estimating, and/or locating the unique coordinates of three key features of the needle chip 1210 may define a plane in which the needle chip 1210 is located.
- the coordinates of one of the key features of the needle chip 1210 are estimated, the coordinates of at least two other separate key features of the needle chip 1210 may be estimated in a similar manner.
- the coordinates of a first fiducial on a first corner (e.g., the top-left comer) of the needle chip 1210 may be determined and subsequently recorded.
- the coordinates of a second fiducial on a second comer e.g., the top-right comer
- a third fiducial on a third corner (e.g., the bottom-right corner) of the needle chip 1210 may be determined and subsequently recorded.
- This example is intended to be illustrative and not limiting, and it is anticipated that any of several alternate key features or locations on a needle chip may be used to identify the a plane in which the needle chip may be located, just as any of several alternative orders in which a needle chip’s key features are located may be used.
- the microscope 1220 may be used to estimate the coordinates of the key features of the cell trapping chip 1240. This may be done in a similar manner to estimating the coordinates of key features of the needle chip 1210.
- the coordinates of key features of the cell trapping chip 1240 may be estimated using a high magnification microscope 1220 or multiple microscopes (e.g. a low magnification microscope and high magnification microscope 1220). The coordinates may be defined using the same coordinate system as used for key features of the needle chip 1210 for ease of comparing the coordinates of the cell trapping chip 1240 to the coordinates of the needle chip 1210.
- the estimated coordinates of three separate key features of the cell trapping chip 1240 may be estimated in a similar manner to the three separate key features of the needle chip 1210.
- the three key features of the cell trapping chip 1240 may correspond to the three key features of the needle chip.
- FIG. 12C illustrates an example of aligning the cell trapping chip 1240 into planar alignment with needle chip 1210 by adjusting the angle of cell trapping chip 1240.
- estimating and/or locating the unique coordinates of three key features of the needle chip 1210 may define a plane in which the needle chip 1210 is located.
- Estimating and/or locating the unique coordinates of three key features of the cell trapping chip 1240 may define a plane in which the cell trapping chip 1240 is located.
- Alignment processes as discussed here in reference to stage c) may function to bring the cell trapping chip 1240 into the same plane as the needle chip 1210.
- an alignment algorithm may be used to compute the necessary movement parameters to align the chips based on the estimated coordinates of the needle chip 1210 and the cell trapping chip 1240.
- the computed movement parameters may correspond to an offset between the coordinate vectors of the needle chip 1210 and the corresponding coordinate vectors of the cell trapping chip 1240.
- the coordinate vectors from the key features on each of the chips may form a pair of coordinate vectors.
- the correction angles needed may be computed. These corrections may then be converted to the position of motorized stages of a tip-tilt platform.
- a tiptilt platform may be used to move at least one of the cell trapping chip 1240 and the needle chip 1210 into a calculated orientation such that the chips are aligned into the same plane.
- the goal of the alignment process is to manipulate the needle chip so that the separation distance between at least three corners of the cell trapping chip 1240 and at least three corresponding corners of the needle chip 1210 is the same. If the separation distance is the same between the corresponding comers of the chips is the same for each corner, that implies that the chips are planarized.
- needle chips and cell trapping chips may be aligned using an alignment algorithm.
- the alignment algorithm may include steps of identifying the coordinates of key features of a needle chip, identifying the coordinates of key features of a cell trapping chip, determining the plane in which the needle chip is positioned, determining the plane in which the cell trapping chip is positioned, determining a misalignment between the plane of the cell trapping chip and the plane of the needle chip, calculating the movement of one of the chips to bring the chip into the plane of the other chip, and moving the chip into alignment.
- a needle chip or a cell trapping chip may be disposed on a tip-tilt platform (e.g., an alignment module).
- the chip that is not disposed on the tip tilt-platform may be held in a fixed position relative to the other chip.
- a tip-tilt platform may include pushers (e.g., linear stages).
- the pushers may be arranged at comers of the tip-tilt platform.
- the pushers may include motors.
- the motors may be connected to a controller. The controller may be configured to run the motors and extend and/or retract the pushers.
- Extending and/or retracting the pushers may move the tip-tilt platform and/or alter its pitch and/or roll angle relative to the fixed position of the other chip.
- the controller may be configured using a transformation.
- the transformation may translate a calculated plane of alignment into a calculated set of pusher positions. Moving the pushers to the calculated set of pusher positions may bring the chip on the tip-tilt platform into the calculated plane of alignment.
- a microscope with a high magnification objective lens may be used to focus on fiducial markings on both the microneedle chip and the cell-trapping chip.
- a high magnification microscope can desirably create a shallow depth of field to determine the accurate focus plane.
- a high magnification microscope gives a narrow field of view. But the narrow field of view can be mitigated by the following exemplary predictive focus algorithm.
- the predictive focus algorithm may have 4 stages: image acquisition, image analysis, optimal focus determination, and focus adjustment. The stages are described below. [0135] (1) Image acquisition.
- the high magnification microscope captures a series of images at different focal planes (or Z-positions) within a predefined range above and below an initial focal plane.
- the range of focal planes will contain the focal plane at which the chip (either the microneedle chip or the cell-trapping chip) is located.
- the images may be analyzed to determine the sharpness and/or contrast within each image.
- Several methods can be used to analyze image sharpness, such as, for example, calculating the variance, sum-modified Laplacian, or Tenengrad function of the image.
- the microscope's hardware components such as, for example a motorized stage or a focusing mechanism, moves the objective lens or the stage to the optimal focal plane as determined by the algorithm.
- the predictive focus algorithm may be configured to focus its image analysis on the key features of the needle chip 1210 or the cell trapping chip 1240.
- Alignment processes such as those described herein may enable precision automation of cell engineering workflows.
- Precision automation may provide several benefits to cell engineering workflows and applications. For example, at least the following benefits may be achieved.
- Consistency and reproducibility Automated systems can precisely follow predefined protocols, ensuring consistent results with minimal variability. This leads to improved reproducibility.
- Increased throughput Automation allows for the simultaneous handling of multiple samples, increasing the overall throughput and efficiency of the process. This may be particularly valuable when working with large sample numbers or high-throughput screening applications.
- Reduced human error Automated systems minimize the risk of human error, such as pipetting mistakes or inconsistencies in handling, which can compromise the quality of the transfection process and the subsequent data.
- Enhanced safety Some transfection methods involve the use of hazardous materials or biohazardous samples. Automated systems can reduce the risk of exposure to these materials, ensuring a safer working environment.
