Abstract

The present invention is directed to methods for synthesis of solid objects such as nanoparticles in a microf luidic system. In addition the present invention provides a novel micro fluidic device for the formation and fusion of droplet pairs by means of hydrodynamic coupling of two spatially separated nozzles (104, 105). The device and methods of the present invention utilize the pre- compartmentalization of reagent solutions for increased control over the initiation and quenching of reactions as well as a means for capturing solid precipitates or other solid objects formed after the fusion of droplet pairs.
