Construction
The invention relates the method of screening and fast screening systems minimally invasive and noninvasive to identify and quantify substances of biomedical interest, with immediate results for patients, easy to scan the mass of the population to improve health.
Lately there was a growing increase in mortality among patients suffering from diseases such as cancer, hepatitis B, tuberculosis, HIV, influenza (eg, A H1 N1), etc.. The possibility of detection of these diseases is related to the characteristic symptoms among patients. This is the moment when the chances of living are very low if not nonexistent. Cases of survival are considered miracles for illness such as cancer, HIV, given the fact that the development of biochemistry and medicine at this time does not allow finding a solution to cure patients. There are solutions for the determination of glucose [US6043492], early determination of pregnancy [US3278270], the determination of immunity by measuring the levels of antioxidants in the skin [US6205354], which are minimally invasive or noninvasive.
The technical problem which aims to solve the present invention is to achieve a mass screening system that allows people to identify and quantify substances of biomedical interest in biological fluids and tissues, using methods of screening and screening systems for minimally invasive or non-invasive, with results obtained in real-time.
The system includes sensors with characteristics superior to those presented in the previous patents, BI123101 - the proposed stochastic sensor for ascorbic acid determination based on porphyrins, having macro size, and an electrolyte (KCI) in the plastic body, and Bl 125050 - proposed a stochastic microsensor for diagnosing of cancer at the molecular level, a few drops of blood can be used before and/or after cancer has been installed in the body, and the patent application A01 120/2010 where the DOT sensor formed from a working electrode, a reference electrode and an auxiliary electrode (amperometric electrodes only and stochastic electrodes) that can make analysis of two or more analytes simultaneously, using different techniques such as potentiometric, amperometric, stochastic, optical, the method being correlated with the nature of the substance to be determined, the working electrode consisting of a simple or modified diamond paste with different chiral selectors such as inulin, phthalocyanine. A608/2010 patent application have been proposed a method and system for detection, identification and rapid quantitative evaluation of specific biomarkers in biological fluids that can perform medical tests by automatic detection of the biomarkers known by the system, automatic identification of particular elements of the electrical signal generated by the biomarker, indicating precisely the type of biomarker and performing a quantitative evaluation of biomarkers in the sample of fluid, resulting in relative concentration.

The system used for the generation of the analytical information consists of electrochemical and optical sensors with different sizes and shapes, and it can be used for measurements of biological fluids and/or tissues according to the analysis required by the physician or the patient, with the ability to make one measurement or multiple measurements. Electrochemical and optical sensors are composed of a matrix that can be paste, sol-gel, plastic, metal (eg gold, platinum, silver), and an electroactive or/and optical compound which is of biological or synthetic nature, depending on the particular nature and composition of biological substance - reviewed biomedical interest.
