The development stage readiness: Pre-production model is made

Description of the development:
()
The principle of operation is based on measuring the biochemical activity at the same time for a number of enzymes (acetyl and butirilholinesterazy, urease and glyukooksidazy) and the determination of residual enzyme activity when exposed to heavy metals or pesticides contained in the test solution. For the measurement of enzyme activity using an array of electrochemical sensors based on capacitive structures electrolyte-insulator-silicon with a pH-sensitive layer of silicon nitride. Functioning multienzimosensora occurs through measurement of high-frequency capacitance-voltage characteristics at the same time for each individual sensor array and calculation using them flat-band potential of the silicon surface as a signal sensor response.
