Biosensors based on cholinesterases for the analysis of pesticides, heavy metal ions and hypochlorite species

A. P. Soldatkin

The enzyme biosensors based on cholinesterases and electrochemical transducers were developed for the analysis of pesticides, heavy metal ions and hypochlorite species in water solutions. Bioselective membranes on the transducers surface were formed by cross-linking of cholinesterases with bovine serum, albumin in saturated glu-taraldchyde vapour. Working characteristics of the biosensors deve¬loped were studied and optimized.
