title: [Study on characteristic of biosensors associated with cholinesterase for detection of pesticide residues].
abstract: Current research activity in characteristic of biosensors associated with cholinesterase (ChE) for detection of organophosphate and carbamate pesticide residues is summarized. Some novel methods, which aimed to overcome the problems inherent to ChE inhibition analysis, namely selectivity, accuracy, irreversible inhibition and matrix effect, etc, are commented. More sensitive genetically engineered ChE variants and sophisticated parallel detection systems are also envisaged when it comes to turning biosensors based on ChE into marketable products, respectively.
