Electrochemical Biosensor for Evaluation of Contaminants in Food

Abstract
This paper describes the application of electrochemical disposable biosensors in food analysis, which have recently been developed in our laboratory. The disposable biosensors, based on acetylcholinesterase inhibition potential, were exploited for testing the presence of organophosphorus and carbamatepesticides in water, fruit, and vegetable samples. The paper further describes preliminary tests for the detection of genetically modified organisms and hybridisation by coupling the DNA biosensors with the polymerase chain reaction.
