Organophosphate Hydrolase in Conductometric Biosensor for the Detection of Organophosphate Pesticides [PDF]

open access: yesAnalytical Chemistry Insights, 2015
The research has developed an enzyme biosensor for the detection organophosphate pesticide residues. The biosensor consists of a pair of screen-printed carbon electrode (SPCEs). One of electrodes contains immobilized organophosphate hydrolase (OPH) on a chitosan membrane by cross-linking it with glutaraldehyde.
