Abstract

An optical biosensor has been developed for detection of pesticides, based on surface plasmon resonance (SPR) technique. Concentration of the pesticides was measured in liquid or gas. We specially originated organic film on a disposable element. A setup on the base of Kretschmann arrangement was improved by using a computer-controlled angular scanning system. The detection concentration limit of dinitrophenole (DNP) was 10^-9 M. Some samples exhibited effect down to 10^-11 M of DNP. The results obtained provide reason for further development of SPR sensor as applied to pesticides monitoring.
