Abstract
Thylakoid membranes isolated from spinach leaves were immobilized by e ntrapment in polyvinylalcohol bearing styrylpyridinium groups. The red uced species produced by photosynthetic membranes are oxidized at a pl atinum working electrode in a microphotoelectrochemical cell. Free and entrapped thylakoids were compared for their responses to inhibition by two herbicides: diuron and atrazine. The detection limits were resp ectively 2x10(-8) and 2x10(-7) M for diuron and atrazine.
