摘要：

Thylakoid membranes isolated from spinach leaves were immobilized by entrapment in polyvinylalcohol bearing styrylpyridinium groups. The reduced species produced by photosynthetic membranes are oxidized at a platinum 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 respectively 2x10(-8) and 2x10(-7) M for diuron and atrazine.
