Abstract
Novel fiber-optic biosensors have been developed for the analysis of pesticides in water based on Chlorophyceae microalgae immobilized into a porous silicone layer as recognition element, and on measurements of the photogenerated O2 as chemical transducer. The inhibition of O2 production by the photosynthetic green algae in the presence of the pesticide (simazine) was used as the biological signal. Luminescent thin films and a dedicated optoelectronic unit based on emission phase-shift measurements provide the tools for the sensitive O2 measurements. Fluctuation analysis allows selection of sensitive and resistant microalgae mutants without genetic manipulation for maximum biosensing selectivity.
