Photopolymers as an immobilized matrix in biosensing

Biosensors are perspective devices for analysis of substances in chemistry, biological chemistry, medicine, biotechnology and also for environment status monitoring. Their advantages are compact size, short time of analysis, display high response and simplicity in usage. The working characteristics of biosensors often depend on efficacy of a biological stuff immobilization on the surface of transducer. In this context there is a need for development of immobilization methods capable to provide for execution of the following demands: 1) compatibility of this process with technology of building transducer; 2) simplicity in fulfillment, cheapness and expressness at manufacture of biomembranes; 3) ability to provide the maximal safety of a biological stuff activity and its high adhesion to a surface of transducer; 4) reproducibility at serial application and capacity of standardizing. Usage of photocrosslinked and photopolymerized compound at the immobilization of a biological stuff allows to provide execution of the listed above demands. The present review is devoted to features of application of the given class of compound at building of biosensors.
