Resumen
Stable biocompatible microparticles for immobilization of enzymes and their use in amperometric biosensors. Microparticles of the biocompatible hydrogel p-polyethylene glycol methyl ether methacrylate (pegmem) are used as an enzymatic immobilization system for their application as biological material in the design of an amperometric biosensor. The microparticles are immobilized on the surface of a platinum electrode by a dialysis membrane. The enzyme thus immobilized maintains its constant activity for long periods of time, allowing its use as a biological material for the preparation of amperometric biosensors, which maintain their enzymatic activity constant for at least 18 months.
