Flexible Electroconductive Hydrogel for Biosensors and Biofuel Cells Application

Flexible electroconductive hydrogel shown as a promising material for enzyme and bacterial bioelectrochemical systems. For hydrogel synthesis biocompatible polymers PEDOT PSS, carrageenan and polyvinyl alcohol were used. It is shown the mechanical properties of hydrogel and provided an electronic microscopy investigation. The oxidation processes on the electrode with enzymes and bacterial cells are demonstrated. Chosen materials and methods of synthesis did not provide any nonbiocompatible substances in hydrogels. Thus, presented materials can be promising for flexible electrodes design for biocompatible applications.
