Photopolymerized redox hydrogel biosensors

摘要

We will demonstrate UV- photopolymerization as a viable method of fabrication for sensors capable of detecting galactose and lactate. Our previous work has shown that UV- photopolymerization can be used to create working glucose sensors utilizing ferrocene as a charge mediator and PEG as the polymer matrix backbone. We belive that galactose oxidase and lactate oxidase can, just as glucose oxidase was before, be entrapped in a redox polymer hydrogel while retaining activity and delivering constant current responses upon addition of galactose and lactate.
