Abstract:
This work reports a novel strategy for the development of an O2-rich biosensor. The principle is based on an enzymatic reaction between catalase and H2O2 to release O2, thus to increase the O2 amount in the enzyme matrix. This method improves the determination reliability by alleviating the O2 dependence.
