Low electro-synthesis potentials improve permselectivity of polymerized natural phenols in biosensor applications
(
Elsevier
, 2017 , Article)
First-generation amperometric biosensors are often based on the electro-oxidation of oxidase-generated H2O2. At the applied potential used in most studies, other molecules such as ascorbic acid or dopamine can be oxidized. ...
