Highly sensitive urine glucose detection with graphene field-effect transistors functionalized with electropolymerized nanofilms

Autor: Wolfgang Knoll, Omar Azzaroni, Waldemar A. Marmisollé, Gonzalo E. Fenoy

Publikováno v: Sensors & Diagnostics. 1:139-148

We introduce a new approach for glucose oxidase (GOx) immobilization on graphene field-effect transistors (gFETs) to fabricate highly sensitive glucose sensors. The strategy relies on the electropolymerization of a layer of the copolymer poly(3-amino
