Bioresponsive, Electroactive, and Inkjet‐Printable Graphene‐Based Inks

With the advent of flexible electronics, old fashioned and conventional solid-state technology will be replaced by conductive inks combined with low-cost printing techniques. Graphene is an ideal candidate to produce inks, due its excellent conductivity zero bandgap. The possibility chemically modify graphene active molecules opens up field responsive inks. Herein, a bioresponsive, electroactive, inkjet-printable ink presented. based on modified selected enzymes electrochemical mediator, transduce products enzymatic reaction into electron flow, proportional analyte concentration. A water-based formulation engineered respectful activity while matching stringent requirements inkjet printing. efficient performance ink, as well proof-of-concept application in biosensing, demonstrated. versatility system demonstrated modifying various oxidoreductases, obtaining selectivity toward glucose, lactate, methanol, ethanol.
