Immobilized Enzymes on Graphene as Nanobiocatalyst [PDF]
ACS Applied Materials & Interfaces, 2019 Using enzymes as bioelectrocatalysts is an important step toward the next level of biotechnology for energy production. In such biocatalysts, a sacrificial cofactor as an electron and proton source is needed. This is a great obstacle for upscaling, due to cofactor instability and product separation issues, which increase the costs.
