Abstract

This study proposes a novel way to design and fabricate a gaseous formaldehyde sensor based on self-assembled graphene. Layer-by-layer (LbL) method enables to functionalize graphene surface with formaldehyde dehydrogenase (FALDH) that works as a catalyst for specific enzymatic reaction of formaldehyde. The enzymatic reaction is triggered near by the graphene surface, so that graphene can quickly respond and sense formaldehyde. This fabrication method offers the possibility of use of graphene-based gas sensors in a broader spectrum.
