It is necessary to develop interfacing compounds for immobilizing the bioprobes, including an antibody, aptamer, natural receptors and so on, on the platform of biosensors which are consisted of 2D nanostructure. There are various 2D nanomaterials in the literatures. In particular, a graphene has high-conductivity, so the graphene-integrated biosensors have been constructed to enhance their sensitivity and selectivity. However, the surface of the graphene is highly stable owing to their non-covalent electron pairs, so that their surface modification is challenge. In this study, we demonstrated a new technology for graphene interfacing technologies. The new compounds can be easily attached on the graphene surface and the receptor-conjugated graphene FET showed high sensitivity and selectivity toward biocides, odorants, and decomposition. |
