▎ 摘　　要

Porphyrin covalently bonded to graphene oxide (Por-GO) was used as a photoactive unit, and resulted in an enhanced photoresponse, when in combination with gold nanoparticles (GNP) as a light harvesting unit, due to its plasmon resonance absorption effect. Photocurrent monitoring of the interaction between the surface-modified Por-GO with adenosine compounds was demonstrated.
