Carbon materials have unique physical and chemical properties such as force, magnetism and electricity, especially graphene and carbon nanotubes. Nano gold is a kind of nano material with excellent biocompatibility. The biosensor constructed by compounding carbon materials with nano gold has the characteristics of high sensitivity and strong specificity. Therefore, the composite is widely used in various biosensors. In this paper, the applications of graphene/nano gold and carbon nanotube/nano gold in electrochemical biosensors were reviewed.
