Carbon Nanotube Biosensors Based on Electrochemical Detection

The advantages of carbon nanotubes, such as high surface area, favorable electronic properties, and electrocatalytic effect, attracted considerable attention very recently for the construction of electrochemical biosensors. We describe here the construction and application of carbon nanotube/epoxy rigid polymer composite electrochemical biosensor for the detection of important biomarkers, such as NADH and hydrogen peroxide.
