This work reports a new non enzymatic cholesterol detection sensor using functionalized nanographite. This nanostructure was characterized by FTIR, SEM, TEM, XRD and EDX. Using nanographite as a working electrode, Ag/Agcl as a reference and platinum as a counter electrode a good non enzymatic cholesterol sensor was constructed. Under optimal detection conditions, the constructed sensor had a linear range of 50 to 500 mg/dl for cholesterol with a correlation co-efficient of 0.99784. Sensitivity of the developed cholesterol sensor is 1.0587 μA/mg. This biosensor showed good reproducibility, stability and low interferences.
