Abstract

Nano-graphite oxide has been synthesized from graphite flakes using modified Hummer’s method. Fourier transform infrared (FT-IR) data, x-ray diffraction (XRD) and transmission electron microscopy (TEM) revealed functionalization of the synthesised nano-graphitic platelets with oxygenated bonds. Using thermal embedding technique for the fabrication of self-assembled films, electrodes of nano-graphite oxide have been fabricated for enzyme free detection of cholesterol electrochemically. The electrodes provided a linear response for the enzyme less detection in the range of 50mg/dl to 500mg/dl with a correlation coefficient, R, of 0.99784 and sensitivity of 1.0587 µA/mg.
