Abstract :
Gold-graphene (Au-G) nanocomposite has been synthesized by wet chemical method. Synthesized Au-G nanocomposite was examined under the UV-vis spectroscopy and transmission electron microscopy (TEM). Further Au-G nanocomposite was drop casted onto the glassy carbon electrode (GCE) by immobilizing glucose oxidase (GOx) into it for the electrochemical detection of glucose. Fabricated sensor demonstrates good linear response to glucose in the range 3 to 18 mM with linearity coefficient 0.964.
