Graphene electrode platform for impedimetric aptasensing

In this study, we synthesized graphene oxide (GO) at different oxidation times (30, 60 and 120 min) using a modified Hummer's method and investigated their carbon-to-oxygen (C/O) ratios, the % C-C double bond, the diffraction pattern, their topography and their electrochemical behaviour both by...
