Enhancing the electrochemical measurement of drug molecules

This research project is focused on the preparation of several reduced graphene oxide based composites. Their physicochemical properties were successfully characterized by ultraviolet-visible spectrometry, Fourier transform infrared spectrometry, Raman spectroscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy. With large surface area and high electrocatalytic activity, the as-synthesized materials were then used as electrode modifiers to effectively improve the electrochemical signals in detection of targeted drugs such as carbendazim, ciprofloxacin and acetaminophen. The obtained results strongly suggest that the composites could be potentially employed to fabricate simple but sensitive sensors for the electrochemical determination of electroactive drugs in the future.
