Electrocatalytic activity of C-dots for highly sensitive detection of Uric acid

Abstract

Abstract Over the past decades, carbon based materials used as many applications, particularly, medicine, biosensors, catalysis and so on. The high potential C-dots (CDs) were synthesized via simple microwave irradiation method. As synthesized C-dots were characterized using many of the techniques, such as XRD, FT-IR, DRS UV vis spectroscopy. The CDs surface was analyzed using FESEM microscopy. Further the objective of the synthesized CDs was catalytic sensing of Uric Acid (UA). The CDs modified electrode gives better result than bare electrode. The electrochemical station comprises three electrode systems, calomel electrode as a reference electrode, platinum electrode as counter electrode and glassy carbon electrode (GCE) as a working electrode. The CDs modified electrode gives the sensing of 10-4M UA oxidation peak at 0.51 V at 50 mV scan rate using pH 7 buffer solution.
