dc.description.abstractRuthenium-based complexes demonstrate high potential in the catalysation of the electrochemical oxidation of glucose, offering high sensitivity and stability in glucose detection. In this study, a ruthenium complex (Ru1) was synthesised using 2,2′-bipyridine-4,4′-dicarboxylic acid (DCBpy), potassium iodide (KI) and [RuCl₂(p-cymene)]₂. The structural properties of Ru1 were investigated using X-ray diffraction (XRD), nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and UV–vis spectroscopy analyses, which revealed its structure. The electrochemical behaviour of the Ru1 complex was systematically investigated and found to be promising for application in a glucose biosensor. Cyclic voltammetry measurements revealed an increase in electrochemical activity on the electrode surface over time, showing a steady rise at a potential of 0.32 V. This indicates high sensitivity and reliability in glucose detection. Chronoamperometric analysis showed a linear response to glucose concentrations ranging from 0.1 to 0.8 mM, demonstrating the sensor's sensitivity. These properties make the Ru1 complex a promising candidate for use in glucose detection biosensors. In conclusion, the complex's electrocatalytic activity and stability could be key to advancing biosensor technologies by enhancing sensitivity.
