| Abstract: | The present invention relates to a copper coumarin compound of Formula A [C20H20CuN4O(NO3)2] electrode for electrochemical sensing of homocysteine (Hcy) in carbonate-bicarbonate buffer at pH 10.2-10.8, even in the presence of higher concentration of other competing species such as cysteine, glutathione, ascorbic acid. The copper-coumarin electrodes based electrochemical sensor can be measure Hcy selectivity in serum sample even at a low concentration (1 ?M). The copper-coumarin electrodes based electrochemical sensor is suitable for measuring Hcy in real time analysis since no requirement of binding time and the electrode modification procedure is simple. The limit of detection and limit of quantification for Hcy is 0.025 ?M and 0.077 ?M with R2 square value 0.96. The peak current observed at the peak potential showed a linear increase in current with respect to Hcy concentrations. Other biothiols such as cysteine (Cys) and glutathione (GSH) did not produce any detectable signal at the peak potential observed for Hcy, indicating the selective nature of the electrosensor towards Hcy. |
