Voltammetric Sensing of Caffeine in Food Sample Using Cu‐MOF and Graphene

Electroanalysis (2020)

A. Venkadesh J. Mathiyarasu Sivaprakasam Radhakrishnan

Abstract Cu‐MOF/graphene composite were obtained by solvothermal and electrochemical methods. The interaction and formation of Cu‐MOF/graphene (GE) composite was systematically studied with the support of various characterizations including X‐ray diffraction (XRD), field emission scanning electron microscopy (FE‐SEM) and cyclic voltammogram (CV). The Cu‐MOF/graphene composite coated glassy carbon (GC) electrode exhibited good catalytic performance towards the electro‐oxidation of caffeine in neutral condition. The modified electrode displayed good linear range (5 μM to 450 μM), sensitivity (0.710 μA μM −1 cm −2 ), detection limit (1.38 μM), selectivity, high stability and reproducibility. Finally, the fabricated electrode extended into successful detection of caffeine in tea and coffee samples with good recoveries.

Electrochemical Enzyme-free Sensing of Oxalic Acid Using an Amine-mediated Synthesis of CuS Nanosphere

Analytical Sciences (2020)

A. Venkadesh J. Mathiyarasu Sivaprakasam Radhakrishnan

Copper sulfide nanospheres (CuS NS) were prepared by a solvothermal method with the support of p-phenylene diamine as a structure direct agent. The formation of CuS NS was evaluated using XRD, FE-SEM, HR-TEM, XPS, and electrochemical methods. The CuS NS modified electrode demonstrated excellent electro-catalytic behavior for the electro-oxidation of oxalic acid (OA). The modified electrode showed a good linear range (50 to 700 μM), high sensitivity (0.0353 μA μM-1 cm-2), a low detection limit (35.6 μM), long term stability and good anti-interference behavior.

Paper Electrochemical Sensor Utilizing Nano Ag‐Decorated Cu2O Nanoparticles for Ascorbic acid Detection in Tablets

Analysis & Sensing (2025)

A. Venkadesh Anumol Mathew Thayyil K. Fahmeeda J. Sonia B. N. Kumara

The accurate and selective detection of vitamins are very much needed in the food, and pharmaceutical industries and health care. In this study, a new sustainable disposable electrochemical platform was fabricated with nano silver/Cu2O composite (nAg/Cu2O) for sensing ascorbic acid (vitamin C). The modified electrode exhibited reduced resistance to charge transfer and improved electro active area. The analyte displayed excellent electrochemical activity on the surface of nAg/Cu2O modified paper electrode and showed a concentration‐dependent response between 0.05 to 500 µM with a detection limit (S/N=3), 0.04 µM. Furthermore, the anti‐interference studies revealed that the nAg/Cu2O nanocomposites have high selectivity towards ascorbic acid. Notably, the sensor based on nAg/Cu2O showed exceptional stability and reproducibility, with a relative standard deviation for peak currents measuring approximately 7% or less while testing for a week of time. The real‐world application and analytical performance was realized by identifying ascorbic acid in commercial vitamin C tablets with satisfactory results.
