Current Research

Our group is actively involved in the fabrication of different types of chemical sensors , specifically electrochemical and optical sensors. Electrochemical sensors include potentiometric sensors, incorporating different types of ionophores – calixarenes, porphyrins, crown ethers, schiff bases, ion association complex etc are used for the determination of metal ions and drugs as well as voltammetric sensors for the analysis of drugs, food additives and biological molecules by modification of electrode surface using metalloporphyrins, conductind polymers, nanomaterials and self assembled monolayers. Currently the main focus of the group is on the development of fluorescence sensors and colorimetric sensors based on quantum dots, nanomaterials etc. for environmental, food and clinical monitoring. The group is also working in the field of immunosensors and biosensors.
