Our research focuses on detection technologies using nanomaterials for a range of analytes i.e. blood biomarkers, pathogens, pesticides and small molecules. The currently undergoing projects include Point of care detection of cardiac biomarker peptides using natural and synthetic receptors (aptamers) on nanostructured electrochemical based biochips. We also work on Purification and characterization of surface biomarkers to enable selective detection of water borne pathogens. We develop new kinds of optical and electrochemical immunoassays for pathogen detection in food and water samples. We synthesise different kinds of nanoparticles, nanoclusters, carriers, haptens, bioconjugates and work on biointerface development to enable low-cost diagnostics.
