This group focuses on the synthesis of metal/metal oxide nanoparticles/nanoclusters with a fair control over their size, shape and surface chemistry, their use as building blocks to develop new nanostructured materials with controlled nanoscale features and unique properties. These nanomaterials are also being evaluated to explore their potential applications in renewable energy technologies (solar/fuel cells and H2 production), catalysis, drug/gene delivery, disease diagnostics, sensing, bacterial detection and environmental remediation.
