Nano Science and Technology
Our research focuses on understanding the chemistry of “atomically precise metal nanoclusters (NCs)” where 'every atom matters'. These NCs are composed of precise numbers of metals and ligands and they behave like molecules. The Group is also deeply involved in engineering nanoparticle (NP) surfaces for improved physico-chemical properties. We mentioned briefly some of our specific research directions in the following section.
Chemistry of Atomically Precise Metal Nanoclusters
Fundamentals of synthesis, the origin of physicochemical properties, molecular surgery, surface functionalization, and structure-property correlations.
Nanoscale Dynamics
Understanding the dynamics of intra and inter nanocluster structural and physical changes, nanocluster-small molecule interactions, nanoscale reactions etc. by means of spectroscopy and mass spectrometry.
Precise Engineering of Hybrid Materials
Synthesis, In-situ and ex-situ spectroscopic and microscopic investigation of physical properties of hybrid materials, reaction dynamics and applications
Nano-bio Interfacial Chemistry
The sustainable approach in NPs, spectroscopic analysis of their interaction with biological systems, understanding the bio-degradation pathway, enzymatic degradations, and bio-mimicking.
Molecular Material-Based Devices
Transforming colloidal molecular materials to cluster-solids via thin films and self-assembly; development of molecular material-based devices for chemical & biological sensing, electrochemical sensing, transport properties, disease identifications, etc.
