Our research group is advancing the understanding and control of atomically precise materials for life. Some of our specific research directions are mentioned in the following section.
Atomically Precise Metal Nanoclusters
Fundamentals of synthesis, the origin of physicochemical properties, molecular surgery, surface functionalization, emerging properties, 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. using spectroscopy and mass spectrometry.
Nanohybrids
Synthesis, In-situ and ex-situ spectroscopic and microscopic investigation of physical properties of hybrid materials, reaction dynamics and applications
Biomaterials
The sustainable approach in NPs, spectroscopic analysis of their interaction with biological systems, image-guided drug delivery, understanding the bio-degradation pathway, enzymatic degradations, and bio-mimicking.
Nanomaterial-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, energy, disease identifications, healthcare, etc.
