Details
Organic Chemistry, Green Chemistry, Protein Chemistry, and Drug designing
Current Research — Molecular Engineering — We design and synthesize novel materials, and investigate how their properties connect with their molecular structures. We study non-covalent interactions to understand the properties of the molecules, their mechanism of action during interactions with biomacromolecules, and their self-assembly. Our research focus is synthesis, but many other types of experiments like solid-state physics, material science, biological testing, etc, also perform to explore different types of applications. We also investigate conformational, configurational, electronic, and molecular recognition effects of the synthesized molecules with the help of spectroscopic, crystallographic, and computational techniques through collaboration with physical chemists, inorganic chemists, biologists, and physicists. — Fundamental research on the non-covalent intermolecular interactions — We study the thermodynamic properties of non-covalent interactions formed during the association of small molecules with natural and synthetic supramolecules, quantitatively through systematic experiments (New J. Chem., 2018, 42, 14914-14925, Langmuir, 2019, 86, 11579–11589. ). Such investigations enrich the fundamental knowledge of non-covalent chemistry for understanding of the key factors control the properties and the function of a complex systems . This kind of knowledge has deep impact to design new molecules with precise and diverse applications.
