Biophysical Chemistry is a specialized field that combines principles of biology, chemistry, and physics to understand the structure, function, and interactions of biological molecules. It involves the use of experimental and theoretical approaches to investigate the physical and chemical properties of biological macromolecules, such as proteins, nucleic acids, and lipids. Biophysical chemists study how these molecules interact with one another and their environment to carry out biological functions, and apply this knowledge to develop new drugs, materials, and technologies.
