Membrane biophysics is a field of study that focuses on the physical and chemical properties of biological membranes and the interactions between various molecules within these membranes. This area of research explores how membrane proteins, lipids, and other molecules function together to regulate biological processes such as cell signaling, protein transport, and cell-cell communication. Membrane biophysics also examines the structure and dynamics of membranes at a molecular level, using techniques such as spectroscopy, microscopy, and computational modeling to understand the complexity of membrane organization and function. Overall, membrane biophysics plays a critical role in advancing our understanding of fundamental biological processes and diseases.
