Biomembranes are thin, flexible layers of lipid molecules that surround cells and organelles within cells. These membranes play a crucial role in controlling the flow of substances in and out of cells, as well as in maintaining the overall structure and integrity of cells. Research in biomembranes focuses on understanding the composition, structure, and function of these membranes, as well as how they are involved in various cellular processes such as cell signaling, transport, and cell-cell interactions. This research area is interdisciplinary, incorporating concepts and techniques from biology, chemistry, and physics to study the complex interactions and dynamics of biomembranes.
