Biophysics is a multidisciplinary field that applies principles of physics to understand biological systems at various levels, from molecules to organisms. It explores the physical properties of biological systems, such as the mechanics of cells and tissues, the structure and function of biomolecules, and the processes involved in biological functions like muscle contraction and nerve signaling. Biophysicists use a combination of experimental techniques, computational modeling, and theoretical approaches to study these complex systems and gain insights into fundamental biological processes. The goal of biophysics is to bridge the gap between the physical sciences and the life sciences, ultimately leading to a deeper understanding of living organisms and the development of new technologies and therapies.
