- 1. Biophysics is an interdisciplinary field that combines principles of physics and biology to study the behavior of biological systems at the molecular, cellular, and organism level. This field aims to understand how physical forces and processes influence biological structures and functions, such as the mechanics of DNA replication, the flow of ions across cell membranes, and the electrical signaling in the brain. By using quantitative and computational techniques, biophysicists investigate the complex interactions between biological molecules and their environments to unravel the underlying mechanisms of life processes. Through the application of physics theories, tools, and methods, biophysics plays a crucial role in advancing our understanding of biological phenomena and developing innovative solutions for various biomedical and biotechnological challenges.
