Biophysical

Relating to both biological and physical aspects of a phenomenon, especially concerning the application of physical principles and techniques to the study of biological systems. It involves the investigation of biological processes at the molecular and cellular level, considering physical laws such as energy, matter, and forces. biophysical research often uses tools and methodologies from physics, chemistry, engineering, and mathematics to understand complex biological systems. This field bridges the gap between the biological and physical sciences, seeking to explain biological phenomena through the lens of physical laws and principles. Biophysics is often used to study cellular structures, molecular interactions, and physiological functions. It includes areas like biomechanics, molecular biophysics, and sensory biophysics.

Biophysical meaning with examples

• Understanding the biophysical properties of cell membranes, such as their elasticity and permeability, is crucial for comprehending cellular transport mechanisms. Scientists use atomic force microscopy to visualize membrane structures and analyze how various molecules interact with the membrane.
• Studying the biophysical effects of radiation on DNA helps us to understand how radiation damages cells, leading to mutations and potential health problems. Researchers use sophisticated techniques to quantify the energy absorption and the resulting chemical changes in the DNA structure.
• Investigating the biophysical interactions between proteins and other molecules allows researchers to understand how proteins function and regulate biological processes. Biophysicists employ X-ray crystallography to determine the structure and binding affinities of proteins.
• The study of biophysical aspects of muscle contraction helps us understand the forces involved in movement. This research uses techniques like optical tweezers to measure forces generated by muscle filaments, and the electrical stimulation of muscle fibres to examine the physiological response.
