Biophysics: Meaning and Definition

Biophysics is the interdisciplinary study of biological processes using principles and methods from physics. It aims to understand how biological systems function at the molecular, cellular, and organismal levels by applying concepts like mechanics, thermodynamics, and quantum physics.

Definition:

Biophysics is the branch of science that applies the principles of physics to understand the structure, function, and dynamics of biological systems.

Key Areas of Biophysics:

1. Molecular Biophysics – Studies protein folding, DNA structure, and biomolecules.

2. Cellular Biophysics – Examines cell mechanics, transport, and membrane functions.

3. Neurobiophysics – Explores brain function, nerve signaling, and electrophysiology.

4. Medical Biophysics – Includes applications in MRI, CT scans, and radiation therapy.

Applications of Biophysics:

• Medical Imaging (X-rays, MRI, PET scans)

• Drug Discovery (Understanding protein-ligand interactions)

• Genetic Engineering (DNA manipulation and CRISPR technology)

• Bioinformatics (Molecular modeling and simulations)

What is Biophysics?

Meaning and Definition

Biophysics is the interdisciplinary science that uses the principles and methods of physics to study and explain the structure and function of biological systems.

Definition:

Biophysics is the scientific study of biological processes using the concepts and techniques of physics, such as force, energy, motion, and electromagnetism.

Key Features of Biophysics:

Feature	Description
Combines sciences	Physics + Biology + Chemistry + Mathematics
Uses physical methods	X-rays, MRI, spectroscopy, lasers
Studies microscopic systems	Cells, DNA, proteins, nerves, molecules

Examples of Biophysics Applications:

1. Studying how proteins fold and function

2. Understanding DNA structure through X-ray crystallography

3. Using MRI to view internal organs

4. Analyzing how nerves transmit signals

Why is Biophysics Important?

• Helps understand life at the molecular level

• Aids in medical technology development (e.g., CT scans, pacemakers)

• Supports drug discovery and diagnostics

• Explains physical forces inside living organisms

Etymology (Word Origin):

• Bio = Life

• Physics = Natural science of matter, energy, and forces

So, Biophysics = Physics of Life
