# Biophysics Cheatsheet ## Basic Concepts - Biophysics is the study of the physical principles that govern biological systems. - Biophysics is an interdisciplinary field that combines physics, biology, and chemistry. - Biophysics research can involve the study of molecules, cells, tissues, and organisms. ## Biomolecules - Biomolecules are molecules that are essential to life, including proteins, nucleic acids, carbohydrates, and lipids. - The structure and function of biomolecules can be studied using techniques such as X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy. - Computational methods, such as molecular dynamics simulations, can be used to study the behavior of biomolecules. ## Cellular Biophysics - Cellular biophysics is the study of the physical properties of cells, including their shape, mechanics, and electrical properties. - Techniques such as atomic force microscopy (AFM) and micropipette aspiration can be used to measure the mechanical properties of cells. - Patch clamp electrophysiology can be used to measure the electrical properties of cells. ## Biomechanics - Biomechanics is the study of the mechanical properties of biological systems, including bones, muscles, and tissues. - Biomechanics research can involve the study of movement, injury, and disease. - Biomechanical models can be used to simulate the behavior of biological systems. ## Medical Physics - Medical physics is the application of physics to medicine, including the use of radiation in diagnosis and treatment. - Medical physics research can involve the development of imaging techniques, such as X-ray, computed tomography (CT), and magnetic resonance imaging (MRI). - Radiation therapy is a common medical application of physics, where high-energy radiation is used to treat cancer. ## Neuroscience - Neuroscience is the study of the nervous system, including the brain, spinal cord, and nerves. - Neurobiophysics is a subfield of biophysics that focuses on the physical principles that govern the behavior of neurons and neural networks. - Techniques such as electrophysiology and functional magnetic resonance imaging (fMRI) can be used to study the activity of the brain. ## Resources - [Biophysics on Wikipedia](https://en.wikipedia.org/wiki/Biophysics) - [Biophysics: Searching for Principles by William Bialek](https://press.princeton.edu/books/paperback/9780691140667/biophysics) - [Biophysical Journal](https://www.cell.com/biophysj/home) (journal)
