What is BIOPHYSICS? What does BIOPHYSICS mean? BIOPHYSICS definition – How to pronounce BIOPHYSICS



biophysics is an interdisciplinary science that applies the approaches and methods of physics to study biological systems biophysics covers all scales of biological organization from molecular to organismic and populations biophysical research shares significant overlap with biochemistry nanotechnology bioengineering computational biology and systems biology the term biophysics was originally introduced by Karl Pearson in 1892 molecular biophysics typically addresses biological questions similar to those in biochemistry and molecular biology but more quantitatively seeking to find the physical underpinnings of biomolecular phenomena scientists in this field conduct research concerned with understanding the interactions between the various systems of a cell including the interactions between DNA RNA and protein biosynthesis as well as how these interactions are regulated a great variety of techniques are used to answer these questions fluorescent imaging techniques as well as electron microscopy x-ray crystallography NMR spectroscopy atomic force microscopy Athan and small angle scattering SAS both with x-rays and neutrons says slash sends are often used to visualize structures of biological significance protein dynamics can be observed by Neutron spin eco spectroscopy conformational change in structure can be measured using techniques such as dual polarisation interferometry circular dichroism says and sounds direct manipulation of molecules using optical tweezers or eighth can also be used to monitor biological events where forces and distances are at the nanoscale Molecular biophysicists often consider complex biological events as systems of interacting entities which can be understood for example through statistical mechanics thermodynamics and chemical kinetics by drawing knowledge and experimental techniques from a wide variety of disciplines bio physicists are often able to directly observe model or even manipulate the structures and interactions of individual molecules or complexes of molecules in addition to traditional that is molecular and cellular biology or enzyme kinetics modern bio physics encompasses an extraordinarily broad range of research from bio electronics to quantum biology involving both experimental and theoretical tools it is becoming increasingly common for biophysicists to apply the models and experimental techniques derived from physics as well as mathematics and statistics see biomathematics to larger systems such as tissues organs populations and ecosystems biophysical models are used extensively in the study of electrical conduction in single neurons as well as neural circuit analysis in both tissue and whole brain generally biophysics does not have university level departments of its own but as presence as groups across departments within the fields of molecular biology biochemistry chemistry computer science mathematics medicine pharmacology physiology physics and neuroscience
