what is biophysics??

Question

give me some basic idea abot biophysics. what it deals with??what is the application??

Answer 1

Biophysics
A hybrid science involving the overlap of physics, chemistry, and biology. A dominant aspect is the use of the ideas and methods of physics and chemistry to study and explain the structures of living organisms and the mechanisms of life processes. The recognition of biophysics as a separate field is relatively recent, having been brought about, in part, by the invention of physical tools such as the electron microscope, the ultracentrifuge, and the electronic amplifier, which greatly facilitate biophysical research. These tools are peculiarly adapted to the study of problems of great current importance to medicine, problems related to virus diseases, cancer, heart disease, and the like.

The major areas of biophysics are the following:

Molecular biophysics has to do with the study of large molecules and particles of comparable size which play important roles in biology. The most important physical tools for such research are the electron microscope, the ultracentrifuge, and the x-ray diffraction camera. See also Molecular biology; Ultracentrifuge; X-ray diffraction.

Radiation biophysics consists of the study of the response of organisms to ionizing radiations, such as alpha, beta, gamma, and x-rays, and to ultraviolet light. The biological responses are death of cells and tissues, if not of whole organisms, and mutation, either somatic or genetic.

Physiological biophysics, called by some classical biophysics, is concerned with the use of physical mechanisms to explain the behavior and the functioning of living organisms or parts of living organisms and with the response of living organisms to physical forces.

Mathematical and theoretical biophysics deals primarily with the attempt to explain the behavior of living organisms on the basis of mathematics and physical theory. Biological processes are being examined in terms of thermodynamics, hydrodynamics, and statistical mechanics. Mathematical models are being investigated to see how closely they simulate biological processes. See also Biomechanics; Biopotentials and ionic currents; Mathematical biology; Micromanipulation; Microscope; Muscle proteins; Muscular system; Oximetry; Skeletal system; Space biology.

Answer 2

Well being in university, here is what I have learned about biophysics...

Biophysics (or biological physics) is made up of a lot of different studies. As a course, you learn about things like the creation and use of mechanical limbs, or how machines can be used to regulate bodily functions. (pacemakers, etc) This is where biophysics and bioengenerring seem to blurr a little bit. I think it is helpful to remember that biophysics itself is realitvly new to the science scene in general.
Luigi Galvani (sorry, not sure on the spelling) is one of the more famous "biophysicists", it may help to look up on him and his work. (He discovered bioelectricity)
So its a bit difficult to pin down what exactly biophysics is, because it includes so may fields of study. I would describe it to adressing biological questions and apply those questions using the basics of physics.(questions like solving a protein structure, or measuring reaction rates in a single molecule.)

Anyways, hope that helps!

Answer 3

Biophysics is NOT the same as biological physics. Biophysicists don't make false legs!
