Biophysicists observe and study chemical and physical properties of living organisms. Armed with latest scientific instruments like telescopes, mass spectrometers and lasers, they attempt to explain the mechanism of biological processes. For this purpose, they apply their knowledge of mathematics, physics, chemistry and biology. Their scientific study works to provide a clear idea about the functions of brain, heart and muscles in living creatures, the process of light absorption by plants and so on. Their job includes observing the effects of drugs and hormones on tissues, to study the evolutionary process of plants and animals to comprehend the nature of genetics and to conduct tests to identify diseases like genetic disorders. Biophysicists have crucial role in developing drugs for the treatment of diseases like cancer. Stem cell is an important area of their scientific study. The credit of developing alternative fuels goes to biophysicists. They also deal with various environmental problems like pollution. With their specialized knowledge, biophysicists work to detect the molecular basis of several life threatening diseases. Moreover, they work on advanced molecular biology techniques like DNA sequencing, mutagenesis and cloning. What follows is a collection of the biographies, timelines, trivia and other information about the professional and personal lives of some of the world’s most famous biophysicists.
