Molecular Biophysics

Articles on Molecular Biophysics, the study of biomolecules and particles involving the application of the principles and techniques of experimental physics in its attempt to understand their functions in order to characterize, manipulate, and modify living systems. The most important physical tools used for such research are the electron microscope, ultracentrifuge, and x-ray diffraction camera.
