Medical Biophysics

Articles on Medical Biophysics are concerned with studies and research findings that apply physics to describe biological process mainly for medical application. This discipline combines physics and physiology. Important areas of research include medical imaging (e.g. MRI, computed tomography, and PET), oncology and cancer diagnosis using radiolabelling and molecular imaging, and vasculature and circulatory system function.


Medical Biophysics Articles

Radiation target analysis of RNA
Ribozymes are polynucleotide molecules with intrinsic catalytic activity, capable of cleaving nucleic acid substrates.
