Abstract: Actual problems in medical physics have been considered. Features in the cell membrane structure promoting the action of anticancer drugs are studied. The mechanism of an invasive method for measuring the blood pressure is analyzed. The tension distribution in the left ventricle wall was calculated. Conditions that prevent magnetic particles, nanodiamonds, and fullerene molecules, which are used to transport drugs in human body, to aggregate in liquid systems are determined. A molecular mechanism of electric welding of biological tissues has been proposed, as well as a method to study the surface of biological structures, by using ultrasound. The origin of structural changes in human hair under the influence of chemicals is determined.

Key words: cellular membranes, arterial pressure, cardiac muscle tension, drug transport, electric welding of biological tissues.
