Abstract : The project began with the general objective of utilizing electromagnetic forces in biological research methods. The phenomenon of electromagnetophoresis was discovered and explored. The possibility of stimulating irritable tissues without electrodes by alternating magnetic fields was demonstrated. The method of electromagnetic determination of blood flow was further developed and has become a standard method in biological and medical research, and in operating room blood flow measurements on human patients. The main investigations led to the conception of the method of isoelectric focusing which was demonstrated under ONR sponsorship and further developed in Sweden until it is now widely used in biochemical research as perhaps the most powerful method of protein analysis. Combination of electric and magnetic fields in a new configuration led to the development of the rotationally stabilized method of endless fluid belt electrophoresis which has high resolving power and is applicable to macromolecules as well as biological particles. This method is now being refined as it is put to use in measurements of electrokinetic properties of microorganisms. (Author)
