Dielectric Analysis of Biomaterials.

Abstract

After introducing the frequency range and operating methods of dielectric analysis in general terms, the report reviews shortly the present state of knowledge about freezing injury, the role of water in living systems, the effects of dissolved ions, and the unique role of protons. Subsequently it shows that protons act quite differently than anticipated and that ions and molecules in frozen systems display surprising changes of action and unsuspected interactions as function of temperature. Studies on erythrocytes make clear that dielectric analysis can become a diagnostic tool for the measurement of cell permeability and changes of cell content. Methods and instrumentation for deep tumor therapy are proposed, based on the presently known dielectric characteristics of the human body. (Author)
