Abstract :
All kinds of compound bio-electrets of I&III collagen/chitosan have been developed. Their TSDC curves are analyzed, and the compound bio-electret I&III collagen/chitosan whose Tα and Iα is 37°C and 2×10-9 A respectively in the polarized state is selected. The study shows that the compound bio-electret can promote normal cell growth when single negatively polarized, and can inhibit cancer cell growth when single positively polarized. It proves that the rational designation of compound bio-electret has a broad applicable use to clinical medicine
