Single polar compound bio-electret and its influence on the cell growth

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 T/spl alpha/ and I/spl alpha/ is 37/spl deg/C and 2/spl times/10/sup -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.
