Research Abstract

We synthesized phosphorylated polysaccharides as the carrier for bactericide delivery. It was indicated that 0. 01% phosphorylated pullulan and 0. 01% cetylpyridinium chloride(CPC) consistently exhibited an antibacterial effect, even after rinsing with distilled water, although CPC at a concentration of 10% showed no effect on bacterial growth after slight rinsing. Furthermore, phosphopullulan exhibited a controllable drug release property for antibacterial and anticancer agents.
