Chitosan nanoparticles suppress liver cancer growth

Abstract:
Nanoparticles made of chitosan, a naturally occuring polymer isolated from crab and shrimp shells, have shown promise as carriers of anticancer drugs, antitumor genes, and other novel therapeutic agents. In addition, chitosan nanoparticles by themselves appear toxic to various types of malignant cells. To better understand this latter observation, Lifeng Qi, Ph.D., at West Virginia University, working with colleagues at Zhejiang University in Hangzhou, China, has conducted a detailed study evaluating the effect of chitosan nanoparticles on human liver cancer cells.
