Preparation of natural polysaccharide nanosphere carrier and its application in antitumor

Abstract With the rapid development of nanotechnology, more and more polymer materials have been excavated for the preparation of nano drug microspheres for the treatment of malignant tumors. Due to its wide range of sources, low price, good biocompatibility and degradability, natural polysaccharides are widely used in the research of nano-microsphere carriers to achieve sustained release control of embedded drugs. In this paper, we mainly introduce the preparation methods of chitosan, sodium alginate and chitosan-sodium alginate nanospheres and their application research in anti-tumor, and look forward to their future development.
