Abstract

The present invention provides a new type of hydrophobically -modified sodium alginate, which is synthesized by alginate and oleic acid linked with a spacer. The AGO macromolecule as obtained therefrom is amphiphilic and has clinically-accessible molecular size, and anti- cancer activity. The AGO nanoparticle formed therefrom shows excellent structural stability, colloidal stability, and biocompatibility in-vitro and in-vivo, and is expected to be useful in biomedical area, for example, used as a drug delivery system.
