  • METAL-POLYSACCHARIDE CONJUGATES: COMPOSITIONS, SYNTHESIS AND METHODS FOR CANCER THERAPY
    Publication number: 20120277409
    Abstract: The current disclosure, in one embodiment, includes a polysaccharide conjugate. This conjugate has a polysaccharide and at least one liner covalently bound to the polysaccharide. The conjugate also has at least one metal conjugated by said linker. According to another embodiment, the disclosure provides a method of synthesizing a polysaccharide conjugate by covalently bonding a linker to a polysaccharide to obtain an intermediate and by conjugating said intermediate to a metal to form a polysaccharide conjugate.
