Abstract
Chitosan-derived biomaterials, and, more specifically, chitosan modified by the addition of a monosaccharide or oligosaccharide side chain to its free amino groups. The modified chitosan ("glycated chitosan") is preferably stabilized by reduction. In one particularly preferred embodiment, a galactose derivative of chitosan ("galacto-chitosan") is provided. The chitosan-derived biomaterials are useful in a myriad of biomedical applications, including as an immunoadjuvant in laser/sensitizer assisted immunotherapy.
