Two new chitosan oligosaccharide derivatives are synthesized for the surface modification of gold nanospheres and nanorods (see figure). These biopolymers have multiple thiols (ca. 6 thiols per polymer molecule) (polymer I) or oleic acids (polymer II) for the effective anchoring to the nanoparticle surface, as well as primary amine groups for further bioconjugation.
