Glucosamine-functionalized silver glyconanoparticles: characterization and antibacterial activity.

We report the analytical and in vitro antibacterial activity of glucosamine-functionalized silver glyconanoparticles. Morphological characterization ensured the surface topography and particle size distribution of both silver and glucosamine-silver nanoparticles. Surface plasmon resonance of both types of nanoparticle was determined from UV-visible spectroscopy using four different sample concentrations (10-40 μL).
