摘要：
The invention relates to a method for preparing a hybrid material containing polysaccharide nanocrystals and silver nanoparticles, which comprises a step of preparing an aqueous reaction medium containing native unmodified polysaccharide nanocrystals, a silver salt and a silver ion-reducing agent, and a reaction step of allowing said reaction medium sufficient time to obtain therein hybrid particles consisting of said polysaccharide nanocrystals on the surface of which are grafted silver nanoparticles.
