Abstract

The present invention provides a cationic β-cyclodextrin and a preparation method and uses thereof, as well as a cationic β-cyclodextrin functionalized silver nanoparticles and a preparation method and uses thereof. The cationic β-cyclodextrin of the present invention is introduced with an amine group and quaternary ammonium groups, while retaining the special structure and properties of cyclodextrin itself. The amine group contained in the structure plays a role in reducing and complexing Agin the synthesis of AgNPs, and plays a certain role in stabilizing nanoparticles and forming a complex in combination with quaternary ammonium groups.
