Synthesis, characterisation and antibacterial applications of water-soluble, silver nanoparticle-encapsulated -cyclodextrin

This paper describes a simple method for the synthesis of water-soluble, silver nanoparticle-encapsulated -cyclodextrin by phase transfer of silver nanoparticles from organic to aqueous phase using -cyclodextrin as a capping agent. -Cyclodextrin-silver nanoparticle inclusion complex was purified, characterised by spectroscopic and microscopic analyses and tested in vitro against Pseudomonas aeruginosa, Staphylococcus aureus, Serratia marcescens, Escherichia coli and Klebsiella pneumoniae. The silver nanoparticle-encapsulated -cyclodextrin inclusion complex displayed considerable antimicrobial activity and stability. [image omitted].
