Sustained broad-spectrum antibacterial effects of nanoliposomes loaded with silver nanoparticles.

Background: The emergence of microbial resistance to antibiotics warrants the search for effective broad-spectrum antibacterial agents. Silver nanoparticles (AgNPs) have been used as antimicrobial agents. AgNPs encapsulated in nanolipososmes have been developed as effective antimicrobial agents.

Controlled synthesis and characterization of hollow flower-like silver nanostructures.

Background: The synthesis of anisotropic silver nanoparticles is a time-consuming process and involves the use of expensive toxic chemicals and specialized laboratory equipment. The presence of toxic chemicals in the prepared anisotropic silver nanostructures hindered their medical application. The authors have developed a fast and inexpensive method for the synthesis of three-dimensional hollow flower-like silver nanostructures without the use of toxic chemicals.
