Hydroxyapatite supported antibacterial Ag3PO4 nanoparticles

High surface area hydroxyapatites have been explored as biocompatible supports for antibacterial applications. Porosimetry, XRD, XPS and XAS reveal that Ag-doped mesoporous hydroxyapatite promotes the genesis of potent Ag3PO4 nanoparticles, effective against Staphylococcus aureus and Pseudomonas aeruginosa. © 2010 The Royal Society of Chemistry.
