Silver nanoparticles deposited on calcium hydrogenphosphate – silver phosphate matrix; biological activity of the composite

The composite containing nanosilver uniformly deposited on matrix composed of CaHPO x 2H O (brushite, 89 mass %), CaHPO (monteonite, 9.5 mass%), and Ag PO (0.5 mas%) was obtained by addition of calcium nitrate and silver nitrate aqueous solution at 30:1 Ca:Ag molar ratio into excess of (NH PO soluti...

Beschreibung
Zusammenfassung:The composite containing nanosilver uniformly deposited on matrix composed of CaHPO x 2H O (brushite, 89 mass %), CaHPO (monteonite, 9.5 mass%), and Ag PO (0.5 mas%) was obtained by addition of calcium nitrate and silver nitrate aqueous solution at 30:1 Ca:Ag molar ratio into excess of (NH PO solution at pH 5.0 – 5.5. The isolated solid was characterized by STEM, XRD, and LDI mass spectrometry. It has been found that nanosilver was uniformly distributed within composite as
