Effect of silver content on the structure and antibacterial activity of silver-doped phosphate-based glasses.
Staphylococcus aureus can cause a range of diseases, such as osteomyelitis, as well as colonize implanted medical devices. In most instances the organism forms biofilms that not only are resistant to the body's defense mechanisms but also display decreased susceptibilities to antibiotics. In the present study, we have examined the effect of increasing silver contents in phosphate-based glasses ...
متن کاملEffect of silver-doped phosphate-based glasses on bacterial biofilm growth.
Silver-containing phosphate-based glasses were found to reduce the growth of Pseudomonas aeruginosa and Staphylococcus aureus biofilms, which are leading causes of nosocomial infections. The rates of glass degradation (1.27 to 1.41 microg.mm(-2).h(-1)) and the corresponding silver release were found to account for the variation in biofilm growth inhibitory effect.

Niobium doped silver lead borate glasses with the chemical composition (29-x) PbO-yAg2O70B2O3-xNb2O5 (where x= 0.1 to 0.5mol%, y= 1 to 5 mol %) have prepared by conventional melt quenching method.SEM/XRD technique confines glassy nature of the prepared samples. IR and UV optical absorption technique have been used to obtain the information concerning network structure. From the absorption edge ...
متن کاملStructural characterization by x-ray methods of novel antimicrobial gallium-doped phosphate-based glasses.
Antimicrobial gallium-doped phosphate-based glasses of general composition (P(2)O(5))(0.45)(CaO)(0.16)(Na(2)O)(0.39-x)(Ga(2)O(3))(x) (where x=0, 0.01, 0.03, and 0.05) have been studied using the advanced synchrotron-based techniques of Ga K-edge x-ray absorption spectroscopy and high-energy x-ray diffraction to provide a structural insight into their unique properties. The results show that the...
متن کاملStructure and properties of strontium-doped phosphate-based glasses.
Owing to similarity in both ionic size and polarity, strontium (Sr2+) is known to behave in a comparable way to calcium (Ca2+), and its role in bone metabolism has been well documented as both anti-resorptive and bone forming. In this study, novel quaternary strontium-doped phosphate-based glasses, containing 1, 3 and 5 mol% SrO, were synthesized and characterized. (31)P magic angle spinning (M...
