Structural 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 کاملEffect 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.
متن کاملStructural Characterization of fly ash doped lithium borate Glasses
Lithium borate glasses with fixed alkali content of 10 Mole % and different modifiers have been prepared. To compare the role of fly ash as a glass modifier the content of glass modifier PbO, Al2O3 have been kept same to 5 mole %. To investigate the structure FTIR and UV-VIS spectra of prepared samples have been taken. From optical data optical band gap and cutoff wavelength have been calculate...
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...
