“…The Raman bands and shoulders situated in the first spectral domain at 340, 385 and 525 cm À1 are attributed to the O-P-O and P-O-P bending vibrations, respectively, while those that arise at 692 and around 755 cm À1 are assigned to the long-chain phosphate species and very short-chain or ring structures vibrations, respectively [33][34][35]. The Raman features from the second spectral range at 905 cm À1 are due to (PO 4 …”

“…In the last years [1][2][3][4] the development of phosphatebased glasses with high potential in biomedical applications has attracted much interest because of their physical and chemical properties. Most recently [5,6] calcium-phosphate based bioglasses have paid attention due to their valuable capabilities shown to the formation of degradable temporary scaffolds for the regeneration of hard and soft tissues, as they would eventually replace the natural tissue.…”

ZnO substituted 45S5 bioactive -glasses and glass -ceramics were prepared. In vitro bioactivity of bioactive glasses and glass -ceramics, before and after exposed to simulated body fluid (SBF) solution for different time periods, were investigated by fourier transform infrared (FTIR) reflectance spectrometer with measuring the pH and the concentrations of silicon, sodium, calcium, phosphorus and zinc ions in SBF solution. The density, micro hardness and flexural strength of bioactive glasses and glass -ceramics were measured. Experimental results show that in vitro bioactivity nearly remains same by doping 1% of ZnO by weight, but after that as well as ZnO content increases in vitro bioactivity decreases. Crystallization of bioactive glasses decreases in vitro bioactivity. The density, micro hardness and flexural strength of bioactive glass -ceramics are higher than their respective bioactive glasses and these are also increasing with the increase of ZnO content.

“…However, since it is very difficult to control adsorbed water content in the composites, this nano FHAp content is only an approximate value. In the TGA curves several steps are observed (Rajendran et al 2002;Singh et al 2008;Wang et al 2007). The first step, showing a small decrease in weight, is associated with adsorbed water-removing when heated above 90°C.…”

Among the composite materials, ceramic/ polymer possesses significant advantages of high mechanical reliability and excellent biocompatibility for applications in load-bearing areas. In this work, PVPCS(Poly (4-vinyl pyridine-co-styrene))/FHAp nanocomposites of varying weight percentages were synthesized and characterized physical-chemically by XRD, FTIR, 31 P NMR, TGA, DTA, and FE-SEM and biologically by antimicrobial and anti-inflammatory assays for evaluating their potential use for biomedical applications. The results indicated that the size and crystallinity of FHAp nanoparticles decrease with increase in PVPCS concentration in the composite. SEM confirmed the presence of FHAp nano rod crystals in PVPCS matrix. The nano PVPCS20/FHAp demonstrated the highest antifungal and antibacterial activity and favorable inhibition of human cell hemolysis. The designed PVPCS/FHAp nanocomposites constitute promising candidates for biomedical applications.
