The structure of binary glasses xMgO·(1−x)P2O5 (x = 0.30, 0.35, 0.40, 0.45, 0.50, and 0.55) was studied by thermodynamic model (TDM) of Shakhmatkin and Vedishcheva (SV) and Raman spectroscopy. In the TDM, six following system components were considered: MgO (M), P2O5 (P), MgO·2P2O5 (MP2), MgO·P2O5 (MP), 2MgO·P2O5 (M2P), 3MgO·P2O5 (M3P). The principal component analysis (PCA) of experimental Raman spectra resulted in three independent components. The baseline subtracted and thermally corrected Raman spectra were analyzed by the multivariate curve analysis (MCR) for three components. The MCR resulted in the Raman spectra and relative abundance of each component. The experimental spectra were reproduced by the MCR on the level of 99.9%. Correlation analysis attributed the MCR components to M2P, MP, and MP2. Then the Malfait’s decomposition was performed based on the TDM-SV equilibrium molar amounts of system components (MP2, MP, and M2P) resulting in partial Raman spectra (PRS). Normalized MCR loadings coincide with normalized PRS. Adjusted scores were reproduced with good accuracy equilibrium molar amounts of system components.

“…Based on the results of the in vitro cytotoxicity analysis, all specimens [except NR/BL0 (70/30)] revealed greater than 70% cell viability, as defined by ISO 10993‐5:2009 68 . Biocompatibility of any material for use in biomedical devices is evaluated through an in vitro cytotoxicity assay 69,70 . It was found that chitosan/45S5‐Ag biocomposites demonstrated similar results in terms of cytotoxicity using L929 fibroblasts, where the viability of the cells was greater than 70% 70 .…”

The objective of this work was to develop new NR‐based biocomposite containing BioS and/or BL0 particles, which exhibit better tensile response, biocompatibility, and bioactivity for biomedical applications. Morphological, tensile, thermal, and biological tests were performed on the biocomposites to evaluate the influence of BioS and BL0 particles on the properties of the NR matrix. According to TG/DTG tests, the decomposition profiles of the NR/BioS and NR/BL0 biocomposites were similar to those of NR, whose main event could be seen in the 290–450°C temperature range, indicative of NR's structural degradation. Tensile analysis demonstrated that the addition of BioS or BL0 to the NR‐based biocomposite improved the elastic modulus and the tensile strength at break (σat break) in comparison to NR. The σat break value of the NR matrix increased from 0.99 ± 0.06 MPa to 1.84 ± 0.09 and 2.29 ± 0.04 MPa for the NR/BioS and NR/BL0 specimens with 30 wt%. Indirect cytotoxicity testing revealed that NR, NR/BL0, and NR/BioS biocomposite specimens promote the attachment of MSCs cell, that is, greater than 70% viability as defined in ISO 10993‐5:2009. The results indicate that BioS and BL0 particles have improved the tensile response and biological properties of the NR matrix, resulting in a range of potential biomedical applications.

“…The size of pure BG ranges from 19.7 nm to 43.3 nm with an average of 31.32 nm while the size of AgBG particles ranges from 22.9 nm to 34.1 nm with an average of 29.66 nm. Bruti et al 20 observed agglomeration of pure BG as well as 5% and 10% AgBG particles with random shapes synthesized by the sol-gel method. According to them, agglomeration of the BG nanoparticles is possibly related to Ca, P and Ag fixation in the bioglass structure during heat treatment.…”
