“…These exothermic peaks are the results of the combustion of residual organic compounds such as organic precursors. 6 Interestingly, in all analyzed samples there is no observation of any endothermic peak around 500 °C which is a result of nitrate decomposition and normally appears in the glasses synthesized by the conventional sol–gel method at room temperature. 10,25,26 This change could be due to the significant differences in synthesis methods.…”

“…Consequently, the bioactivity of synthetic glass systems tends to decrease rapidly. 6,9 More specifically, silver crystalline peaks at 38°, 44°, 64°, and 77° appear more obvious and exhibit stronger intensity in synthetic samples with higher content of Ag 2 O (Fig. 2).…”

“…Moreover, glasses synthesized by the sol–gel method have higher purity, porosity, specific surface area, and bioactivity than the glasses synthesized by the melting method. 4,5 In the sol–gel method, some biological beneficial elements such as silver (Ag), 6,7 copper (Cu), 8,9 strontium (Sr), 9 magnesium (Mg), 10 zinc (Zn), 11,12 and zirconia (Zr) 13 were added to synthetic glasses to control the bioactivity and biocompatibility. Moreover, beneficial elements were also incorporated into glass systems to produce new properties; for example, silver is incorporated into glass systems to induce antibacterial properties.…”

“…The decreasing intensity of crystalline peaks of combeite and cordierite indicated the lower presence of the crystalline phase after immersion in HBSS. This change represented the degradation of combeite and cordierite in HBSS, which indirectly showed their biodegradable properties [36], even at high sintering temperatures. The apatite peaks were also observed after immersion in HBSS for 14 days.…”

In this study, a composite of bioactive glass (BG) and cordierite (BG-cord) was proposed to increase the strength and bioactivity of BG. Both BG and cordierite were separately synthesized with the method of glass melting, then, they were used to fabricate BG-cord with a variation of sintering temperature (600 to 1000 °C). The highest diametral tensile strength (DTS=30.54 MPa) was shown by the BG-cord with sintering temperature at 925 ºC. Bioactivity tests were conducted by soaking in Hank's balanced salt solution (HBSS) for 7, 14, and 21 days. Apatite formation was examined by using a scanning electron microscope. The results showed that the sample showed good bioactivity with regards to the formation of apatite on the samples, confirmed by the detection of carbonate (C-O) and phosphate (P-O) absorption peaks by Fourier transform infrared spectroscopy and crystalline peaks in the X-ray diffraction pattern.

Characteristics of Hybrid Bioglass-Chitosan Coatings on the Plasma Activated PEEK Polymer

et al. 2023

Polyetheretherketone (PEEK) is a biocompatible, chemically and physically stable radiolucent polymer that exhibits a similar elastic modulus to the normal human bone, making it an attractive orthopedic implant material. However, PEEK is biologically inert, preventing strong enough bonding with the surrounding bone tissue when implanted in vivo. Surface modification and composite preparation are the two main strategies for the improvement of the bioactivity of PEEK. In this study, the plasma activated PEEK surfaces with the embedded bioglass, chitosan, and bioglass-chitosan mixed layers applying from the solution dip-coating technique were investigated. The most prominent factors affecting the coating biocompatibility are strictly connected with the composition of its outer surface (its charge and functional groups), hydrophilic-hydrophobic character, wettability and surface free energy, and topography (size of pores/substructures, roughness, stiffness), as well as the personal characteristics of the patient. The obtained surfaces were examined in terms of wettability and surface-free energy changes. Additionally, FTIR (Fourier Transformation Infrared Spectrometry) and SIMS (Secondary Ion Mass Spectrometry) were applied to establish and control the coating composition. Simultaneously the structure of coatings was visualized with the aid of SEM (Scanning Electron Microscopy). Finally, the obtained systems were incubated in SBF (Simulated Body Fluid) to verify the modifications’ influence on the bioactivity/biocompatibility of the PEEK surface. Different structures with variable compositions, as well as changes of the wettability, were observed depending on the applied modification. In addition, the incubation in SBF suggested that the bioglass-chitosan ratio influenced the formation of apatite-like structures on the modified PEEK surfaces.
