In this study, the bioactivity and the mechanical properties (Mechanical compressive stresses, Hardness, and density) of bioglass (BG) and bioglass/graphene oxide (BG/GO) were investigated. Bioglass in chemical composition [60SiO2_35CaO_5P2O5] was prepared via the sol-gel method. GO was added to the bioglass (BG) with different contents (0.5, 1, 2, and 3) wt.% named as 0.5%GO, 1%GO, 2%GO, and 3%GO samples respectively. The synthesized specimens were characterized by several techniques (FT-IR, XRD, and SEM). Compressive stresses, Hardness, and density were studied also by different techniques to obtain the optimum Mechanical samples. The biological activity was studied by an in-vitro test in simulated body fluid (SBF) for 33 days. Results showed that: the 0.5%GO sample exhibited optimum mechanical compressive strength by approximately 82% compared to the BG sample. Hardness was increased from 0.5%GO sample up to 1%GO sample compared to BG sample and gradually decreased in 2%GO Sample and 3%GO. Bioactivity results showed deposition of HA layer on the bioglass surface and there was no significant change in it with the addition of graphene oxide.

Cu- and Mg-doped mesoporous sol-gel bioactive glasses (MSGG) were developed and their microstructure was investigated. Selected biological tests were also performed to assess their suitability for the functionalization of polymer zein coatings. The electrophoretic deposition (EPD) conditions to obtain composite coatings on Ti-13Nb-13Zr substrates were determined. The coatings with excellent adhesion to the substrates were macroscopically uniform, exhibiting open porosity and high roughness. The surfaces of the samples coated with MSGG/zein coatings became more hydrophilic than the titanium alloy substrates. However, with an increase of the volume fraction of glass particles in the coatings, the contact angle increased. The coated alloy showed enhanced resistance to electrochemical corrosion in Ringer's solution. The chemical composition of the glass used in the coating affected the parameters of wettability and resistance to electrochemical corrosion. Both coating types showed an increase in the antibacterial properties against Gram-negative (E. coli) and Gram-positive (S. aureus) bacteria compared to pure zein. However, no significant differences were observed after a 24-hour-long test.
