“…The incorporation of Sr and other modifiers within the network of borate BGs seems to be one of the most effective strategies used to face this issue. The effect of different bivalent modifier oxides (i.e., BaO, SrO, ZnO, and MgO) on melt-derived borate-based glasses was recently investigated in a study by Kumari et al (2017). MgO, SrO and BaO are conventional modifiers that enter the glass network by disrupting B–O–B, P–O–P and B–O–P bonds.…”

Improving and accelerating bone repair still are partially unmet needs in bone regenerative therapies. In this regard, strontium (Sr)-containing bioactive glasses (BGs) are highly-promising materials to tackle this challenge. The positive impacts of Sr on the osteogenesis makes it routinely used in the form of strontium ranelate (SR) in the clinical setting, especially for patients suffering from osteoporosis. Therefore, a large number of silicate-, borate-, and phosphate-based BGs doped with Sr and produced in different shapes have been developed and characterized, in order to be used in the most advanced therapeutic strategies designed for the management of bone defects and injuries. Although the influence of Sr incorporation in the glass is debated regarding the obtained physicochemical and mechanical properties, the biological improvements have been found to be substantial both in vitro and in vivo . In the present study, we provide a comprehensive overview of Sr-containing glasses along with the current state of their clinical use. For this purpose, different types of Sr-doped BG systems are described, including composites, coatings and porous scaffolds, and their applications are discussed in the light of existing experimental data along with the significant challenges ahead.

“…Ferraris et al in their research, have doubly surface functionalized two bioactive glasses with polyphenols (gallic acid or natural polyphenols extracted from red grape skins and green tea leaves) and silver nanoparticles deposited by in situ reduction from a silver nitrate aqueous solution [195]. Kumari et al synthesized calcium oxy fluoro boro phosphate glasses with fixed concentration of CuO and mixed with different modifier oxides (viz., BaO, SrO, ZnO and MgO) that play a vital role in collagen deposition, cellular activity, proliferation of osteoblasts and in blood vessel maturation, producing enzymes etc., that are necessary for normal functioning of human body [196]. Melli et al conducted a study on the evaluation of the microstructure and the effect of crystallization on the dissolution mechanism of a Bioglass®-based glass−ceramic scaffold, produced with a powder metallurgy inspired technology [197].…”

Bioactive glasses were discovered in 1969 and provided for the first time an alternative to nearly inert implant materials. They formed a rapid, strong, and stable bond with host tissues. This article examines the frontiers of research crossed to achieve clinical use of bioactive glasses and glass-ceramics. In the 1980s, it was discovered that bioactive glasses could be used in particulate form to stimulate osteogenesis, which thereby led to the concept of regeneration of tissues. Later, it was found that the dissolution ions from the glasses behaved like growth factors, providing signals to the cells. Hereby, the frontiers of knowledge crossed during four eras of development of bioactive glasses led from concept of bioactivity to widespread clinical and commercial use, with emphasis on the first composition, 45S5 Bioglases® were mentioned. The four eras are (a) discovery, (b) clinical application, (c) tissue regeneration, and (d) innovation. Questions still to be answered for the fourth era are included to stimulate innovation in the field and exploration of new frontiers that can be the basis for a general theory of bioactive stimulation of regeneration of tissues and application to numerous clinical needs.

In this work, we report the thermal, structural and anticorrosive properties of glasses from the xP 2 O 5 -yPbO-zB 2 O 3 system. The prepared materials were characterized using different techniques such as X-ray diffraction, Fourier transform infrared spectroscopy and (FTIR), scanning electron microscopy and differential scanning calorimetry (DSC). DSC analysis showed that the thermal stability increases with the increase of PbO and P 2 O 5 oxides contents. These results were confirmed by density and molar volume measurements. Furthermore, the structural evolution of the studied glasses was followed by FTIR vibrational spectroscopy, and it showed a cross-linking of the glass network upon incorporation of PbO. In addition, the study of the corrosion inhibition of C35 steel by glasses of the xP 2 O 5 -yPbO-zB 2 O 3 system showed that when concentrations of 70 and 700 ppm are used, the corrosion potential rises to around − 437 mV versus SCE, indicating that the glasses of the xP 2 O 5 -yPbO-zB 2 O 3 system change the stability of the metal/solution system to a different stable state. From 70 to 700 ppm, the inhibitor starts to have an effect on the anode current, but it is weaker than the cathode current. The results show that borophosphate glasses are effective corrosion inhibitors for C35 steel in a 1 M HCl environment. At 30 °C, the inhibitory efficiency is around 68% at a concentration of 70 ppm and increases with increasing inhibitor concentrations, reaching 86% at a concentration of 700 ppm.
