“…). The broad vibration bands at around 994–1075 and 500 cm −1 were ascribed to the Si‐O‐Si asymmetric stretching and Si‐O‐Si bending, respectively . On the other hand, P‐O antisymmetric stretching was assigned to a band at 1000–1100 cm −1 , which could have overlapped with that of Si‐O‐Si asymmetric stretching .…”

Bioactive glasses (BGs) based on 50SiO2‐45CaO‐5P2O5 system doped with 1, 5, and 10 mol% CuO or Ag2O were separately synthesized using quick alkali sol‐gel method. Scanning electron microscope (SEM) analysis of the samples confirmed the formation of nano‐sized BGs, whereas Fourier transform infrared (FTIR) spectra showed characteristic peaks for silica and phosphate groups. X‐ray diffraction (XRD) pattern of the heat‐treated (700°C) samples revealed the presence of crystalline metallic silver phase in all Ag‐doped samples, while the XRD pattern of Cu‐doped and control sample (50Si‐45CaO‐5P2O5) also heat‐treated at 700°C confirmed their amorphous nature. Ultraviolet–visible (UV‐Vis) studies along with Energy‐dispersive X‐ray spectroscopy (EDX) analysis confirmed the successful incorporation of Cu and Ag in bioglass. Antibacterial properties of the synthesized BGs were investigated by quantitative viable count method, and the results were related to the ion release profiles of the samples studied by flame atomic absorption spectroscopy (FAAS). Fast initial release of Ag observed in this study makes Ag‐doped BG a better rapid bacteria‐killing agent than Cu‐doped BG, which exhibited a prolonged release of ions, suggesting that it may be a better candidate for long‐term antibacterial protection.

“…This problem causes lower bioactivity of the developed HA coating. Bioactive glass 45S5 and S520 proved higher stability than HA at high temperatures [11] [131]. The simulated body fluid test showed that bioactive glass S520 is more appropriate than 45S5 in laser cladding rapid prototyping [80].…”

“…These materials have very low fracture toughness (usually < 1 MPa.m 1/2 ) compared to cortical bones (2-10 MPa.m 1/2 ) [10]. In the other applications which no load or small loads are induced, the bioactive materials proved excellent treatment results, as an example the middle ear bones replacement [11].…”

“…In addition to their bioactivity and resorbability, glasses are relatively easy to shape and to produce in microporous structures, making them extremely useful in a variety of scaffold applications [36]. For example, a gel casting approach has recently been demonstrated which allows near net shape three-dimensional fabrication [37].…”

Biomaterials for repairing and regenerating parts of the human body play a key role in contemporary medicine, and have an increasing impact in modern society. Given the importance of orthopaedic medicine (bone is the second most replaced organ after blood), bioactive glasses and ceramics represent a key reference to guide technological advances in this field. Their established role in current biomedical applications has already led many research groups worldwide to look into their structural properties, with a view to identifying the molecular basis of their biological activity. As the efforts directed towards this crucial and exciting direction continue to increase, it is now timely to review the situation, in order to guide future investigations on structure–bioactivity relationships. In this introductory article, the field is reviewed, to provide an appropriate context for the contributions to this Theme Issue.
