“…Porous scaffolds are mostly fabricated by: (i) utilizing porogens to control the preferred shape and the pore size in the scaffold; (ii) prototyping; (iii) layer-by-layer cell and woven or non-woven nanoscale fibers through the electrospinning method; and (iv) the most latest, 3D or even four-dimensional (4D) printing [41,42]. Porous scaffolds have been applied for developing tissues, organs, and rigid tissues (for example bone) [43,44,45,46,47,48,49,50,51,52,53,54].…”

“…Nano-scale fibers are made by methods such as phase separation, self-assembly, drawing, melt blowing, template synthesis, centrifugal spinning, and the more extensively applied electrospinning approaches [55,56]. The nano-scale fibers are sometimes precisely functionalized via a simple blending (or mixing) or coating procedure, or through surface grafting polymerization for embedding ligand molecules and adhesive proteins onto the nanofiber surface [47,48,49,50,52]. Nanofibrous scaffolds are broadly used for rigid and soft tissue engineering applications.…”

“…Thus, polymer composites prepared from polymers and bioceramics have enhanced mechanical properties as well good degradability behavior [76]. More recently, several research groups have reported fabrication of bioceramic composite scaffolds based on natural/synthetic polymers in combination with nano-hydroxyapatite (n-HAP) [77,78,79,80,81], or a combination of bioceramic particles [50] for bone tissue regenerations. Moreover, while HAP has been a staple of attention for bone tissue engineering, highly crystalline HAP can be non resorable and, thus, present an environmental hazard.…”

In recent decades, regenerative medicine has merited substantial attention from scientific and research communities. One of the essential requirements for this new strategy in medicine is the production of biocompatible and biodegradable scaffolds with desirable geometric structures and mechanical properties. Despite such promise, it appears that regenerative medicine is the last field to embrace green, or environmentally-friendly, processes, as many traditional tissue engineering materials employ toxic solvents and polymers that are clearly not environmentally friendly. Scaffolds fabricated from plant proteins (for example, zein, soy protein, and wheat gluten), possess proper mechanical properties, remarkable biocompatibility and aqueous stability which make them appropriate green biomaterials for regenerative medicine applications. The use of plant-derived proteins in regenerative medicine has been especially inspired by green medicine, which is the use of environmentally friendly materials in medicine. In the current review paper, the literature is reviewed and summarized for the applicability of plant proteins as biopolymer materials for several green regenerative medicine and tissue engineering applications.

“…Phosphate bioactive glasses (PBGs) are a promising alternative to conventional silicate glasses for bone repair and reconstruction due to their adjustable chemical resistance that can be customized to meet specific application requirements [1][2][3][4]. Bioactive glasses (BGs) are attractive materials for tissue regeneration because of their biocompatibility and angiogenic and osteogenic characteristics [5,6].…”

This study investigates the influence of silver oxide (Ag2O) concentration on the optical characteristics of phosphate bioactive glasses (PBGs). PBGs have emerged as promising alternatives to conventional silicate glasses in the medical field due to their excellent bioactivity and chemical resistance. Samples with varying Ag2O concentrations (0, 0.25, 0.5, and 0.75g) were sintered at 780°C for 2 hrs in an electric furnace. The samples were subjected to Fourier transfer infrared spectroscopy (FTIR), ultraviolet-visible (UV-Vis) spectroscopy, and photoluminescence (PL) tests to assess their functional groups and optical properties. By analyzing the FTIR spectrum of phosphate bioactive glass containing different amounts of Ag2O, it is possible to identify changes in the vibrational modes associated with Ag-O bonds and to gain insights into the structure and composition of the material. Because Ag-O bonds exhibit infrared vibrational modes, introducing Ag2O changed the FTIR spectrum. As Ag2O concentration increased, Ag-O vibrational modes strengthened, indicating more Ag-O bonds. UV-Vis spectroscopy, with increasing Ag2O concentration, the peak location shifted towards shorter wavelengths. Optical spectra show distinct UV absorption in the prepared glass spectrum, extending to near visible with increasing Ag2O content. The PL spectra peaks and band gap energies revealed that Ag2O altered the glass's electrical structure and optical activity. These discoveries help optimize metal-phosphate bi-active glass for biomedical implants and UV-blocking coatings. The melting-annealing technique prepared glasses based on the base host Na2O-CaF2-P2O5 system with increasing Ag2O as additives or loading (0.2 to 1 wt%).
