A novel synthetic approach to produce cellulose-based woven scaffolds impregnated with bioactive glass for bone regeneration

Tissue-engineering has become the best alternative solution for replacing the damaged tissues. However, the cost of scaffold materials is still a big challenge, so the development of cost-effective scaffolds is highly encouraged. In this research, different types of cotton textile-scaffolds as a cellulosic material were developed to be utilized as a substrate for cells proliferation. They were loaded with bioactive glass (BG) doped with silver nanoparticles (AgNPs). The effect of the loaded materials on the physicochemical and mechanical characteristics of the cellulosic textile scaffolds was investigated by means of FTIR, contact angle, physical and mechanical properties of the cotton fabrics, in addition to assessing their antimicrobial activity. Moreover, the biomineralization was evaluated after soaking in Simulated Body Fluid (SBF) using ICP and SEM accessorized with EDX. Cells proliferation capacities of the developed cellulosic woven-scaffolds were assessed against MG63 cell line at different incubation times. The physicochemical and mechanical features of these fabrics demonstrated a positive influence for the existence of BG impregnation, especially those doped with AgNPs. The antimicrobial features were also affirmed for the cellulosic scaffolds. More pronounced influence was observed on the biomineralization of the scaffold impregnated with BG doped with 0.5% Ag. The percentages of proliferated cells were very close to negative control (100% ± 10). This approach offers a novel and affordable alternative cellulosic woven-scaffolds for bone regeneration. •Affordable cotton textile scaffolds were developed for bone regeneration.•Enhanced physicochemical and mechanical features by BG impregnations.•Antibacterial, bioactivity and cell proliferation are achieved.
