Fabrication, characterization and biological properties evaluation of bioactive scaffold based on mineralized carbon nanofibers.

Tissue engineering as an innovative approach aims to combine engineering, biomaterials and biomedicine to eliminate the drawbacks of conventional bone defect treatment. In the current study, we fabricated bioengineered electroactive and bioactive mineralized carbon nanofibers as the scaffold for bone tissue engineering applications. The scaffold was fabricated using the sol-gel method and thoroughly characterized by SEM imaging, EDX analysis and a 4-point probe.

Evaluation of two fungal exopolysaccharides as potential biomaterials for wound healing applications.

Microbial exopolysaccharides (EPSs) are mostly produced by bacteria and fungi and have potential use in the production of biomedical products such as nutraceuticals and in tissue engineering applications. The present study investigated the in vitro biological activities and in vivo wound healing effects of EPSs produced from a Sclerotium-forming fungus (Sclerotium glucanicum DSM 2159) and a yeast (Rhodosporidium babjevae), denoted as scleroglucan (Scl) and EPS-R, respectively. EPS yields of 0.

Co-electrospun nanofibrous mats loaded with bitter gourd (Momordica charantia) extract as the wound dressing materials: in vitro and in vivo study.

Background: Interactive dressings are innovatively designed to interact with the wound surface and alter the wound environment to promote wound healing. In the current study, we integrated the physicochemical properties of Poly (caprolactone)/ Poly (vinyl alcohol)/Collagen (PCL/PVA/Col) nanofibers with the biological activities of Momordica charantia pulp extract to develop an efficient wound dressing. The electrospinning method was applied to fabricate the nanofibers, and the prepared wound dressings were thoroughly characterized.

Genotoxicity assessment of carbon-based nanomaterials; Have their unique physicochemical properties made them double-edged swords?

Carbon-based nanomaterials (CNMs) have attracted a great deal of attention because of their outstanding combinations of physicochemical properties. The unique physicochemical properties of CNMs have made them promising nanomaterials (NMs) for a large number of applications. However, these size-dependent properties serve as a double-edged sword, which makes them fascinating materials with specific features.
