Get PDFElectrospun blends of biphasic calcium phosphate (BCP) loaded polyvinyl alcohol (PVA)-gelatin (GE) were created with the aim of fabricating biodegradable scaffolds for bone tissue engineering. The process parameters including the electrical field and tip-to-collector distance (TCD) were investigated. The morphology of these hybrid scaffolds were characterized by scanning electron microscope (SEM). X-ray diffraction (XRD) was used to determine the crystallinity of the membrane. Adhesion of osteoblastic cells (MG-63) onto the BCP loaded PVA/GE composite nano-fiber mat was performed to assess potential of the product as a bone scaffold. This result suggests that the BCP loaded PVA/GE composite nano-fiber mat has a high potential for use in the field of bone regeneration and tissue engineering

Get PDFGold gelatin hydrogel nanocomposites crosslinked with genipin have been prepared, and the effect of citrate capped Au nanoparticles (NPs) as nanofillers in the crosslinking and swelling of gelatin and release of a model drug (methylene blue) from gelatin nanocomposites have been investigated. The citrate-capped Au NPs prevented the crosslinking reaction between the gelatin and genipin and resulted in less crosslinked hydrogels. Although less crosslinked, the Au gelatin nanocomposites swelled less than the unfilled crosslinked gelatin. The gelatin composites were optically active and thermo-sensitive in a temperature range acceptable for living cells. In vitro release studies demonstrated that the irradiation of the composite gels with monochromatic green light (10532 nm, 100 mW) increases the release of the encapsulated methylene blue, most likely due to the photothermal effect of Au nanoparticles. This opens the possibility to explore the application of these nanocomposites as carriers in remotely controlled light-triggered drug release
