A two-component tissue adhesive based on biocompatible and bio-degradable polymers (oxidized urethane dextran (Dex-U-AD) and gelatin) was prepared and photocrosslinked under the ultraviolet (UV) irradiation. The adhesive could adhere to surface of gelatin, which simulated the human tissue steadily. The structures of above Dex-U-AD were characterized by FTIR, 1 H NMR spectroscopy and XRD. The...
Gelatin/PVA bicomponent nanofibers were prepared via electrospinning, and its control release of Raspberry ketone(RK) was investigated. Significant diameter increase, tensile strength and elongation at break improvement were observed as the ratio of PVA increased. The burst release of drug was observed in the first hour, and reached a plateau after two hours. The RK release rate could be tailored...
