Abstract
Gelatin/poly(epichlorohydrin-co-ethylene oxide) [GL: PECO] composites are synthesized in a one-step process by the incorporation of elastic PECO and diclofenac. [GL: PECO] fibers are prepared by Forcespinning®. GL: PECO fibers are capable of diclofenac, by conjugation via a labile amide linkage. Fourier transform infrared spectroscopy (FTIR) results confirmed the chemical reactions and hydrogen bonds between gelatin, PECO, and diclofenac. Diclofenac drug release from GL: PECO fibers are measured for 15 days and prolonged drug release is observed. The cell viability is studied with NIH/3T3 and excellent results are observed. The sustained drug release and cytotoxicity results reveal that GL: PECO fibers could be promising substitutes for skin tissue engineering, wound healing, and drug delivery.
