Objective To describe a novel nanocomposite gel fiber encapsulated human placental extract through layer-by-layer self-assembly.Methods The 10 mg of isoleucine-lysine-valine-alanine-valine(IKVAV),Arg-Gly-Asp (RGD) and FGL peptide-amphiphile (FGL-PA) were screened and combined to produce an optimal vehicle nanofiber gel through layer-by-layer assembly.We detected its morphology,particle size,drug loading efficacy,the encapsulation rate,release efficiency and the structure validation after it was diluted 0,50,100 times.Results The optimal p...
