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 proportion and concentration of nanometer fiber gel:IKVAV∶ RGD∶ FGL-PA =1 ∶ 1 ∶ 1,and 0.6 g/L by observing the liquidity,diffusion time and viscosity.The nanometer fiber gel had slow-releasing profile,its average particle size was 212.8 nm,and the slow release time was more than 4 days.The preliminary results confirmed that the structure of human placenta extract (HPE) encapsulated nanofiber gel was unvaried compared with the HPE structure.Conclusion This kind of novel composite nanocapsules may offer a promising delivery system for human placenta extract.
