The histological analysis of hybrid fibrous patch could be evoked the applicability of this structure as suitable skin second-stringers to repair injured skin.Preparation of the Chitosan/Poly-γ-Glutamic Acid/Glabrid in Hybrid Nanoparticles and Study on its Releasing Property.AIM: The aim of this study was to encapsulate glabridin (GB) into nanoparticles, prepared by an ionic-gelation method immingled with chitosan (CS) and poly-γ-glutamic acid (γ-PGA) to address the issue of poor stability and low water solubility of glabridin The physicochemical holdings of nanoparticles were investigated by transmission electron microscope (TEM), dynamic light dispeling (DLS) and fourier-transform infrared (FT-IR) spectroscopy FT-IR solutions suggested that the spontaneous interaction between CS, γ-PGA and GB can form a cross united network-structure, passing to the spontaneous formation of nanoparticles. Morphology of the complex molecules was nano-scale spherical shape particle size was decreased according to the decrease of γ-PGA capacitys and CS, companioning with the increase of mixed solution transmittance. The m(γ-PGA ): m(GB) = 1: 1 and mCS: (m(γ-PGA )+ m(GB)) =1: 1 were studyed to be a proper preparation condition of CS/γ-PGA/GB hybrid nanoparticles, which produced the smaller nanoparticles with the satisfactory encapsulation efficiency (EE), loading content (LC) and supported GB release. With  fucose foods  of pH values, the potential, EE, and LC minifyed gradually, while the particle size increased.

The nanoparticles prepared with higher molecular weight γ-PGA had larger particle size and less loading capacity on GB. Additionally, moderate weight ratio of CS/γ-PGA/GB, low pH, and high molecular weight of γ-PGA were favorable for sustained release It can be closed that the physicochemical properties of nanoparticles and GB release doingsses were impacted by several brokers including the weight ratio of CS/γ-PGA/GB, pHvalues, and γ-PGA molecular weight (MW). Nanoencapsulation habituating CS, γ-PGA and GB has a potential application for the development of functional cosmetic merchandises with skin-whiting effect.checked synthesis of in-situ gold nanoparticles onto chitosan functionalized PLGA nanoparticles for oral insulin delivery.Chitosan-based nanoparticles (chitosan nanoparticles (ChNps), chitosan gold Nps (ChAuNps), and chitosan gold Nps functionalized with poly lactic-co-glycolic acid (PLGA) (ChAuNps/PLGA)) were organised as nanocarriers for insulin to improve its oral uptake. The emulsion solvent diffusion method was employed to functionalize the Nps with PLGA SEM, DLS, and zeta potential were beared to characterize the Nps. The morphological analysis confirmed the formation of spherical Nps with hydrodynamic particle sizes of 138±23, 16±2, and 50±9 nm for ChNps, ChAuNps, and ChAuNps/PLGA, respectively.

Zeta potential measures indicated two eccentrics of Nps, regardless of insulin entrapment, positively charged, (ChNps (+36 ± 4, +31 ± 2mv)) and ChAuNps (+37 ± 4, +33 ± 2mv) and negatively burdened (ChAuNps/PLGA (-31 ± 2, -26 ± 2 mv)). The in vitro cogitations were taxed by evaluating the entrapment efficiencies (EE%) and the release profiles of insulin at different pH values. EE% for ChNps, ChAuNps, and ChAuNps/PLGA were 97 ± 1, 98 ± 1, and 99 ± 1%, respectively. At an acidic medium, a significant level of insulin retention was discovered (96 ± 0%) for ChAuNps/PLGA. While a high amount was unloosened at higher pH values over an extended period of time. In vivo reports, diabetic rats treated with insulin-debased Nps had reduced blood glucose level (BGL) (38 ± 2, 35 ± 6, and 27 ± 5%) for ChNps ChAuNps and ChAuNps/PLGA, respectively. The pharmacological availability (PA%) and bioavailability (FR%) for insulin-laded ChAuNps/PLGA were 15 ± 0% and 7 ± 0%, respectively emphasize the role of biocompatible Nps and their efficiency in the convenient delivery of insulin, thus louring the BGL in a safe condition.
