Fabrication and Evaluation of Graphene Oxide/Hydroxypropyl Cellulose/Chitosan Hybrid Aerogel for 5-Fluorouracil Release.The incorporation of graphene oxide (GO) into a polymeric drug carrier can not only enhance the loading efficiency but also reduce the initial burst and consequently improve the controllability of drug release 5-fluorouracil (5-Fu)-loaded hydroxypropyl cellulose/chitosan (HPC/CS@5-Fu) and GO/HPC/CS@5-Fu aerogels were successfully manufactured through chemical cross-uniting with glutaraldehyde the received aerogels were characterised utilising skiming electron microscopy (SEM), Fourier transform infrared (FITR), X-ray diffraction (XRD), differential reading calorimetry (DSC), thermogravimetry (TG), and the effect of HPC and GO content on the drug loading (DL) and encapsulation efficiency (EE) for the two aerogels were inquired, respectively the drug release behavior of the GO/HPC/CS@5-Fu aerogels with different GO content was valued at two different pH values, and four forms of kinetic mannequins were used to evaluate the release behavior.Fabrication and characterization of polycaprolactone/chitosan nanofibers controling antibacterial brokers of curcumin and ZnO nanoparticles for use as wound dressing.The potential of the nanoscale structure is used by electrospun nanofibers, which are assuring fabrics for wound fertilisations we readyed wound dressings representing polycaprolactone (PCL) and chitosan (CS). Curcumin (Cur) and zinc oxide nanoparticles (ZnO) as antibacterial factors were implanted in PCL/CS electrospun nanofibers and different properties including morphology, physicomechanical, interaction with water, antibacterial efficiency, and in vitro bailiwicks were enquired.  Antioxidants  confirmed the nanofibrous structure of samplings with 100 ± 5 to 212 ± 25 nm in average diameter.

Dietary Supplement Market  of nanofibers showed a good distribution of ZnO along nanofibers which not only stimulated minifying in nanofiber diameter but also increased tensile strength of nanofibers up to 2 ± 0 MPa and with good elongation at break of 39 ± 2. ZnO nanoparticles also helped the interaction of nanofibers with water, and this led to the highest water vapor transition rate, which was equal to 0 ± 0 g cm(-2) day(-1). The sample arresting 3 wt% Cur had the highest water uptake value (367 ± 15%) and the lowest water contact angle (78 ± 3°), although Cur has a hydrophobic nature. The release profile of Cur demonstrated a two-stage release and the Peppas model foretelled a non-fickian diffusion. Simultaneous incorporation of CS, ZnO, and Cur effectively suppressed bacterial growth. In addition, in vitro studies exemplifyed that high content of Cur falls cell viability and cell attachment. The results from the fabricated nanofibrous scaffolds proved appropriate dimensions for application as a wound dressing.

Assessment of Chitosan Coating Enriched with Free and Nanoencapsulated Satureja montana L. Essential Oil as a Novel Tool for Beef Preservation.The effect of chitosan coating enriched with free and nanoencapsulated Satureja montana L. essential oil (EO) on microbial, antioxidant and sensory characteristics of beef was analysed. Different absorptions of free Satureja montana L. EO (SMEO) and nanoparticles (CNPs) were added to chitosan finishings, namely 0%, 0% and 1%. The beef samplings were swallowed in the chitosan applications and stored at +4 °C for 20 days.

In this period, the varietys in pH value, total viable count (TVC), lactic acid bacteriums, psychrophilic bacteriums and Pseudomonas spp. were examined. The lipid oxidation of beef was determined by the TBAR assay, while sensory analysis was performed by means of the descriptive evaluation method the influence of chitosan coating with CNPs on the growth of the tryed micro-organisms was more pronounced likened to SMEO. Treatment with caking enriched with 1% CNPs ensued in the reduction in TVC and Pseudomonas spp. by 2 and 3 log CFU/g, equated to the control, respectively.
