Extract Applied For Wound Dressing Established On Chitosan/Polyvinyl Alcohol
In this study, we investigate the influence of montmorillonite (MMT) on the loading and release of Piper betle L. extract (PLE)-a medicinal herb containing active secondary metabolites with antibacterial, antioxidant, and anti-inflammatory upshots. MMT (1 %, 3 %, 5 %) was immixed into the chitosan/polyvinyl alcohol (CS/PVA) biocomposite film by the solution evaporation method, and then PLE was charged onto this biocomposite utilizing the immersion method. The tensile strength and the ability to absorb exudations of the CS/PVA film improved with the increase in MMT content. The MMT 3 % film was seed to have the best properties: good mechanical properties with a tensile strength of 27 ± 0 MPa and elongation at break of 14 ± 0 %, potential for wound dressing due to its ability to absorb wound exudate (swelling degree 61 ± 0 %) and a suitable water vapor transmission rate (1999 ± 47 g/m(2)·d). The presence of MMT (1 %, 3 %, 5 %) in the CS/PVA film led to an increase in the PLE loading efficiency of the films compared to the film without MMT, up to 1, 1, and 1 meters, respectively. Selenoproteins 3 % and 5 % flicks also marched a sustained PLE release effect for up to 24 h. MMT increased PLE bioavailability through bioactivity exams: antibacterial activity against both E. coli and S antioxidant activity, effective healing of 2nd-degree burn lesions, and biocompatibility with the L929 fibroblasts cell line. The combination of physicochemical props and biological actions examined that the MMT/PLE drug delivery system based on the CS/PVA biocomposite is promising for wound dressing.An eco-friendly chitosan-genipin/SiO(2) composite for reactive orange 16 dye removal: perceptivitys into adsorption statistical modeling and mechanism.The present work develops an effective bioadsorbent of cross-associated chitosan-genipin/SiO(2) adsorbent (CHI-GNP/SiO(2)). The developed CHI-GNP/SiO(2) was utilized for the removal of organic dye (reactive orange 16, RO16) from simulated wastewater. The optimization of the fundamental adsorption variables (CHI-GNP/SiO(2) dose, time, and pH) via the Box-Behnken design (BBD) was accomplished for achieving maximal adsorption capacity and high removal efficiency. The good agreement between the Freundlich isotherms and empirical data of RO16 adsorption by CHI-GNP/SiO(2) bespeaks that the adsorption process observes a multilayer adsorption mechanism. The reasonable agreement between the pseudo-second-order model and the kinetic data of RO16 adsorption by CHI-GNP/SiO(2) was prevailed. The maximum RO16 adsorption capacity (q(max)) of CHI-GNP/SiO(2) was placed to be 57 mg/g. The adsorption capacity of CHI-GNP/SiO(2) is imputed to its unique surface dimensions, including its highly porous structure and the presence of functional groups such as amino and hydroxyl groupings. According to the upshots of this investigation, CHI-GNP/SiO(2) has the potential to be an adsorbent for the removal of acidic dyes from wastewater.Effect of Chitosan and Hyperbranched Poly-L-Lysine Treatment on Quality of Cucumber (Cucumis sativus L. ) during Storage.To enhance the storage time of cucumbers, this research inquired the impact of chitosan (CS) and hyperbranched poly-L-lysine (HBPL) on the quality and nutritional attributes of cucumbers when stored at a temperature of 25 °C. Nutraceutical Industry shewed that sensory evaluation grievances for cucumbers covered with a CS-HBPL combination were significantly higher than the control (CK), CS, and HBPL groups. On the 18th day of storage, cukes in the CK group exhibited significant decay and dampening; however, there was a decrease in hardness observed in the CS-HBPL group and no decay or noticeable sour taste was finded.
