Recently, photo-degradation process under ultraviolet-light irradiation is being used as a substantial treatment method for the removal of environmental pollution. In this study, a silver phosphate-ilmenite (Ag3PO4-FeTiO3) hetero structure supported on glycol chitosan catalyst was completely prepared, also, and its structural, and optical properties were characterized. Meantime, scanning electron microscopy, X-ray diffraction, X-ray photoelectron, and UV-vis spectra were applied. The Ag3PO4-FeTiO3/glycol chitosan catalyst was used to degrade metronidazole under visible-light irradiation. The degradation rate of metronidazole in 25 min by Ag3PO4-FeTiO3/glycol chitosan nanocomposites was found to be 99.2% under UV light irradiation, which was higher than that by Ag3PO4-FeTiO3 (72.24%) and FeTiO3 (35.5%), respectively. The active species trapping test of Ag3PO4-FeTiO3/glycol chitosan indicated that ·OH and ·O2- participated during the reaction. https://www.selleckchem.com/products/epacadostat-incb024360.html The diffusion method was evaluated to appraise the bactericidal activity of the synthesized nanomaterials when tested against both Staphylococcus aureus and Escherichia coli bacteria, with or without LED-light irradiation. The antibacterial tests show higher inhibition zones under light illumination as compared to dark conditions. The antifungal properties of the prepared nanomaterials were analyzed by fungi (Aspergillus niger, and Fusarium solani) using disc diffusion analysis. It was confirmed that the prepared nanomaterials have the best antifungal agent as compared to the standard antibiotics. When the Ag3PO4-FeTiO3/glycol chitosan was used, the amount of inhibition zone was enhanced.The main purpose of this study was to explore the ability of a novel silica/polysaccharide polymer-based formulation, namely, chitosan/silica nanocomposites (CSNs), to directly affect Botrytis cinerea in vitro and in inoculated berries, and indirectly to induce natural host resistance via enzymatic and nonenzymatic antioxidants against gray mold of table grapes. The results indicated a positive correlation in in vitro tests in terms of radial growth, spore germination and germ tube elongation, where those parameters were completely inhibited by CSN at 1%. SEM and TEM investigations showed that morphological and internal structural damage was observed in B. cinerea-hyphae/spores treated with CSN. Additionally, most of the treated spores were affected, and cellular vacuolization and cytoplasmic disorganization were observed. The results revealed that CSN reduced gray mold incidence and severity on inoculated berries directly and indirectly. In direct activity, CSN (1%) reduced mold incidence and severity by 100% compared to the control. In indirect activity, mold incidence and severity was reduced by 51% and 64%, respectively. CSN significantly increased superoxide dismutase, ascorbate peroxidase, peroxidase, total phenol and flavonoid at 48 h post-treatment by 1.2-, 1.6-, 1.3-, 1.3- and 1.6-fold, respectively, in grape-treated tissues. It could be concluded that CSN, as a promising alternative control method against gray mold of table grapes, can directly affect the pathogen and indirectly enhance the natural host resistance of the antioxidant system.The effects of ball-milling on the pasting properties of waxy maize starch (WMS) and waxy rice starch (WRS) were investigated from a multiscale structural view. The results confirmed that ball-milling significantly destroyed the structures of the two waxy starches (especially WMS). Specifically, ball-milling led to obvious grooves on the surface of starch granules, a decrease in crystallinity and the degree of short-range order, and a reduction in double-helix components. Meanwhile, small-angle X-ray scattering results indicated that the semicrystalline lamellae of starch were disrupted after ball-milling. Ball-milling decreased the pasting temperatures. Furthermore, ball-milled starches exhibited lower peak and breakdown viscosity and weakened tendency to retrogradation. These results implied that ball-milling induced structural changes in starch that significantly affected its pasting properties. Hence, ball-milled starch may serve as food ingredients with low pasting temperature and paste viscosity as well as high paste stability under heating/cooling and shearing.A novel nanoparticle (NP) delivery carrier for curcumin based on electrostatic 6-deoxy-6-arginine modified chitosan (DAC) assembled by γ-poly-glutamic acid (γ-PGA) was prepared. The NP structure was evaluated using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Interactions between DAC and γ-PGA were characterized using Fourier transform infrared spectroscopy (FT-IR). The sustained release kinetics of curcumin-loaded NPs was investigated in simulated gastrointestinal fluids. After exposed to heating, pH, and NaCl aqueous solution, the stabilities of both normal and curcumin-loaded NPs were determined. The results showed that NPs achieved a high encapsulation efficiency (79.5%) and loading capacity (11.31%) for curcumin. The curcumin-loaded NPs displayed a sustained release profile under simulated gastrointestinal conditions. Under certain pH (3-9), salt (0-100 mM), and temperature (30 - 60 °C) conditions, the vehicles of curcumin showed better stability. This demonstrates that NPs can be used as stable carriers for curcumin.The creation of multi-functional bio-hydrogels with tunable properties that meet in vivo demands is significant but remains challenging. Inspired by host-guest chemistry, a novel multi-functional gelatin-based bio-hydrogel with tunable antibacterial and hemorheological properties (TAH-GEL) is synthesized via an in situ one-pot strategy. TAH-GEL not only exhibits excellent mechanical properties but also shows promising self-healing and bio-compatibility features. For the first time, this biomaterial presents controllable antibacterial and hemorheological properties by controlling the TAH-GEL polypseudorotaxane motif. The resulting bio-hydrogel is easy to prepare and delivers superior performance, making it a powerful tool for bio-applications, such as hemostatic materials.
