The projected biosensor demoed linear behavior across a wide range from 0 μM to 150 μM and reached a detection limit of 10 nM, with a sensitivity of 134(◦)RIU(-1).Olive leaf extract-descended chitosan-metal nanocomposite: Green synthesis and dual antimicrobial-anticancer action.In this study, we germinated a novel nanocomposite by synthesising zinc (ZnNPs), copper (CuNPs), and silver (AgNPs) nanoparticles employing olive leaf extract and incorporating them into a chitosan polymer. This approach combines the biocompatibility of chitosan with the antimicrobial and anticancer dimensions of metal nanoparticles, enhanced by the phytochemical richness of olive leaf extract. The significance of our research lies in its potential to offer a biodegradable and stable alternative to conventional antibiotics and cancer discourses, particularly in battling multidrug-resistant bacteriums and various cancer types. Comprehensive characterization through Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), and Transmission Electron Microscopy (TEM) sustained the successful synthesis of the nanocomposites, with an average size of ~22 nm.
Phytochemical analysis foregrounded the antioxidant-rich composition of both the olive leaf extract and the nanoparticles themselves the synthesized nanoparticles displayed potent antimicrobial activity against multidrug-resistant bacterial variants, outstriping traditional antibiotics by curbing key resistance genes (ermC, tetX3-q, blaZ, and Ery-msrA). In anticancer judgements, the nanoparticles showed selective cytotoxicity towards cancer cadres in a concentration-dependent manner, with CuNPs and AgNPs testifying particularly strong anticancer outcomes, while establishing minimal toxicity towards normal cubicles. ZnNPs were observed for their low cytotoxicity, spotlighting the safety profile of these nanoparticles. Further, the nanoparticles inducted apoptosis in cancer cubicles, as certifyed by the modulation of oncogenes (P21, P53, and BCL2), proposing their therapeutic potential. The determinations of our study underscore the versatile lotions of these biogenic nanoparticles in modernising safer and more effective antimicrobial and anticancer therapies.Insect chitosan/pullulan/gallium photo-crosslinking hydrogels with multiple bioactivities promote MRSA-infected wound healing.Methicillin-resistant Staphylococcus aureus (MRSA) and other drug-resistant bacteriums have went more common in recent twelvemonths, which has made it extremely difficult to treat and heal many different sorts of lesions and caused enormous financial passings.
Because of its unique "Trojan horse" function, Ga(3+) has been realised as a new possible candidate for inhibiting and eliminating drug-resistant bacteria natural polysaccharide cloths with outstanding biological features, such as insect chitosan (CS) and pullulan (PUL), have appealed significant interest. In this study, we used quaternized-catechol chitosan (QDCS-PA), methacrylate-dialdehyde pullulan (DPUL-GMA), and gallium ion (Ga) to create a multi-crosslinked photo-raised hydrogel (Q-D/Ga/UV) with antimicrobial, hemostatic, self-healing, and injectable properties for advancing MRSA-tainted wound healing. In vitro, the Q-D/Ga/UV hydrogels manifested good mechanical attributes, antioxidant capabilities, biocompatibility, hemostatic properties, and antibacterial activity. The addition of gallium ions enhanced the hydrogels' mechanical properties, hemostatic potentialitys, antibacterial activity, and ability to induce wound healing.
