Abstract Recently, there has been a lot of interest in the fabrication metal oxide nanoparticles (NPs) due to growing importance developing recyclable assets, affordable methods, sustainable substances, and safe compounds. The current study demonstrates environmentally friendly ZnO NPs through use an aqueous extract derived from discarded eggshells. analysis involved UV, x‐ray diffraction (XRD), Fourier‐transform infrared spectroscopy (FT‐IR), field‐emission scanning electron microscopy (FE‐SEM) with EDX techniques. anti‐germs effects fabricated on pathogens were investigated using agar diffusion technique. cell‐damaging assessed MTT assay, whereas photodecomposition capacity was examined Congo red methylene blue dye. X‐ray revealed existence tetragonal crystal morphology. generated have crystallite size 17.6 nm. According FE‐SEM examination, created sample's average grain determined be between 20 30 production showed remarkable properties against human pathogenic organisms had good efficacy damaging Osteosarcoma cell lines (MG‐63) during experiment. Additionally, it emerged that manifestation catalytic efficiency fell by 78.1% after 60 min for blue. Based findings, shows great potential across multiple fields such as anti‐germs, anti‐proliferative, properties.

Fungi are the most frequent microorganisms that cause seed damage throughout development, wreaking much more post- and pre-infections significantly reducing quality. Conventional antifungal agents have failed to overcome a variety of Aspergillus spp. These strains been associated with development high-potency mycotoxins, which mould infections in fruits vegetables as well harmful health effects. Different species, such Aspergillus, Penicillium, Alternaria, Fusarium were isolated from imported yellow corn samples; however, was prevalent fungus. The current work attempts synthesize novel, effective nanomaterials stable by employing efficient approaches. An extract Matricaria chamomilla L. used biosynthesis silicon dioxide nanoparticles (SiO2 NPs) at room temperature. Ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), Zeta analyses characterize biosynthesized NPs. average size SiO2 NPs found be 17-28 nm. TEM images confirm biogenesis spherical-shaped, well-dispersed zeta potential graph shows negative value (-31.0 mV). activity M. extract, NPs, combined investigated against A. niger isolate compared miconazole. revealed higher than miconazole inhibition zones 25±0.54, 17±0.37, 20±0.61 13±0.23 mm, respectively. This provides good alternate technique is an agent, supplemented niger, pathogen for humans crop plants.

Synergistic effect of zinc oxide-cinnamic acid nanoparticles for wound healing management: in vitro and zebrafish model studies

BMC Biotechnology, Journal Year: 2024, Volume and Issue: 24(1)

Published: Oct. 10, 2024

Wound infections resulting from pathogen infiltration pose a significant challenge in healthcare settings and everyday life. When the skin barrier is compromised due to injuries, surgeries, or chronic conditions, pathogens such as bacteria, fungi, viruses can enter body, leading infections. These range mild severe, causing discomfort, delayed healing, and, some cases, life-threatening complications. Zinc oxide (ZnO) nanoparticles (NPs) have been widely recognized for their antimicrobial wound healing properties, while cinnamic acid known its antioxidant anti-inflammatory activities. Based on these combination of ZnO NPs with (CA) was hypothesized enhanced efficacy addressing promoting healing. This study aimed synthesize evaluate potential ZnO-CN multifunctional agent treatment. were synthesized characterized using key techniques confirm structure composition. The evaluated through standard vitro assays, demonstrating strong free radical scavenging inhibition protein denaturation. activity tested against common pathogens, revealing effective at minimal concentration. A zebrafish model employed assess both safety therapeutic nanoparticles, showing no toxicity concentrations facilitating faster closure. Additionally, pro-inflammatory cytokine gene expression analyzed understand role mechanisms. In conclusion, demonstrate potent antioxidant, anti-inflammatory, making them promising candidates Given properties non-toxicity concentrations, hold clinical management, warranting further investigation human models.
