Background: Liver cancer is increasing in different parts of the world and fourth leading cause death globally. Objectives: The present study aims to synthesize analyze characterization gold nanoparticles (AuNPs) synthesized by Cichorium intybus extract evaluate their antioxidant cellular toxicity activity against liver cells (HepG2). Methods: AuNPs were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), fourier-transform infrared spectroscopy (FTIR). was assessed DPPH test, cytotoxicity analyzed MTT method. Results: results indicate that are crystalline materials with a particle size less than 100 nm, mean 23.94 nm. FTIR reveals presence biochemical groups act as reducing factors. demonstrate increases concentration, 87% inhibition free radical scavenging observed at 250 µg/mL. Cell cell lines (HepG2) demonstrated significant time- dose-dependent manner. percentage viability concentration 1000 µg/ml after 24, 48, 72 hours determined be 45%, 51%, 22%, respectively. Conclusions: revealed simple cost-effective environmentally friendly method could employed from food pharmaceutical industries.

Global cancer mortality is rising yearly due to various factors. Silver nanoparticles (AgNPs) are widely utilized for their low cost and antibacterial properties compared other noble metals. Here, AgNPs were synthesized using Cucurbita maxima leaf extract, which was analyzed by analytical instruments. UV-visible spectra showed an absorbance peak in the 410-420 nm range, while Fourier transform infrared exhibited bands at 653 cm−1, 1629, 2276, 3786 cm−1. X-ray diffraction major intensity peaks 38.1º two theta value with average crystallite size of 18.34 nm. The transmission electron microscope aggregation spherical-shaped AgNPs, 10-90 MTT assay that it highly effective against SiHa cervical cells a much lower IC50 (~8 µg/mL) capable pesticide removal highest efficiency pH 9.

ABSTRACT Selenium nanoparticles (Se‐NPs) were produced adopting an environmentally benign green synthetic approach from the waste biomaterial obtained apple peel extract (APE). The NPs characterized through UV–Visible spectroscopy (UV–Vis), atomic force microscopy (AFM), Fourier‐transform infrared (FT‐IR), X‐ray diffraction (XRD), field emission‐scanning electron (FE‐SEM), and transmission (TEM). spectra exhibited absorption peak λ max at 295 nm, confirming formation of Se‐NPs. AFM examination revealed roughness distribution nanoparticles, FT‐IR ascertained surface‐contained functional groups presence. XRD confirmed crystalline nature sample, FE‐SEM validated surface morphology size range 52 to 84 nm. TEM demonstrated spherical shapes Se‐NPs with a face‐centered cubic crystal nature, whereas analysis showed mean 70 minimum inhibitory concentration (MIC) 500 μg mL −1 against Candida spp ., namely, C. albicans , guilliermondii ciferrii their anti‐fungal activity in control minor statistical difference ( p < 0.05) dissemination zones inhibition for treatment these fungi. effects on MexA gene expression efflux pump role gene's down regulation treated fungal strains. multi‐drug resistant microbes.

Polycyclic aromatic hydrocarbons (PAHs) are pervasive organic pollutants in the environment that formed as an outcome of partial combustion matter. PAHs pose a significant threat to ecological systems and human health due their cytotoxic genotoxic effects. Therefore, immediate need for effective PAH remediation methods is crucial. Although nanomaterials PAHs, concerns regarding environmental compatibility sustainability remains. this study emphasizes integration with bioremediation methods, which might offer more sustainable ecofriendly approach remediation. A systematic search was conducted through scholarly databases from 2013 2023. total 360 articles were scrutinized, among 26 selected resonated application nano-bioremediation. These literatures comprise both comparative analysis only well There elevation 18.9 % removal liquid-phase samples, when comparing (52.2 %) nano-bioremediation (71.1 %). consistent trend observed soil successfully remove 60.8 75.1 respectively, indicating 14.3 improvement. Furthermore, review elaborated on various features led efficiency PAH. The also discussed strategies namely nanomaterial-assisted microbial degradation, enzyme-enhanced activity, nanomaterial-immobilized cells, nanomaterial-facilitated electron transfer, even some eco-green approaches remediate like biogenic nanomaterial PAHs.
