Hyperthermia is an additional treatment method to radiation therapy/chemotherapy, which increases the survival rate of patients without side effects. Nowadays, Auroshell nanoparticles have attracted much attention due their precise control over heat use for medical purposes. In this research, iron/gold were synthesised using green nanotechnology approach. gold@hematite and characterised with rosemary extract in one step by X-ray powder diffraction, SEM, high-resolution transmission electron microscopy, photoelectron spectroscopy analysis. Cytotoxicity iron@gold against normal HUVEC cells glioblastoma cancer was evaluated 2,5-diphenyl-2H-tetrazolium bromide method, water bath hyperthermia, combined hyperthermia nano-therapy. minimal toxicity are safe cells. The gold shell around magnetic core magnetite caused environmental cellular biocompatibility these nanoparticles. These targeted transfer tumour tissue led uniform heating malignant tumours as most efficient therapeutic agent.

Abstract This contribution insight on the cytotoxic and anticancer activities molecular mechanism of phyto‐reduced silver nanoparticles (AgNPs) in MCF‐7 breast cancer cell lines. A simple, entirely green synthesis process was optimized for phyto‐reduction AgNP (~12.7 nm) using aqueous leaf extracts Indigofera heterantha . The structural vibrational properties biosynthesized AgNPs were extensively characterized UV–Vis spectrophotometer, x‐ray diffraction (XRD), dynamic light scattering (DLS), Fourier transform Infrared spectroscopy (FTIR), while their shape morphology studied through scanning electron microscopy (SEM). 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide (MTT) viability assay indicates concentration dependent inhibition with IC 50 , 27.93 ± 2.10 μg/mL against cells 294.38 3.87 L929 cells. manifested Acridine orange/ethidium (AO/EB), 4′,6‐diamidino‐2‐phenylindole (DAPI) Annexin‐V/propedium iodide fluorescence microscopic assays. level reactive oxygen species (ROS) measured DCFH‐DA fluorescent spectroscopy. Overall, results show that exhibit apoptotic effect by damaging membrane integrity nuclear fragmentation due to oxidative stress generated elevated ROS. Research Highlights Biomimetic nano dimension size (AgNPs). Characterization UV–Vis, DLS, XRD, FTIR, SEM. Cytotoxic effects fibroblast MCF7 respectively.

In this research, zinc oxide (ZnO) nanoparticles doped with different percentages of produced cobalt using the green synthesis method. ZnO showed good cellular and microbial toxicity due to their high surface-to-volume ratio. Adding metal nanostructure can lead appearance a new feature. To investigate effect adding metal, synthesized containing 3 6% were plant extract. The resulting nanostructures characterized by Raman spectroscopy, UV–Visible spectrometer, X-ray diffraction, Field emission scanning electron microscopy. Ultimately, samples' cytotoxicity antimicrobial tests performed. XRD confirmed formation hexagonal wurtzite structure. imaging that doping resulted in decrease average crystal size. results doping, particle size decreased slightly. effects all three studies, leads an increase compared non-doped nanoparticles.

The use of biosynthesized metallic and bimetallic nanoparticles (NPs) as biocides for plant protection has gained significant attention in recent years due to their potential sustainable ecofriendly crop protection. In this review article, we discussed the biosynthesis NPs using various biological sources such plants, fungi, bacteria, algae. We explore plausible mechanisms behind biocidal activity these NPs, including ability disrupt cellular structures, inhibit enzyme activity, induce oxidative stress, modulate defense responses. also highlight challenges limitations associated with toxicity nontarget organisms, impact on soil health, need standardized protocols synthesis characterization. Additionally, discuss strategies overcoming challenges, biocompatible stabilizers, controlled release formulations, targeted delivery systems.

Using the batch adsorption technique, an eco-friendly polymer composite made of chitosan, polyaniline, and iron (III) oxide was developed for removal dye contamination from wastewater. Ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission (TEM), EDX (energy dispersive analysis), thermogravimetric-derived thermogravimetric (TG-DTG) techniques were used to characterize sample. According EDX, Ch-PANI-Fe2O3 hybrid has following weight ratios: C 34.25%, N 0.48%, O 50.51%, Fe 3.08%. The nanocomposite’s surface rough with pleats, which evident SEM TEM images. This structure likely contributed higher rate (91.5%). analysis, proportion Fe2O3 nanoparticles chitosan–polyaniline changed hybrids’ morphology granular irregular, globular-like structure, supported by EDX. results demonstrated that this matrix (chitosan-PANI-Fe2O3) nanocomposite can be employed as adsorbent effective methyl orange dye, well wastewater reusability.
