Synthesis and Characterization of Chemically and Green-Synthesized Silver Oxide Particles for Evaluation of Antiviral and Anticancer Activity

Pharmaceuticals, Journal Year: 2024, Volume and Issue: 17(7), P. 908 - 908

Published: July 8, 2024

Silver oxide (Ag2O) particles are wonderful candidates due to their unique properties, and use in a wide range of research, industrial biomedical applications is rapidly increasing. This makes it fundamental develop simple, environmentally friendly methods with possible scaling. Herein, sodium borohydride Datura innoxia leaf extract were applied as chemical biological stabilizing reducing agents Ag2O particles. The primary aim was evaluate the anticancer antiviral activity prepared via two methods. XRD, UV-visible SEM analyses used examine crystallite structure, optical properties morphology, respectively. resulting green-synthesized exhibited small size, spherically agglomerated shape, high activities compared chemically synthesized MTT (3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium-bromide) assay showed against MCF-7 cells IC50 = 17.908 µg/mL 23.856 µg/mL. also evaluated by plaque-forming assay, higher ability 0.618 6.129 We propose cancer treatment drug delivery.

Comparative Study of Rare Earth Nd and Sm Doping on the Structural, Morphological, Optical, Magnetic, and Electromagnetic Traits of Mg-Zn-Cu Spinel Nanoferrites

ECS Journal of Solid State Science and Technology, Journal Year: 2024, Volume and Issue: 13(3), P. 037008 - 037008

Published: March 11, 2024

In the current study, magnetic nanoparticles of neodymium and samarium substituted Mg-Zn-Cu, with a chemical composition Mg 0.5 Zn Cu 0.05 R x Fe 1.95-x O 4 (x = 0.05; Nd, Sm) were produced via sol-gel auto-combustion route. XRD indicates evolution cubic symmetry having Fd3m space group no impurities at room temperature. The FESEM images show irregularly shaped agglomerated grains in all samples. FTIR examination reveals stretching vibrations among metal cations anions interstitial vacancies. M-H graphs demonstrates that prepared nanoferrites have low rentivity (0.18–0.84 emu g −1 ) coercivity (11.25–34.03 Oe) indicating formation superparamagnetic nature. From electromagnetic traits, observed sample’s real permeability ( μ ″) permittivity ε ′) along dielectric loss reduced increasing applied field frequency, typical behaviour spinel nanoferrites. This may be explained by Maxwell-Wagner interfacial polarisation electron hopping ferrous ferric ions. variations coercivity, anisotropy constant, traits provide strong evidence samples are thermally stable potential to used solenoids transformers, also, more resistive devices operate high frequency.

Synthesis, Characterization, and Evaluation of the Antimicrobial and Anticancer Activities of Zinc Oxide and Aluminum-Doped Zinc Oxide Nanocomposites

Pharmaceuticals, Journal Year: 2024, Volume and Issue: 17(9), P. 1216 - 1216

Published: Sept. 16, 2024

In this research, we developed undoped and aluminum-doped zinc oxide for antimicrobial anticancer activities. This study focuses on the synthesis, characterization, biological activities of nanoparticles (ZnO NPs) nanocomposites (Zn1−xAlxO NCs) at varying concentrations (x = 0, 0.25, 0.5, 0.75 wt%) using coprecipitation method. Various characterization techniques such as XRD, UV-Vis, FTIR, EDX, SEM were performed to analyze crystal structure, optical properties, functional group identification, elemental composition, surface morphology. The activity test showed that Zn0.75Al0.25O NCs exhibited strongest inhibition zone against Bacillus cereus compared Staphylococcus aureus > Pasteurella multocida Escherichia coli. Moreover, cytotoxicity cell viability liver cancer (HepG-2), breast (MCF-7), ovarian (SKOV3), normal lines) evaluated MTT assay, demonstrating not only enhance destruction but also show low high biocompatibility concentrations. These results suggest could be a promising candidate in vivo applications should further investigated.
