“…It is now identified that the increased permeation retention, reduced lymphatic drainage and vasculature leaking of cancerous cells facilitate the increase of intravenously injected NPs in the tumor tissue [96,97]. Silver nanoparticles induced apoptosis in cancerous cells, as they are more acidic [98,99]. It has been stated that caspase signaling induced by AgNPs causes cancer cell death due to an increase in free radical scavenging properties [100].…”

The zinc oxide‐silver oxide nanocomposite (ZnO.Ag2O3 particles) was prepared by using an aqueous plant extract of Haplophyllum obtusifolium for the first time. Powder X‐ray diffraction (PXRD), Fourier transforms spectroscopy (FTIR), field emission microscopy (FESEM), energy dispersive X‐ray analysis (EDX), and transmission electron microscopy (TEM) were applied to analyze the structure, functional groups, morphology, and purity of the prepared nanocomposite. PXRD revealed the formulation of ZnO.Ag2O3 for the particles. The investigation of functional groups has demonstrated the presence of some carbonated impurities along with absorbed water in the composition of the ZnO.Ag2O3 nanocomposite. Morphologically, particles have formed a petal‐like shape with different sizes. The EDX analysis also confirmed the composition of the prepared sample and the presence of 4.78% silver in the formula. Additionally, the TEM analysis revealed spherical and rectangular shapes with a particle size of 80.43 ± 46.73 nm. Moreover, the ZnO.Ag2O3 particles were used against cancer cells, which has shown synthesized NCs have a toxic effect against liver cancer cells in a concentration and time‐dependent manner.

“…Cancer is a leading cause of death and a worldwide health problem [51]. Cancer is a disease characterized by uncontrolled cell proliferation that spreads from an initial focal point to other parts of the body to cause death [52,53]. In the past few decades, the application of nanocomposites in cell toxicity and anticancer properties has attracted a lot of attention with several nanoparticle types being used [54].…”

A copper oxide/cerium oxide nanocomposite (CuO/CeO2, NC) was synthesized via a novel method using a metal–organic framework as a precursor. This nanomaterial was characterized by Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (PXRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), dynamic light scattering size analysis (DLS), and zeta potential. The PXRD showed the successful synthesis of the CuO/CeO2 NC, in which the 2theta values of 35.55° (d = 2.52 Å, 100%) and 38.73° (d = 2.32 Å, 96%) revealed the existence of copper (II) oxide. FTIR analysis showed the CeO2, hydroxyl groups, absorbed water, and some residual peaks. The solid phase analysis by FESEM and TEM images showed mean particle sizes of 49.18 ± 24.50 nm and 30.58 ± 26.40 nm, respectively, which were comparable with crystallite size (38.4 nm) obtained from PXRD, but it appears the CuO/CeO2 NC was not evenly distributed and in some areas, showed it was highly agglomerated. The hydrodynamic size (750.5 nm) also showed the agglomeration of the CuO/CeO2 NCs in the solution, which had a negatively charged surface. The CuO/CeO2 NCs showed anti-proliferative activity against human breast cancer cell line (MCF-7) in a dose- and time-dependence way, while affecting normal cells less significantly.

Objectives: Cerium oxide nanoparticles were synthesized by a rapid green method using an aqueous leaf extract of Bacopa monnieri to investigate its antioxidant activity. Methods: Cerium oxide nanoparticles (CeO 2 NPs) were synthesized using Bacopa monnieri leaf extract as a stabilizing agent by solution combustion method. Characterization techniques like FTIR, PXRD,SEM-EDAX, HR-TEM, UV-visible, and Raman spectroscopy confirmed the synthesized NPs. The antioxidant capacity was assessed by in vitro Hydroxyl radical scavenging assay. Findings: The biosynthesized CeO 2 NPs possess tiny spherical shapes and sizes ranging from 5-50nm, and the average particle size is 27 nm as measured by HR-TEM. XRD and Raman confirm the nanoparticle's polycrystalline nature and face-centered cubic fluorite structure with maximum UV-visible absorbance at λ max 301.2nm. The biosynthesized CeO 2 NPs exhibited better scavenging activity than Vitamin C. However, further in vitro and in vivo studies must be warranted to explore its mechanism and therapeutic potential. Novelty: To the best of our knowledge, this is the first report involving the green synthesis of cerium oxide nanoparticles using Bacopa monnieri leaf extract, which exhibited potent hydroxyl radical scavenging activity which can be a promising therapeutic candidate in oxidative stress-related disorders.
