This study describes a novel biological route for the biosynthesis of silver oxide nanoparticles utilising the aqueous extract of Callistemon lanceolatus D.C. leaves. Formation of silver oxide nanoparticles was confirmed by UVÀvisible spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopeÀenergy dispersive X-ray spectroscopy and X-ray diffraction spectroscopy analysis. The biologically synthesised silver oxide nanoparticles were found to be 3À30 nm in size with spherical and hexagonal shape by high-resolution transmission electron microscope analysis. Furthermore, the biogenic silver oxide nanoparticles demonstrated significant (p < 0.05) dose-dependent antioxidant activity in various in vitro antioxidant methods. These particles also exhibited significant (p < 0.05) dosedependent and time-dependent cytotoxic activity towards brine shrimp nauplii. Moreover, the reported method is a simple, cost-effective and eco-friendly approach for the synthesis of silver oxide nanoparticles with useful pharmacological properties.

“…Recent reports disclose that nanoscale particles of silver and silver oxide (Ag 2 O) possess distinctive morphology and characteristics [5], and can be utilized as a prognostic method for treating a variety of diseases including different bacterial and fungal infections, tuberculosis, acquired immunodeficiency syndrome, retinal neovascularization, etc. [6,7]. Ag 2 O nanoparticles (AgONPs) in aqueous distribution exhibited an antitumor response in a transplanted Pliss lymphosarcoma tumor when administered intravenously [7].…”

Background: Development of novel strategies to kill cancer by sparing normal cells is of utmost importance. Apart from their known antimicrobial activity, only limited information has been recorded regarding the antitumor potential of biocompatible silver oxide nanoparticles (AgONPs). There is a need to evaluate the anticancer potential of biocompatible AgONPs in vitro. Methods: A new approach of utilizing the leaf extract of Excoecaria agallocha was used to synthesize AgONPs. This was then characterized by ultraviolet-visible spectrophotometry, nanoparticle-tracking analysis, and ζ-potential analysis. Cytotoxicity and apoptotic potential were evaluated with an MTT assay and an annexin V-binding assay against the murine melanoma (B16F10), murine colon cancer (CT26), murine lung adenocarcinoma (3LL), and murine Ehrlich ascites carcinoma (EAC) cell lines. Cellular localization of AgONPs was evaluated on fluorescence microscopy. Results: UV peaks at 270 and 330 nm indicated the formation of nanoparticles (NPs) and the NP-tracking analyzer revealed them to have a size of 228 nm. AgONPs exerted initial cytotoxicity, specifically against all the experimental malignant cells by sparing the normal cell lines. Moreover, AgONPs exert apoptosis equally on all the malignant cells in vitro and ex vivo. This cytotoxicity possibly occurs via the nuclear translocation of AgONPs as analyzed in B16F10 cells. Conclusions: AgONPs utilizing natural sources would be a new medicinal approach against a broad spectrum of malignancy.

In this work, modify sol-gel method was used to synthesize nickel aluminate (NiAl 2 O 4 ) nanoparticles with aid of nickel nitrate hexahydrate and aluminium nitrate nonahydrate as the starting reagents in the presence of ethanol as the solvent. Besides, to examine the effect of different chelate agent such as citric acid monohydrate, oxalic acid, salicylic acid, and malic acid on the morphology and particle size of final products several tests were performed. The structural, morphological, and optical properties of as-obtained products were characterized by techniques such as Fourier transform infrared spectroscopy, X-ray diffraction, energy dispersive X-ray microanalysis, scanning electron microscopy and ultraviolet-visible. The photocatalytic degradation was investigated using methyl orange under visible light irradiation (k [ 400 nm). The resulting degradation rates of the methyl orange were measured to be as high as 90 % in 270 min.
