“…1 . The SPR absorbance is greatly sensitive to the shape, size, and nature of the particles and the surrounding medium (Mosleh-Shirazi et al 2021a , b ). At lower leaf concentration (g1), the Surface plasmon resonance (SPR) peak is broad with long wavelength absorption that indicates considerable anisotropy in the shape of Au NPs.…”

“…A great number of in vitro and in vivo experiments have confirmed the nontoxicity and biosafety of Au NPs, while some evidence indicates the toxicity of Au NPs for vital cells (Singh et al 2013 ).This could be due to different standard bases of the toxicity studies that explain the contrary results (Minetto et al 2017 ). Indeed several aspects, such as shape, size, surface charge, NPs concentration, and exposure time, could affect gold nanoparticles’ cytotoxicity (Sani et al 2021 ; Mosleh-Shirazi et al 2021a , b ). However, the type of cells selected for the cytotoxicity test is a conflicting issue in biosafety research because some cells, such as macrophages, fibroblasts, or epithelial cells, have revealed more sensitivity to gold particles (Pan et al 2007 ).…”

Nowadays, nanoparticles such as gold nanoparticles (Au NPs) with specific biophysical characteristics have attracted remarkable attention as innovative options for the diagnosis and treatment of different diseases. In the present research, Au NPs were green synthesized using the Glaucium flavum leaf extract as an inexpensive and eco-friendly synthesis method. Then, the physicochemical properties were characterized by transmission electron microscopy (TEM), dynamic light scattering method (DLS), scanning electron microscopy (SEM), X-ray diffraction (XRD), Ultraviolet–visible absorption spectroscopy (UV–Vis), Zeta potential, and Fourier transform infrared (FTIR) spectroscopy. Afterwards, the antioxidant capacity was tested and antiviral activity against influenza virus was evaluated by applying TCID50 and PCR assays. The nanoparticles cytotoxicity was tested using the MTT method. The shape and size of Au nanoparticles were modulated by varying leaf concentrations with face-centered cubic (FCC) structure. At higher concentrations, long-time stable spherical nanoparticles were obtained with a mean particle size of 32 nm and low aggregation degree that could simply combine with various bioactive compounds. The outcomes exhibited effective antiviral and antioxidant activities with low cytotoxicity and acceptable biocompatibility of green synthesized Au NPs. The aim of the present study was to develop a potentially environmentally friendly nanoplatform with excellent antiviral and antioxidant functions and acceptable biocompatibility for promising biomedical applications in the future.

“…Since natural coating agents can impart some functionality to the nanoparticles, such as antioxidant properties, anti-inflammatory properties, lower toxicity, modulation of immune response, etc., they are considered better candidates for use in human and veterinary medicine compared to nanoparticles obtained by physical and chemical methods ( Vigneshwaran et al, 2007 ; Haggag et al, 2019 ; Sadeghipour et al, 2020 ; Mosleh-Shirazi et al, 2021b ; Mujaddidi et al, 2021 ; Mussin et al, 2021 ; Rozhin et al, 2021 ). However, there are no organised data on the antifungal activity of biogenic AgNPs, nor on the mechanisms of action and resistance of fungi to AgNPs.…”

In recent years, an increase in multidrug-resistant fungal strains has been observed, which, together with the limited number of clinically available antifungal agents, highlights the need for the development of new antifungal agents. Due to the proven antifungal activity of silver nanoparticles (AgNPs), there is a growing interest in their use in the treatment of fungal infections. Nanoparticles are usually synthesised through a variety of physical and chemical processes that are costly and pollute the environment. For this reason, biogenic synthesis is emerging as an environmentally friendly technology and new strategies are increasingly based on the use of biogenic AgNPs as antifungal agents for clinical use. The aim of this review is to compare the antifungal activity of different biogenic AgNPs and to summarise the current knowledge on the mechanisms of action and resistance of fungi to AgNPs. Finally, a general analysis of the toxicity of biogenic AgNPs in human and veterinary medicine is performed.

This work provides the synthetic route for the arrangement of Fe 3 O 4 @Ag and α-Fe 2 O 3 @Ag core-shell nanoparticles (NPs) with cytotoxic capabilities. The production of Fe 3 O 4 @Ag and α-Fe 2 O 3 @Ag core-shell NPs was facilitated utilizing S. persica bark extracts. The results of Powder X-ray Diffraction (PXRD), Ultraviolet-visible (UV-Vis) spectroscopy, Vibrating Sample Magnetometry (VSM), Energy Dispersive X-ray (EDX) analysis, Field Emission Scanning Electron Microscopy (FESEM), and Transmission Electron Microscopy (TEM) supported the green synthesis and characterization of Fe 3 O 4 @Ag and α-Fe 2 O 3 @Ag NPs. The particle size was measured by the TEM analysis to be about 30 and 50 nm, respectively; while the results of FESEM showed that α-Fe 2 O 3 @Ag and Fe 3 O 4 @Ag particles contained multi-faceted particles with a size of 50-60 nm and 20-25 nm, respectively. The outcomes of VSM were indicative of a saturation magnetization of 37 and 0.18 emu/g at room temperature, respectively. The potential cytotoxicity of the synthesized core-shell nanoparticles towards breast cancer (MCF-7) and human umbilical vein endothelial (HUVEC) cells was evaluated by an MTT assay. α-Fe 2 O 3 @Ag NPs were able to destroy 100 % of MCF-7 cell at doses above 80 μg/mL, and it was confirmed that Fe 3 O 4 @Ag NPs at a volume of 160 μg/mL can destroy 90 % of MCF-7 cells. Thus, the applicability of the prepared nanoparticles of these nanoparticles in biological and medical fields has been demonstrated.
