“…Treatment of HCT-116 cells at 100 µg/mL revealed that Ag NPs had the maximum cytotoxicity followed by PS extract and Au NPs. PS Similar changes have also been reported on different cancer cell lines after treatment with Ag NPs, which were synthesized using plant extracts [32]. Some previous findings also show the cytotoxic effects of biologically synthesized Ag NPs against cancer cell lines [32,33].…”

Herbal medicines are widely used worldwide and much appreciated because of their fewer side effects and the ability to fight diseases at the root cause. Active ‘phyto’ ingredients require a scientific approach and a mechanism to distribute components at the target site for better therapeutic results. Nanotechnology, on the other hand, has created new hope for cancer treatment but is still far from being proven in clinical settings. This article combines a unique approach to synthesis with the use of Pleurotus sajor-caju, followed by microwave irritation of silver and gold nanoparticles that ensures the capping of the active phyto ingredient and further enhances the effects of nanomedicine to fight colon cancer, thus opening a new era of what we call herbonanoceutics. The article also compares the characteristics and properties of silver (Au) and gold (Ag) nanoparticles synthesized by an in house developed novel microwave-assisted rapid green synthesis method. The as-prepared Ag NPs and Au NPs were compared using ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), and energy dispersive spectroscopy (EDS). Our comparative study revealed that both assemblies display face-centred cubic structures (FCCs) and are nanocrystalline in nature. The advantage of the approach was that the sizes of gold and silver were identical in range with a similar distribution pattern. This has helped us to study the activity against colon cancer cell line (HCT-116) without incoherence since size plays a key role in the application. More specifically, morphological changes, cell viability, the production of reactive oxygen species (ROS) and the fragmentation of DNA have been further reported to assess better the results obtained with the two metals. Our results suggest that the newly adopted synthesis method may ensure the dual benefits from phyto ingredients which further enhances the effectiveness of advanced nanomedicine.

“…According to the image, the largest number of particles in this Figure has an average size of about 20 nm. The result of the SEM image is very similar to the previous results [19]. TEM results Figure 9 shows the image of the transmitted electron microscope of silver NPs by applying all optimized conditions.…”

Here, green synthesis of silver nanoparticles (NPs) using aqueous extract of Scrophularia Striata was demonstrated. In order to obtain the best formation conditions of NPs, different physicochemical parameters such as volume of the extract, silver ion concentration, temperature and reaction time were studied. Synthesized resultant NPs were characterized using UV, SEM, TEM, EDX, XRD, FT-IR and DLS analyses. A color change to brown after adding the extract to the silver nitrate solution was observed which indicated the formation of silver NPs. The synthesized silver NPs by Scrophularia Striata extract showed the highest absorbance at 426 nm. Plants have been used as stabilizing and reducing agents for NPs, due to their antioxidant properties and many secondary compounds.

“…Moreover, while sputtering power increases, the (111) peak intensity becomes stronger as shown in Figure 1(a). This implies an increase in crystallinity and grain size, with (111) plane having the lowest surface energy [13,15,18]. The grain size of the silver film is an important indicator of the crystallization quality, which was calculated using the Scherrer formula.…”

We present an investigation into the pseudo-capacitive energy storage potential of silver (Ag) and silver oxide (Ag 2 O) thin film electrode materials prepared by reactive magnetron sputtering. The growth mode and morphology of the prepared films were investigated using the scanning electron microscope (SEM), which reveals columnar growth structure and microporous sites. The stoichiometry and oxidation states of the silver oxide films were monitored with X-ray diffraction analysis (XRD), X-ray photoelectron spectroscopy (XPS) and Fourier transform infra-red spectroscopy (FTIR). The XRD results reveal the nanocrystalline nature of the silver and silver oxide thin films with peak intensities indexed at (111) planes. Static and dynamic Contact angle measurements were used to probe the penetration of the aqueous NaCl electrolyte into the pores in the prepared silver and silver oxide films, with surface wettability of all (Ag) and (Ag 2 O) thin films hydrophilic in nature, which is vital for a good electrochemical performance. The Faradaic redox reactions, capacitance and the charge discharge of the films when exposed to the NaCl electrolyte, were monitored with cyclic voltammetry and chronopotentiometry charge-discharge. Results show that Silver and silver oxide
