“…The IR spectra of purified metal NPs (Au, Ag, and Au–Ag NPs) and PE closely resembled each other, which confirmed the presence of phytomolecules as surface ligands on the NP surface. Analysis of these spectra showed the presence of phenolic and flavonoid groups, which are responsible for NP formation [ 41 ]. The IR spectrum of PE exhibited a broad absorption between 3791 and 3440 cm −1 and sharp bands at ~2929 and 2850 cm −1 , which were attributed to the stretches of the O–H and C–H groups.…”

Plant extract of Pulicaria undulata (L.) was used as both reducing agent and stabilizing ligand for the rapid and green synthesis of gold (Au), silver (Ag), and gold–silver (Au–Ag) bimetallic (phase segregated/alloy) nanoparticles (NPs). These nanoparticles with different morphologies were prepared in two hours by stirring corresponding metal precursors in the aqueous solution of the plant extracts at ambient temperature. To infer the role of concentration of plant extract on the composition and morphology of NPs, we designed two different sets of experiments, namely (i) low concentration (LC) and (ii) high concentration (HC) of plant extract. In the case of using low concentration of the plant extract, irregular shaped Au, Ag, or phase segregated Au–Ag bimetallic NPs were obtained, whereas the use of higher concentrations of the plant extract resulted in the formation of spherical Au, Ag, and Au–Ag alloy NPs. The as-prepared Au, Ag, and Au–Ag bimetallic NPs showed morphology and composition dependent catalytic activity for the reduction of 4-nitrophenol (4-NPh) to 4-aminophenol (4-APh) in the presence of NaBH4. The bimetallic Au–Ag alloy NPs showed the highest catalytic activity compared to all other NPs.

Advancements in metal nanoparticle synthesis using plant extracts and their anticancer activity have received significant attention in recent years. The green approach for the synthesis of gold nanoparticles (AuNPs) using leaf extract of Sasa borealis is reported in this study. Synthesis of AuNPs was performed at 50 °C, and nanoparticle formation was observed after 20 min incubation. AuNPs formation was confirmed by the UV-visible spectrum peak at 542 nm. The synthesized AuNPs were oval, spherical with sizes around 10-30 nm observed using the transmission electron microscope. Energy dispersive X-ray analysis was utilized for the detection of elemental compound. The face centered cubic structure was confirmed by X-ray diffraction pattern. The reduction of tetrachloroauric acid into AuNPs by the phytochemical compounds of S. borealis extract was determined by Fourier transform infrared spectroscopy and the presence of biomolecules was studied by GC-MS. The synthesized AuNPs was tested for toxic effect on HEK293 cells and anticancer activity on AGS cells by WST-1 assay. Condensation or fragmentation is a characteristics of apoptosis, which was confirmed by 4,6-diamidino-2-pheynylindole dihydrochoride (DAPI) staining. The S. borealis-mediated AuNPs have good activity as an anticancer agent and it will be beneficial in cancer therapeutics.

“…In this regard, various researchers have tried to define a steady process for the synthesis of AgNPs to achieve desired homogeneity, related to size, shape and morphology. Various researchers have experimented to get homogeneity, either through modifying parameters of bio-fabrication process or by varying and extracting the phyto-compounds [31,33,38,39]. Reaction parameters like the ratio of plant extract to metal precursor, precursor and plant extract concentration, reaction exposure time, pH, reaction temperature, solvent system used and chemical composition of the plant extract were studied and evaluated to determine the homogeneity of the AgNPs (Figure 2).…”

In recent years, fabrication of AgNPs via plant extracts has gained much attention because of being environmentally friendly, non-hazardous and cost effective. The bio-fabrication of AgNPs using plant extracts as reducing, capping and stabilizing agents includes simpler, safer, less-toxic and energy efficient. AgNPs have been widely applied in numerous fields due to their bio-compatibility, multifunctionality, solubility, high stability, therapeutic and adhesive properties. This review focuses on the advantages of AgNPs synthesis using plant extracts and its applications in various fields for the betterment of mankind and environment with numerous examples and also highlights on explaining possible fundamental mechanisms involved in antimicrobial and anticancer activities of plant extract synthesized AgNPs.
