“…The present research work describes the synthesis of AgNPs using the ethanolic leaf extract of Curvibacter lanceolatus, Dracocephalum parviflorum, Eucalyptus citriodora, Melaleuca cajuputi, Rhodomyrtus tomentosa, Syzygium campanulatum, and Xanthostemon chrysanthus where the SPR band appeared at 420, 417, 418, 458, 434, 462, and 424 nm, respectively. It is known that the SPR band is sensitive to the discrete dipole approximation considering different shapes and sizes of the particles formed [18]. Similar results were observed on the synthesis of AgNPs using the leaf extract of Datura stramonium where it was found that a narrow SPR peak appeared at 444nm which may be ascribed to the formation of isotropic spherical AgNPs.…”

This review is based on the synthesis of silver nanoparticles (AgNPs) using a green approach which is biofabricated from various medicinal plants. AgNPs were prepared from the various parts of the plants such as the flowers, stems, leaves, and fruits. Various physiochemical characterizations were performed using the ultraviolet (UV)-visible spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction spectroscopy, transmission electron microscopy, and energy dispersive spectroscopy. AgNPs were also used to inhibit the growth of bacterial pathogens and were found to be effective against both the Gram-positive and Gram-negative bacteria. For the silver to have antimicrobial properties, it must be present in the ionized form. All the forms of silver-containing compounds with the observed antimicrobial properties are in one way or another source of silver ions. Although the antimicrobial properties of silver have been known, it is thought that the silver atoms bind to the thiol groups in enzymes and subsequently leads to the deactivation of enzymes. For the silver to have antimicrobial properties, it must be present in the ionized form. The study suggested that the action of the AgNPs on the microbial cells resulted into cell lysis and DNA damage. AgNPs have proved their candidature as a potential antibacterial against the multidrug-resistant microbes. The biological agents for synthesizing AgNPs cover compounds produced naturally in microbes and plants. Reaction parameters under which the AgNPs were being synthesized hold prominent impact on their size, shape, and application. Silver nanoparticle synthesis and their application are summarized and critically discussed in this review.

“…The green methods that have been used so far have specifically deployed bacteria and fungi for synthesizing nanoparticles, but using these organisms involve tedious processes and require careful cell culture preparation . Therefore, numerous biomimetic approaches are being explored for the synthesis of AgNPs using plants such as Callistemon lanceolatus, Xanthostemon chrysanthus, Cassia auriculata, Andean blackberry, Allium sativum and Ficus panda . Plant‐mediated synthesis offers a unique combination of advantages including high resource availability, safe handling, biocompatibility, and a wide variety of metabolites contained in plants that may help in forming AgNPs.…”

In the current work, we followed a green chemistry route to prepare and characterize the silver nanoparticles (AgNPs) using Syzygium aromaticum (clove) extract at room temperature. Suitably, the clove extract acted as a reducing agent as well as a capping agent, and these reactions occurred rapidly. The formation of the AgNPs was confirmed by the observation of the distinct absorption peak at a wavelength of 418 nm using ultraviolet–visible (UV–Vis) spectroscopy, and a morphological study confirmed the uniform distribution of the optimally spherical nanoparticles. Fourier transform infrared spectroscopy (FTIR) results indicated the methoxy and allyl functional groups of eugenol of the clove extract to be responsible for the bioreduction of silver ions and for the stabilization of the resulting nanoparticles (flavonoids). We also found the AgNPs to be effective catalysts of the degradation of three pollutant organic dyes viz., 4‐nitrophenol, methylene blue and rhodamine B, in the presence of excess NaBH4. The antibacterial and antifungal activities of the bio‐synthesized AgNPs were also explored. Overall, the results suggested the potential use of clove extract as a resource for the synthesis of AgNPs having a broad range of possible commercial and biomedical applications.

“…(Fig 1) The brown colour formation is the characteristic of AgNPs formation and changes in colour due to size of nanoparticles also depends on their surface plasmon resonance (SPR) 19,20 . It is an efficient and rapid method, which was very well explained by other researches who worked with different plant systems 21,22 . In the present results are in conformity with Bonde et al 23 who reported the formation of AgNPs within 1hr of incubation.…”

In the present study, the potential of aqueous whole plant extract of Croton sparsiflorus for biosynthesis of silver nanoparticles (AgNPs) was evaluated. The formation of AgNPs was confirmed by color changes and UV- Visible spectroscopy, which showed absorbance maxima peak at 417nm. The scanning electron microscope (SEM) analysis confirmed the particle size and x-ray diffraction (XRD) confirmed the crystalline character of AgNPs. AFM analysis also confirmed the surface morphology of synthesized AgNPs. Fourier transform infrared (FTIR) authorized the presence of alcoholic and phenolic groups played an important reduction role in the synthesis process. It shows the antibacterial efficiency against gram negative bacteria, Klebsiella pneumoniae and Salmonella paratyphi. From the results, it is suggested that green synthesized AgNPs could be used effective in future biomedical engineering. Keywords: Croton sparsiflorus, Green synthesis, Silver nanoparticles, X-ray diffraction, Antibacterial activity.
