“…These FTIR spectrum results were very similar to the previous researcher studied about the functional groups presence in aqueous ASL extract [31]. Based on the acquired spectrum, the active groups that play a role in the reduction and the stabilization of AuNPs are phenolic, organosulfur compounds, amino acids, carboxylic groups, and proteins [32].…”

Gold nanoparticles (AuNPs) have been successfully prepared by green synthesis method using aqueous extract of garlic with the Latin name of Allium sativum L. (ASL) as a reducing and stabilizing agents. Identification of active compounds in aqueous ASL extract was conducted by phytochemical analysis and Fourier transform infrared (FTIR) spectroscopy, while the synthesized AuNPs were characterized using UV-Vis spectrophotometer and transmission electron microscopy-selected area electron diffraction (TEM-SAED). The AuNPs formation was optimized at aqueous ASL extract concentration of 0.05%, HAuCl4 concentration of 2.0×10 -4 M, and pH of 3.6. The optimized AuNPs was characterized using TEM, and has a spherical shape with particle size of 15±3 nm. The particles were also stable up until one month. The synthesized AuNPs has been studied its interaction with melamine, and showed the optimum pH of interaction at 3.6.

“…To overcome this, photo-assisted biosynthesis of Ag and AuNPs using many plants has been qualitatively investigated [28]. The sunlight irradiation technique has been formerly reported for the synthesis of nanoparticles using few plant materials such as Allium sativum [29], Andrachnea chordifolia [30], Piper betle [31], Bacillus amyloliquefaciens [32] and Achyranthus aspera [33]. Apart from plant materials, dendrimers and starch are also used as reducing/stabilizing agents in the sunlight-induced synthesis of nanoparticles [34,35].…”

Photobiological synthesis of noble metal nanoparticles using Hydrocotyle asiatica and application as catalyst for the photodegradation of cationic dyes

Solar light induced photo catalysis by plasmonic nanoparticles such as Au and Ag is an important field in green chemistry. In this study an environmental benign method was investigated for the rapid synthesis of colloidal Ag and AuNPs using the extract of Hydrocotyle asiatica, as a reducing and stabilizing agent under sunlight irradiation. The nanoparticles were formed in few seconds and were characterized by UV-Vis., FT-IR, TEM, EDAX, XRD, DLS and Zetasizer. The nanoparticles were stable in aqueous solution for more than 6 months. TEM analysis established that the Ag and AuNPs were predominantly spherical with average size of 21 and 8 nm, respectively. The flavonoids and glycosides from the extract of H. asiatica were proved to be responsible for the reduction and capping through FT-IR analysis. The antimicrobial studies of AgNPs showed effective inhibitory activity against the clinical strains of gram-negative and positive bacteria. The localized surface plasmon resonance of AgNPs was used for the photo-driven degradation of cationic dyes (malachite green and methylene blue). Thus, this green technique can be used for bulk production of AgNPs, and thus prepared nanoparticles may be used for removal of dyes from effluent. Graphical Abstract

“…In this study, autoclaving method (thermal treatment) was adopted as a pseudo-synthetic route to produce sterile silver nanoparticles that are completely free from viruses, bacteria, and spores, and these sterile silver nanoparticles may find biological applications. Earlier studies report the use of plant leaf extracts, seed extracts, naturally occurring gums, and living organisms for green synthesis of AgNPs (ElRafie et al 2010;Lori Rastogi and Arunachalam 2011).…”

Eco-friendly green synthesis of silver nanoparticles using salmalia malabarica: synthesis, characterization, antimicrobial, and catalytic activity studies

An economically viable and ''green'' process has been developed for the synthesis of silver nanoparticles (AgNPs) with an average size of 7 nm using non-toxic and renewable salmalia malabarica gum (SMG) as reducing and capping agent without using any chemical reducing agent. The effect of various parameters such as concentration of SMG and silver nitrate and reaction time for the synthesis of AgNPs was studied. The synthesized AgNPs are systematically characterized by UV/Vis spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction and Transmission electron microscopy. The resultant SMG-capped AgNPs are highly stable and had significant antibacterial action on both Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). The catalytic action of the SMG-capped AgNPs to initiate the reduction of 4-nitrophenol (4-NP) in the presence of NaBH 4 has also been reported. The kinetics of the reaction was found to be of pseudo-first-order with respect to the 4-NP.
