“…It has previously been shown that the green synthesis of AgNPs in darkness does not produce characteristic SPR peaks [74] even after prolonged reaction times [75]. Moreover, light of different types and spectra, such as UV treatment, sunlight irradiation, and fluorescent light exposure, also promoted the bioinspired synthesis of metal nanoparticles [76][77][78]. Flash light radiation promoted the production of silver, gold, and bimetallic nanoparticles in an energy density-dependent manner [79].…”

The present study reports a green chemistry approach for the rapid and easy biological synthesis of silver (Ag), gold (Au), and bimetallic Ag/Au nanoparticles using the callus extract of Lithospermum erythrorhizon as a reducing and capping agent. The biosynthesized nanoparticles were characterized with ultraviolet-visible (UV-Vis) spectroscopy, X-ray diffraction (XRD) analysis, and transmission electron microscopy (TEM). Our results showed the formation of crystalline metal nanostructures of both spherical and non-spherical shape. Energy dispersive X-ray (EDX) spectroscopy showed the characteristic peaks in the silver and gold regions, confirming the presence of the corresponding elements in the monometallic particles and both elements in the bimetallic particles. Fourier-transform infrared (FTIR) spectroscopy affirmed the role of polysaccharides and polyphenols of the L. erythrorhizon extract as the major reducing and capping agents for metal ions. In addition, our results showed that the polysaccharide sample and the fraction containing secondary metabolites isolated from L. erythrorhizon were both able to produce large amounts of metallic nanoparticles. The biosynthesized nanoparticles demonstrated cytotoxicity against mouse neuroblastoma and embryonic fibroblast cells, which was considerably higher for Ag nanoparticles and for bimetallic Ag/Au nanoparticles containing a higher molar ratio of silver. However, fibroblast migration was not significantly affected by any of the nanoparticles tested. The obtained results provide a new example of the safe biological production of metallic nanoparticles, but further study is required to uncover the mechanism of their toxicity so that the biomedical potency can be assessed.

“…The antimicrobial activity of the synthesized AgNPs against two common human pathogens is tested by the standard broth dilution method [26]; the Gram-negative Escherichia coli (ATCC25922) and Gram-positive Staphylococcus aureus (ATCC25923). A single colony of each bacteria was initially cultured in 5 ml MH broth in an incubator shaker at 37 C and 200 rpm for 4 h. The turbidity of the bacterial culture was adjusted equal to 0.5 McFarland standard or 1 Â 10 8 colonyforming units/ml (CFU/ml).…”

Green synthesis of silver nanoparticles (AgNPs) provides the alternative method with cost effectiveness and the eco-friendly process by using natural biomolecules as reducing and stabilizing agents. Alternative to the most studies of plant extracts, this work demonstrated a use of egg extract of apple snail (Pomacea canaliculata) for an eco-friendly production of AgNPs. The extract contained at least six proteins with the molecular weight in a range of 24-65 kDa that exhibited the reducing activity. The dispersive AgNPs were produced in the reaction containing only the extract and silver nitrate, as determined by the characteristic surface plasmon resonance peak of silver at 412 nm. The synthesized AgNPs were spherical with the average diameter of 9.0 ± 5.9 nm. The X-ray diffraction pattern and selected area electron diffraction (SAED) analyses confirmed the face-cubic centre (fcc) unit cell structure of AgNPs. The synthesized AgNPs exhibited the antibacterial activity against both Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. Results of this work clearly showed the potential use of the egg extract of apple snail for a green synthesis of small size AgNPs exhibiting the antibacterial activity.

“…Nanoparticles are extensively used in biotechnological, industrial, and medical applications. Although synthesis of nanoparticles is a very sensitive process and requires precaution, nanoparticles have attracted considerable attention for their impressive character and application, which differ greatly from bulk materials (Hu and Hsieh, ; Khamhaengpol and Siri, ). Silver nanoparticles (AgNP), which are effective antibacterial and antifungal agents, show a high binding affinity with organic materials (Gannimani et al, ; Tyliszczak et al, ).…”

The surface parameters of some cationic surfactants having different hydrophobic alkyl chains were assessed in aqueous solution using different techniques; surface tension, ultraviolet‐Visible (UV–Vis) spectroscopy, and conductivity measurements. The obtained critical micelle concentration (CMC) for N‐(2‐((3,4‐dimethoxybenzylidene)amino)ethyl)‐N,N‐dimethyloctan‐1‐aminium bromide (DBAO), N‐(2‐((3,4‐dimethoxybenzylidene)amino)ethyl)‐N,N‐dimethyldodectan‐1‐aminium bromide (DBAD), and N‐(2‐((3,4‐dimethoxybenzylidene)amino)ethyl)‐N,N‐dimethylhexadectan‐1‐aminium bromide (DBAH) in aqueous solution using three techniques are nearly the same. Increasing the hydrophobic chain length enhances micelle formation. Raising the solution temperature from 25 to 65 °C also shows the same trend. The thermodynamic calculations outlined the adsorption propensity of the surfactants at the surface compared to their affinity to form micelles. Both micellization and adsorption processes are enhanced with both the hydrocarbon elongation and with raising the solution temperature. The effect of the surfactant tail on the preparation process of the silver nanoparticles (AgNP) was assessed and confirmed using transmission electron microscope (TEM), dynamic light scattering (DLS), and UV–Vis spectra. Increasing the surfactant tail leads to a smaller particle size with a narrow distribution. The stability of the prepared AgNP is enhanced with hydrophobic surfactant tail elongation as proved with increasing the zeta‐potential of the prepared AgNP colloid. The foaming power, interfacial tension, and emulsification stability of the DBAO, DBAD, and DBAH surfactants were determined. The DBAO, DBAD, and DBAH surfactants showed good antimicrobial activities against both bacteria (Gram positive and negative) and fungi, which have been enhanced because of incorporation of AgNP.
