“…Therefore, the content of AgCl NPs below the antibacterial threshold can reduce the cytotoxicity of the hydrogel, which is availed to the reparation of the damaged skin. For the purpose of antibacterial as well as inhibiting the adhesion and proliferation of cell-like organisms, hydrogel AS75 can be used as a benchmark to achieve the dual role of antibacterial and the inhibition of cell-based bio-adhesion [38,39].…”

Silver nano-particles (AgNPs)-filled antibacterial materials have been widely employed in the fields of biology and biomedicine. However, AgNPs have shown obvious cytotoxicity. Hence it is more reasonable to use silver chloride nanoparticles (AgCl NPs) to prepare antibacterial materials due to the slow release of silver ions created by AgCl NPs formed in the chitosan. In this experiment, a useful antibacterial hydrogel for skin repairation was prepared by exploring the relationship between AgCl NPs and cytotoxicity. It is worth noting that the crosslinked network structure was successfully obtained in an antibacterial AgCl/PVA (Polyvinyl alcohol)/PEG (Polyethylene glycol)/CS (Chitosan) hydrogel materials by the hydrothermal method. In detail, the dynamic particle size distribution of AgCl NPs was relatively uniform, which is analyzed by a dynamic light scattering (DLS). The internal structure of the lyophilized hydrogel showed obvious porous structure, indicating that the hydrogel had high water content. The result of X-ray photoelectron spectroscopy (XPS) confirmed the existence of a silver element. The release concentration of silver ions was analyzed by inductively coupled plasma (ICP) to study the effect of silver ions release concentration on the antibacterial activity and cytotoxicity of hydrogel. The results show that the lower concentration of silver ions can make the hydrogel have good antibacterial activity and low cytotoxicity. The bacteriostatic rate of the antibacterial hydrogel was over 90%. Simultaneously, the mechanical properties test shows that the hydrogel has good mechanical properties, which can be widely used as an antibacterial material.

“…The formation of AgCl NPs is usually associated with the biogenic synthesis of Ag nanoparticles using plant extracts and microorganisms (Durán et al, 2016). Other researchers have reported similar results (Chankaew et al, 2018;Feiziet al, 2018;Okaiyeto et al, 2019). The AgCl formation could be due to the reaction among Ag + from AgNO 3 , and the Cl − ions from the aqueous leaf extract of L. tridentata.…”

Green synthesis of silver nanoparticles (AgNPs) from plant extracts is simple, fast and environmentally friendly. In this study, an aqueous extract of fresh leaves from Larrea tridentata was evaluated as a possible source of reducing and stabilizing agents to obtain AgNPs. The synthesized nanoparticles were characterized by X-ray diffraction, revealing the metallic nature of Ag nanoparticles. Transmission electron microscopy (TEM) studies showed spherical nanoparticles with sizes below 28 nm. Furthermore, its bactericidal effect against Clavibacter michiganensis subsp. michiganensis (Cmm) infection in tomato plants was determined. Forty-two days after inoculation with Cmm, the disease incidence in plants with AgNPs did not exceed 20% at 50 mg L −1 , and it also reduced disease severity by 36%, which correlates with the inhibition of bacterial growth in the tissue (up to 95%). The physiological analysis also showed the growth-promoting effect of AgNPs in diseased plants, increasing shoot length (22.1%) and root dry weight (25.73%) compared with the pathogenic control. Congruently, AgNPs increased enzyme activity for CAT, APX, POD, and total phenol and flavonoid concentrations in the leaves. Slower symptom development and reduction in bacterial growth in AgNPs-treated plants could be due to this bactericidal activity and the induction of an antioxidative protection system.

“…The modified Gompertz model has been described by Zwietering et al [70] and adapted by Li et al [69] and other authors [71][72][73][74][75][76][77][78] as a model that adjust the growth curves and where A is the cell number expressed as OD 540 (S. aureus and E. coli) and OD 600 (C. albicans), μ is the growth rate at the exponential phase and e is the exponential e 1 , is the lag phase. We have adjusted our growth kinetic using a software origin 9.1 to analyze the effects over S. aureus, E. coli, and C. albicans of the three agents AuNPs, AgNPs, and Au@AgNPs.…”

Au@Ag Core@Shell Nanoparticles Synthesized with Rumex hymenosepalus as Antimicrobial Agent

et al. 2021

In this work, we used a sequential method of synthesis for gold–silver bimetallic nanoparticles with core@shell structure (Au@AgNPs). Rumex hymenosepalus root extract (Rh), which presents high content in catechins and stilbenes, was used as reductor agent in nanoparticles synthesis. Size distribution obtained by Transmission Electron Microscopy (TEM) gives a mean diameter of 36 ± 11 nm for Au@AgNPs, 24 ± 4 nm for gold nanoparticles (AuNPs), and 13 ± 3 nm for silver nanoparticles (AgNPs). The geometrical shapes of NPs were principally quasi-spherical. The thickness of the silver shell over AuNPs is around 6 nm and covered by active biomolecules onto the surface. Nanoparticles characterization included high angle annular dark field images (HAADF) recorded with a scanning transmission electron microscope (STEM), Energy-Dispersive X-ray Spectroscopy (EDS), X-Ray Diffraction (XRD), UV–Vis Spectroscopy, Zeta Potential, and Dynamic Light Scattering (DLS). Fourier Transform Infrared Spectrometer (FTIR), and X-ray Photoelectron Spectroscopy (XPS) show that nanoparticles are stabilized by extract molecules. A growth kinetics study was performed using the Gompertz model for microorganisms exposed to nanomaterials. The results indicate that AgNPs and Au@AgNPs affect the lag phase and growth rate of Escherichia coli and Candida albicans in a dose-dependent manner, with a better response for Au@AgNPs
