“…To investigate the relation between the size of Ag-NPs and their bactericidal activities, the MIC values for each type (A, B and C) were measured using the micro-dilution method. Small Ag-NPs (type A) showed more pronounced bactericidal activities than types B and C. These results are similar to those reported by other investigators [57][58][59].…”

Green synthesis is an attractive and eco-friendly approach to generate potent antibacterial silver nanoparticles (Ag-NPs). Such particles have long been used to fight bacteria and represent a promising tool to overcome the emergence of antibiotic-resistant bacteria. In this study, green synthesis of Ag-NPs was attempted using plant extracts of Aloe vera, Portulaca oleracea and Cynodon dactylon. The identity and size of Ag-NPs was characterized by ultraviolet-visible spectrophotometer and scanning electron microscopy. Monodispersed Ag-NPs were produced with a range of different sizes based on the plant extract used. The bactericidal activity of Ag-NPs against a number of human pathogenic bacteria was determined using the disc diffusion method. The results showed that Gram positive bacteria were more susceptible than Gram negative ones to these antibacterial agents. The minimum inhibitory concentration was determined using the 96-well plate method. Finally, the mechanism by which Ag-NPs affect bacteria was investigated by SEM analysis. Bacteria treated with Ag-NPs were seen to undergo shrinkage and to lose their viability. This study provides evidence for a cheap and effective method for synthesizing potent bactericidal Ag-NPs and demonstrates their effectiveness against human pathogenic bacteria.

“…The wires were submerged in deionized water or in the presence of Pluronic® f127 at concentrations of 4.5 x 10 -4 , 1x10 -4 and 1x10 -5 M all these below the critical micellar concentration. A differential potential of 20 V was applied between the electrodes, changing the polarity every four minutes, holding the system under constant magnetic stirring, and at room temperature, as reported by Khaydarov and coworkers [16]. The potential was applied with a controlled potential power supply BK PRECISION® 1666 and the generated current was measured over time using a Fluke 45 Dual Display meter connected in series with the system.…”

“…In 1994, Reetz and Heilbig [13] published a work with a detailed description for the electrochemical synthesis, in which a metal plate was anodically dissolved and the resulting salt was reduced in a cathode, yielding particles stabilized with tetraalkylammonium salts which in turn meet electrolyte function. Other authors, had proposed electrochemical methods for the synthesis of AgNP using other types of electrolytes like ethanol:KNO 3 [14], poly(N-vinylpyrrolidone) [15] and deionized water [16]. For most applications of metallic nanoparticles it is required to make superficial modifications in order to promote the suspension stability.…”

Silver nanoparticles (AgNP) were synthesized by electrochemical method using high purity metallic silver in the presence of the surfactant Pluronic® f127. The synthesized nanoparticles were characterized using UV-Vis spectroscopy, Dynamic Light Scattering (DLS), X-Ray Dispersion Spectroscopy (XDS) and Scanning Electron Microscopy (SEM). The antimicrobial activity of AgNP was evaluated against Escherichia Coli. In presence of surfactant, the prepared nanoparticles led to a monomodal distribution with an average size less than 100 nm. The minimal inhibitory concentration (MIC) of the resulting suspension was evaluated using micro dilution method and the MIC results are satisfactory.
