“…A similar observation was also reported in previous studies. 25,26 Furthermore, the ratio between the intensity of the (111) peak and other peaks was high, suggesting that the (111) plane was the predominant growth direction in the crystal of AuNPs. 17 The FTIR measurements were taken to identify surface functional groups of the SG-AuNPs sample and dried SG fruit extract.…”

“…The formation of a single plasmonic band on the surface of each solution was observed. All samples showed the typical yellow color of the solution, 45 suggesting the formation of AgNPs in both formulations. 46 The plasmonic band was noticed after the synthesis, with peaks at about 393 and 385 nm, and was similar to the results reported by Dubas and Pimpan 47 for UV-visible analysis.…”

BACKGROUND: The objective of this work was the development of silver nanoparticles (AgNPs) coated with humic acid (HA) and their incorporation into an enamel for antifungal activity. AgNPs were synthesized by chemical reduction using sodium borohydride as a reducing agent and coated with HA. Uncoated AgNPs were synthesized as control. AgNPs and HA-AgNPs were characterized by ultraviolet-visible spectrophotometry, differential scanning calorimetry, dynamic light scattering, Fouriertransform infrared spectroscopy (FTIR), atomic force microscopy and X-ray diffraction (XRD). Size of AgNPs and HA-AgNPs was recorded within the nano range, showing HA-AgNPs' higher stability than non-coated particles by presenting a single plasmatic band around 400 nm.RESULTS: Thermal analysis showed conjugated endothermic peaks, which confirms the compatibility of HA-AgNPs. FTIR depicted absorptions between 1300 and 1000 cm −1 (C C, Ar H, respectively), demonstrating that HA is adsorbed onto AgNPs. Thermogravimetric analysis showed that HA does not alter the reduction in mass loss of AgNPs, while it was found by XRD that adding HA promoted the formation of more amorphous AgNPs. The effectiveness of HA-AgNPs was evaluated against three different fungal species. Minimum inhibitory concentration assays showed that ∼0.5 mmol L −1 AgNPs was able to inhibit dermatophyte species growth. HA-AgNPs were incorporated into a commercial enamel at a concentration of 8% and their organoleptic characteristics, drying time, centrifugation test and thermal stress were evaluated. Enamels with AgNPs kept their physicochemical properties over 21 days of storage. CONCLUSION: HA-AgNP nail polish is thus proposed as an innovative material for onychomycosis infections.

This study is devoted to the synthesis of King Orange peel essential oil in water nanoemulsions combined with nanosilver by ultrasonic method supported by mechanical stirring for antibacterial application. The samples were characterized by Gas chromatography-mass spectrometry (GC-MS), Ultraviolet-visible (UV-Vis), Transmission electron microscopy (TEM), and Dynamic light scattering (DLS) methods. According to the above-experimental results, it was found that the emulsions based on orange essential oil (without nanosilver) and the ones combined with nanosilver have the average particle size from 66.2 nm and 42.9 nm, respectively. The obtained nanoemulsions were also tested to examine their antibacterial ability against Escherichia coli (E. coli) by the disc diffusion method. It has been also found that nanoemulsions based on orange essential oil supported by nanosilver have the superior antibacterial ability, compared with individual components of the materials.
