Biogenic Nanosilver as a Potential Antibacterial and Antifungal Additive to Commercially Available Dish Wash and Hand Wash for an Enhanced Antibacterial and Antifungal Activity Against Selected Pathogenic Strains

Abstract

In the present study, biogenic silver nanoparticles rapidly synthesized using leaf extract of Rosa indica -wichuriana hybrid Francois guillot were investigated for their potential use as a antibacterial and antifungal additive to commercially available dish wash and hand wash. UV-vis spectrophotometer, Powder X-ray diffraction, FTIR spectroscopy, HrTEM and EDX analysis were used to characterize the synthesized silver nanoparticles. UV-vis spectrum analysis showed the surface plasmon peak at 427 nm. From high resolution transmission electron microscopy (HrTEM) analysis, the size of the silver nanoparticles was determined to be 15-25 nm. The synergy of biogenic silver nanoparticles and commercially available dish wash and hand wash showed enhanced antibacterial and antifungal activity against selected pathogenic strains Escherichia coli, Staphylococcus aureus, Micrococcus luteus, Klebsiella pneumoniae, Candida albicans, C. tropicalis, C. krusei.

Free radical scavenging activity of zinc oxide nanoparticles biosynthesised using Aspergillus carneus

“…The band detected at 2857.99 cm −1 was described [32] as C–H stretching corresponding to aromatic mode arises from aromatic amino acids. Other distinct peaks were recorded 2362.37, 1423.21 and 1238.08 cm −1 corresponding to –COO [33], –CH 3 bending bonds [34] and C–C stretching vibration of alkanes [26], respectively. In addition, the weak peak with a wavelength 765.60 cm −1 was suggested as –CH by [35].…”

Silver Nanoparticles: Therapeutical Uses, Toxicity, and Safety Issues

“…In addition, many species have been reported to be resistant to many commonly used antifungal agents. According to Rajarathinam and Kalaichelvan, AgNPs can be the appropriate agents for the control of three Candida species, namely, C. albicans , C. tropicalis , and C. krusei . Further, they also demonstrated its application as additive in commercially available dish and hand wash. Another study by Monteiro et al has also proved the potential of AgNPs against C. albicans and C. glabrata .…”

“…Several studies have reported potent antifungal activity of AgNPs against pathogenic fungi, and most of them have been focused on the effect of AgNPs on the Candida species (Chwalibog et al 2010;Monteiro et al 2011;Nasrollahi et al 2011;Hwang et al 2012;Rajarathinam and Kalaichelvan 2013). However, only few studies have been performed to assess the effects of AgNPs on dermatophytes.…”
