Antifungal Activity of Silver Nanoparticles Obtained by Green Synthesis

Abstract

Silver nanoparticles (AgNPs) are metal structures at the nanoscale. AgNPs have exhibited antimicrobial activities against fungi and bacteria; however synthesis of AgNPs can generate toxic waste during the reaction process. Accordingly, new routes using non-toxic compounds have been researched. The proposal of the present study was to synthesize AgNPs using ribose as a reducing agent and sodium dodecyl sulfate (SDS) as a stabilizer. The antifungal activity of these particles against C. albicans and C. tropicalis was also evaluated. Stable nanoparticles 12.5 ± 4.9 nm (mean ± SD) in size were obtained, which showed high activity against Candida spp. and could represent an alternative for fungal infection treatment.

Biosynthesis of silver nanoparticles using Caesalpinia ferrea (Tul.) Martius extract: physicochemical characterization, antifungal activity and cytotoxicity

“…Biological methods of synthesis of nanoparticles using microorganisms (Castro-Longoria, Vilchis-Nestor & Avalos-Borja, 2011; Geronikaki et al, 2013; Xue et al, 2016), enzymes (Jacometo et al, 2015), and plant or plant extracts (Iravani, 2011; Mallmann et al, 2015; Kubyshkin et al, 2016; Shaik et al, 2017) have been suggested as ecofriendly alternatives to chemical and physical methods. Using plant extracts for synthesis of nanoparticles can be advantageous over other biological processes by eliminating the elaborate process of maintaining cell cultures (Iravani, 2011).…”

Nanosilver: new ageless and versatile biomedical therapeutic scaffold

“…Stable nanoparticles of size 12.5±4.9 nm (mean ± SD) were obtained, which presented high activity against Candida spp. 261 The spherical and polydispersed AgNPs, ranging in size from 4 to 36 nm and 8 to 60 nm, respectively, were applied against superficial mycoses caused by T. rubrum, Malassezia furfur, C. albicans, C. glabrata and C. krusei were exposed to spherical nanoparticles (19 nm) with positive surface charge. The MIC50 values were 0.1-l g mL −1 AgNPs, and minimum fungicidal concentration (MFC) values were 0.25 and 0.5 g mL −1 for C. glabrata and C. krusei, respectively.…”

A Review on Indian Tribal Plants and Their Biogenic Properties

“…Due to its antifungal property, silver nanoparticles (AgNPs) are extensively used to prevent biofouling on the surface of the cathode [24]. AgNPs has gained boundless interest due to their unique properties such as chemical stability [25,26], good conductivity [27,28], catalytic [29] and most important antibacterial [30,16] antifungal [31], antiviral, [32][33][34] and anti-inflammatory activities [35][36][37]. In addition, silver has occupied a major place in consumer products where some of the products are toothpaste, as an engineered nanomaterial get exposed to environment and makes available for humans through drinking water, humidifiers, and through soil [38,39], it is used in clothing to protect from body odor, medicine such as acne creams and sulfadiazine creams, cosmetics, baby pacifiers, washing machine, and electronic gadgets [40].…”
