Fabrication of nanofibers with antimicrobial functionality used as filters: protection against bacterial contaminants

Abstract

A comparative study of antimicrobial activity is done using three different electrospun nanofibers namely-CA, PAN, and PVC used as control and with various amounts of AgNO(3) being treated with UV-irradiation leading to the enhancement of silver nanoparticles. DMF is used as the common solvent which helps to undergo spontaneous slow reduction at room temperature to form silver nanoparticles followed by UV-irradiation using a 400 W source. The time required for the formation of silver nanoparticles is short and they are more or less well dispersed with few such aggregates. The presence of silver nanoparticles is confirmed using various characterization techniques. The antimicrobial activity is studied using nanofibers with fabricated functionality.

Green synthesis of silver nanoparticles using leaf extract of medicinally potent plant Saraca indica: a novel study

“…Nanoparticles present a higher surface to volume ratio with decreasing size (Singh et al 2010). The biological effectiveness and value of nanoparticles increase proportionally with an increase in the specific surface area which is due to the increase in their surface energy and catalytic reactivity and also due to changes in physical, mechanical, optical and electromagnetic properties (Pradeep and Anshup 2009;Choi et al 2007;Reddy et al 2008;Okuda et al 2005;Lala et al 2007). Nanoparticles are synthesized using different methods and more routinely used chemical methods (Sundarrajan et al 2010;Thakkar et al 2010).…”

Regenerable Antibacterial Cotton Fabric by Plasma Treatment with Dimethylhydantoin: Antibacterial Activity against S. aureus

“…Antibacterial finishing is of enormous importance in the textile industry because fibres are susceptible to microorganisms, including bacteria and fungi, which are nourished by sweat, sebum, and food stains, as well as the fibres themselves [1][2][3][4]. These microorganisms can cause odor, staining, deterioration of textiles, and infection, allergies, and diseases.…”

Treatment of Air Filters Using the Antimicrobial Natural Products Propolis and Grapefruit Seed Extract for Deactivation of Bioaerosols

“…To inactivate this accumulation of microorganisms and to minimize reentrainment of viable bioaerosols, antimicrobial treatment of air filters is necessary. Various antimicrobial agents have been investigated for use in air filters, including silver nanoparticles (Jin et al 2007;Lala, et al 2007), iodine (Lee et al 2009), and carbon nanotubes (Brady-Est evez et al 2008, Jung et al 2011a.…”
