The use of nanoparticles in anti-microbial materials and their characterization

Abstract

Anti-microbial materials have multiple applications in medicine, industry and commercial products. Recent research has proposed the use of nanoparticles in a range of materials, as some metal nanoparticles are known to possess antibacterial properties. The development of such materials presents both the chemist and the biologist with the challenge to effectively choose analytical methods that provide relevant information regarding these materials. Herein, we describe techniques for the characterization of the nanoparticle-doped materials and methods for the determination of their efficacy against biofilm formation.

Biogenic synthesis and spectroscopic characterization of silver nanoparticles using leaf extract of Indoneesiella echioides: in vitro assessment on antioxidant, antimicrobial and cytotoxicity potential

“…In combination with metallic nanoparticles such as copper, zinc and silver are most promising because of their biomedical properties. However, the mechanism and mode of action are still a matter of debate, due to their superior antimicrobial properties against bacteria, viruses and fungi comparing with standard antibiotics (Rai et al 2009;Weir et al 2008). Green-prepared silver nanoparticles (SNPs) have the physical properties of a larger specific surface area, smaller in size and high dispersion (Sharma et al 2009).…”

Innovative biofilm inhibition and anti-microbial behavior of molybdenum sulfide nanostructures generated by microwave-assisted solvothermal route

“…Under this approach, nanomaterial can be applied as an agent that inhibits the formation of biofilms without actually killing the microbial cells. Biofilm growth can cause infection (Bjarnsholt et al 2010) and has detrimental effects on various materials and equipments like medical devices, implants, and food-processing equipments, thereby causing enormous economic and health-related damages (Weir et al 2008).…”

Antibacterial Composite Layers on Ti: Role of ZnO Nanoparticles

“…The primary advantage of such antibacterial coatings is the release of the antibacterial agent at the site of implantation, minimizing the risk of concentrations being reached that could cause harmful side effects in other parts of the body. Recently, nontraditional antibiotic agents have been of tremendous interest in overcoming resistance that is developed by several pathogenic microorganisms against most of the commonly used antibiotics [8,9]. Especially, silver nanoparticles have proven their effectiveness for preventing bacterial adhesion and biofilm formation [10].…”
