Antimicrobial properties and application Silver Nanoparticles in food industry

Silver nanoparticles have gained major interest because of their wide potential applications. Silver nanoparticles cause less toxicity to human health but, highly toxic to microorganisms. Due to this, silver nanoparticles have found good applications in biomedical, antimicrobial, catalysis, human health and environmental remediation etc. Silver nanoparticles are extensively used for biomedical applications due to the antimicrobials, bio-detection and labelling, bio-magnetic separations, drug delivery, imaging, bone cement, therapeutics etc. Silver nanoparticles as a result of their excellent optical and electronic properties are promising catalytic materials for various applications. Some applications are in automotive catalyst, membranes, fuel cells, photocatalysts, propellants, scratch-resistant coatings, structural ceramics and solar cells, organic dyes degradation and chemo-catalytic reduction of ۴-nitrophenol (۴-NP) to ۴-aminophenol (۴-AP). This new technology also raises a serious concern about toxicological aspects of nanoparticles in food, with emphasis on the risk assessment and safety issue. In this paper the application of nanosilver, the antimicrobial performance of nanoparticles and their role in coatings, types of nanosilver are investigated.
