West Chester University Master’s Theses

Anthropogenically-produced nanoparticles are a form of nanotechnology being used in industries including food and textiles. Humans and livestock are frequently exposed to metal-containing nanoparticles (MCNPs), that have been washed into streams and rivers, have been deliberately used in food packaging as antimicrobials, preservatives or for supplementation. The animal microbiome, which consists of a diverse community of microorganisms, provides a number of benefits to the host in terms of nutrition availability, immune support, and can influence behavior. Biofilms of diverse microbes may cause detrimental effects, for instance by causing dental diseases in humans. However, the scientific community has not reached consensus …
