Antimicrobial nanostructures in food packaging
TLDR
In this paper, the authors summarize published data regarding mechanisms and scopes of action of nanostructured antimicrobial agents, as well as their proposed applications for food packaging purposes.Abstract:
Active antimicrobial food packaging systems are supposed not only to passively protect food products against environmental factors, but also to inhibit or retard microbial growth on food surfaces, extending food shelf life. Nanostructured antimicrobials have a higher surface area-to-volume ratio when compared with their higher scale counterparts. Therefore, antimicrobial nanocomposite packaging systems are supposed to be particularly efficient in their activities against microbial cells. The objective of this review is to summarize published data regarding mechanisms and scopes of action of nanostructured antimicrobial agents, as well as their proposed applications for food packaging purposes.read more

Comparative Numerical Study of Titanium and Silver Nano-particles Migration from Nano-composite of Polystyrene into Simulants on Experimental Data Basis
TL;DR: In this paper, it was found that nanoparticle migration rate in acidic food was higher than fatty food and that in the migration process the diffusion coefficient was more important than the amount of nanoparticles concentration.

A mechanistic study of the antibacterial effect of silver ions on Escherichia coli and Staphylococcus aureus.
TL;DR: The existence of elements of silver and sulfur in the electron-dense granules and cytoplasm detected by X-ray microanalysis suggested the antibacterial mechanism of silver: DNA lost its replication ability and the protein became inactivated after Ag(+) treatment.

Negligible Particle-Specific Antibacterial Activity of Silver Nanoparticles
TL;DR: This work suggests that AgNP morphological properties known to affect antimicrobial activity are indirect effectors that primarily influence Ag(+) release, and antibacterial activity could be controlled by modulating Ag(+ release, possibly through manipulation of oxygen availability, particle size, shape, and/or type of coating.

Preparation and antibacterial activity of chitosan nanoparticles.
TL;DR: Results show that chitosan nanoparticles and copper-loaded nanoparticles could inhibit the growth of various bacteria tested and exposed to S. choleraesuis led to the disruption of cell membranes and the leakage of cytoplasm.
