Fabrication and Antibacterial Properties of Silver/Graphite Oxide/Chitosan and Silver/Reduced Graphene Oxide/Chitosan Nanocomposites
Mina Keshvardoostchokami,Mina Keshvardoostchokami,Farideh Piri,Vahab Jafarian,Abbasali Zamani +4 more
TL;DR: In this paper, the results confirmed that the prepared nanocomposites exhibited broad-spectrum antibacterial activity against the two bacteria, including Gram-positive bacterium Corynebacterium glutamicum and Gram-negative bacterium Escherichia coli strain DH5α, over durations of 8 and 20 hours.
Journal ArticleDOI
Silver ions cause oscillation of bacterial length of Escherichia coli
TL;DR: A model similar to the predator-prey argument was developed to understand the observed oscillations of cell-length upon exposure to Ag+ ions and successfully produced the oscillations, which explained the observed heterogeneity in the bacterial responses to Ag- ions.

The bactericidal effect of silver nanoparticles
Jose Ruben Morones,Jose Luis Elechiguerra,A. Camacho,Katherine B. Holt,Juan B. Kouri,Jose Tapia Ramirez,Miguel Jose Yacaman +6 more
TL;DR: The results indicate that the bactericidal properties of the nanoparticles are size dependent, since the only nanoparticles that present a direct interaction with the bacteria preferentially have a diameter of approximately 1-10 nm.
