TLDR
The chemical and toxicological principles that underlie the antimicrobial activity of metals are described and the preferences of metal atoms for specific microbial targets are discussed.Abstract:
Metals have been used as antimicrobial agents since antiquity, but throughout most of history their modes of action have remained unclear. Recent studies indicate that different metals cause discrete and distinct types of injuries to microbial cells as a result of oxidative stress, protein dysfunction or membrane damage. Here, we describe the chemical and toxicological principles that underlie the antimicrobial activity of metals and discuss the preferences of metal atoms for specific microbial targets. Interdisciplinary research is advancing not only our understanding of metal toxicity but also the design of metal-based compounds for use as antimicrobial agents and alternatives to antibiotics.read more

Hard and soft acids and bases
TL;DR: In this paper, the rate data for the generalized nucleophilic displacement reaction were reviewed, and the authors presented a method to estimate the rate of the generalized displacement reaction in terms of the number of nucleophiles.

Absolute hardness: companion parameter to absolute electronegativity
Robert G. Parr,Ralph G. Pearson +1 more
TL;DR: In this paper, a property called absolute hardness eta is defined for neutral and charged species, atomic and molecular, for both hard and soft acids and bases, by making use of the hypothesis that extra stability attends bonding of A to B when the ionization potentials of A and B in the molecule are the same.

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.
