Vitamin C in humans must be ingested for survival. Vitamin C is an electron donor, and this
property accounts for all its known functions. As an electron donor, vitamin C is a potent …

Vitamin C readily scavenges reactive oxygen and nitrogen species and may thereby prevent
oxidative damage to important biological macromolecules such as DNA, lipids, and proteins …

Copper-based nanoparticles are an important class of materials with applications as
catalysts, conductive inks, and antimicrobial agents. Environmental and safety issues are …

When environmental conditions deteriorate and become inhospitable, generic survival
strategies for populations of bacteria may be to enter a dormant state that slows down …

The metal ions carcinogenic to humans are As, Be, Cd, Cr and Ni, and the candidates also
