Mechanistic studies on DNA damage by minor groove binding copper–phenanthroline conjugates [PDF]

open access: yes, 2005
Copper–phenanthroline complexes oxidatively damage and cleave nucleic acids. Copper bis-phenanthroline and copper complexes of mono- and bis-phenanthroline conjugates are used as research tools for studying nucleic acid structure and binding interactions.

A long-term copper exposure on freshwater ecosystem using lotic mesocosms: Individual and population responses of three-spined sticklebacks (Gasterosteus aculeatus) [PDF]

open access: yes, 2007
Three-spined stickleback (Gasterosteus aculeatus) was used as the highest trophic level predator in an outdoor mesocosm study assessing the effect of environmentally realistic copper concentration (0, 5, 25 and 75 μg L−1) over 18 months of continuous ...

Magnetic resonance imaging (MRI) of heavy-metal transport and fate in an artificial biofilm [PDF]

open access: yes, 2008
Unlike planktonic systems, reaction rates in biofilms are often limited by mass transport, which controls the rate of supply of contaminants into the biofilm matrix.

A combined photolytic–electrolytic system for the simultaneous recovery of copper and degradation of phenol or 4-chlorophenol in mixed solutions [PDF]

open access: yes, 2008
The effects of the presence of copper on the photooxidation of phenol and 4-chlorophenol and of the presence of the phenols on the recovery of copper by electrodeposition are studied in three systems: a photolytic cell in the presence and absence of TiO2

Inactivation of murine norovirus on a range of copper alloy surfaces is accompanied by loss of capsid integrity

open access: yes, 2015
Norovirus is one of the most common causes of acute viral gastroenteritis. The virus is spread via the fecal-oral route, most commonly from infected food and water, but several outbreaks have originated from contamination of surfaces with infectious ...
