Effect of Copper Ion Concentration on Bacteria and Cells

To determine relevant copper ion concentrations, ion release rates from copper and a 10 wt. % Cu Ti-alloy were investigated. Survival studies were performed on MC3T3 cells and Staphylococcus epidermidis bacteria, after exposure to Cu ions concentrations ranging from 9 × 10-3 to 9 × 10-12 g/mL.

Copper in Cell Culture

Copper is an essential element in cell culture. However, classical media do not typically contain it in their basal formulations. This is likely because sera used at 5 to 10% provides sufficient copper for cell growth and survival, approx. 50 to 100 ng/mL. Efforts to develop serum-free media necessitate the addition of copper to the cell ...

A variety of indicators were used to establish the RDA for copper, including plasma copper concentration, serum ceruloplasmin activity, superoxide dismutase activity in red blood cells, and platelet copper concentration . The RDA for copper reflects the results of depletion-repletion studies and is based on the prevention of deficiency (Table 1).

Galvanic corrosion

Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte.A similar galvanic reaction is exploited in primary cells to generate a useful electrical voltage to power portable devices.

Conditions Contributing to Underground Copper Corrosion

Oxygen-type concentration-cell corrosion is often the explanation for the preferential underside corrosion of a copper water tube. The underside of the tube is often in contact with reduced oxygen-content, undisturbed soil, whereas the upper portion of the tube is exposed to aerated backfill.
