Copper: introduction to the chemical element
What is copper? Copper is a relatively soft, reddish metal that conducts heat and electricity well. It's roughly the 25th most abundant chemical element in Earth's crust and is found throughout the world, from the Andes mountains of Chile (the leading producer, which generates just under a third of the world's copper) to the craggy Cornish coastline …

Only small amounts of copper are typically stored in the body, and the average adult has a total body content of 50–120 mg copper [1,2]. Most copper is excreted in bile, and a small amount is excreted in urine. Total fecal losses of copper of biliary origin and nonabsorbed dietary copper are about 1 mg/day [1,2].

Chemistry of Copper
Copper (I) chemistry is limited by a reaction which occurs involving simple copper (I) ions in solution. This is a good example of disproportionation - a reaction in which something oxidises and reduces itself. Copper (I) ions in solution disproportionate to give copper (II) ions and a precipitate of copper. The reaction is:

Killing infectious bacteria: Is copper the way to go?
The ions then slip inside the microbe and dismantle its DNA, ultimately killing it. The copper appears to kill viruses such as norovirus as well as C. difficile and other harmful bacteria, says Schmidt. Out of the 215 copper beds that were sampled for bacteria, 94% of them had less than 250 bacterial colonies — the disinfection risk threshold.
