Coating of Gold Na**particles Keeps Bugs Off Medical Devices
http://www.medgadget.com/wp-content/uploads/2015/02/antibacterial-materials.jpg
At the*Institute of Physical Chemistry of the Polish Academy of Sciences researchers have developed a new highly effective antibacterial coating that should work well on*medical devices. The material is initially a liquid combination of a boron compound blended with colloids of gold. When a substance is introduced to polymerize the material, any solid objects within the bath become coated by a gold composite layer. This happens within just a few minutes and the material is stable, staying effective for a long time after it’s applied.
In laboratory tests, the researchers behind the new coating showed effectiveness against E. coli and Staph. aureus, as well as*other bacteria. They demonstrated that the amount of bacteria reduces by around 90% after 21 hours when in contact with the gold na**compound.
Conveniently, the material is **n-toxic to human cells, staying put on a device surface and **t actually being released into the body. They actually had human cell cultures grow on top of the antibacterial coating for months, developing **rmally and maybe even benefiting a bit from the new material.
