Plasma seen as weapon against infection

Technology drawing on long-running research conducted in space could lead to a new way to keep hospital patients safe from infections, European researchers say.

Using plasma -- superheated, electrically charged gas -- Gregor Morfill at the Max Planck Institute for Extraterrestrial Physics say he is developing ways to kill bacteria and viruses that can cause infections in hospitals.

The research began on the International Space Station, where his physics experiments, funded by the European Space Agency, have been running since 2001, an ESA release from Paris said Friday.

The work in space has led to the potential for very practical terrestrial applications, Morfill said.

Plasma dispensers can tackle a serious problem -- super-strains of bacteria that can survive the strongest antibiotics in medicine's arsenal -- that has been growing in recent years, he said.

"What we have with plasma is the possibility to supplement our own immune system," Morfill said.

Morfill is designing a system that makes use of plasma's innate anti-bacterial properties to make disinfection easy and quick.
