BIODECON - Project develops plasma sterilization

Safe and gentle

Surgical instruments

One single case of Creutzfeldt-Jakob disease in a Canadian hospital resulted in the destruction of all 20,000 medical instruments as a precaution. Up to now, no method has been available for reliable decontamination of the affected instruments in this case. But now there is change in sight: today, plasma sterilization already gives biomolecules and bacteria no chance, whilst protecting even delicate instruments.

Chemists write and read in the nanometre range

The molecular magic drawing board

drawing board

“You remember those magic drawing boards for children, don’t you? Where you write on them and then wipe them clean with a slider so you can start again?” Prof. Dr. Martina Havenith-Newen (Physical Chemistry II) starts gesticulating. “Yes, and that's how it works here too, only in the nanometre range!” adds her colleague Prof. Dr. Wolfgang Schuhmann (Analytical Chemistry). They banter back and forth: “We start off by writing electrochemically” (Schuhmann) “… and then we read what’s written with infrared spectroscopy” (Havenith-Newen),” … yes and then we can erase it all – and start writing again from the beginning!” (Schuhmann). He leans back happily in his chair. “That's the 'molecular magic drawing board'!”

They work best under stress: microalgae as hydrogen factories

Home-grown hydrogen

algae cultures

In the search for alternative, environment-friendly sources of energy, microalgae are highly promising. They can produce hydrogen, which generates electricity in the fuel cell. In the EU project “Solar H”, researchers are trying to optimize the algae system. The goal is an algae fermenter for home use.
