Sensor biochips could aid in cancer diagnosis and treatment
Date:10/21/2009

tem could be used in the treatment of inoperable tumors, for example pancreatic tumors.

In the past, microchips have also been developed at the TUM's Heinz Nixdorf Chair for use in other research fields. For example, one such system is used in the analysis of the water quality of streams and rivers. In this case, a small pump removes samples at regular intervals from the water body and channels it via a pipe to a sensor chip on which algae have been planted. As algae are highly sensitive to toxic substances, they are particularly suitable for water analysis and react to the minutest impurities: their metabolic activity, which is measured on the basis of their oxygen production, declines in less than one minute in the presence of toxins. The data recorded by this sensor system are transmitted via mobile telephone to a computer that raises the alarm. The TUM research team won the E.ON Environmental Award, presented by the Bavarian energy company of the same name, for this system in 2008.
