Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way. Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more difficult task. Important transport processes in biology, for example the transport of oxygen, sugar and other substances into the tissue, have not yet been fully understood. This is now going to change with a completely new approach to the problem: At the Vienna University of Technology, tissue is being grown on the biochip - so-called "organs-on-a-chip". This allows you to precisely control and measure complicated biological processes - much better than would be possible in animal testing or by experimenting on humans.
