Animal testing could slowly be replaced with experiments using artificial tissue thanks to groundbreaking work using lasers done by the Vienna Technical University (TU Wien) in Austria.

The idea behind the research was the creation of artificial organs in a procedure known as delivering an "organ on a chip" or "human on a chip."

During the procedure, tissue parts are created which then interact with each other. They are placed on a chip of a few centimeters in size and can be supplied with very specific nutrients or also with pharmaceutical compounds in a highly precise manner.

In this way, important information can be gathered about the effect of drugs without having to resort to animal testing.
