The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB is coordinating the establishment of a European research network to promote organ-on-a-chip technology. Organ-on-a-chip systems enable the recapitulation of human organ tissues on a very small scale. They are regarded as a future alternative to animal models and as a technology with great potential for pharmaceutical research and personalized medicine. Since the development of organ-on-a-chip systems requires skills and expertise from various disciplines, the primary aim of the EUROoC network is the interdisciplinary training of young scientists.
