Which potentials does the field of optogenetics offer? What are the future business fields and sales markets? The Innovation Network Optogenetics, which started in June, is out to answer these questions. A two-day session on November 28th and 29th, 2017, in Hannover, will bring together stakeholders from different technology areas, in order to bundle competencies and to create synergy. The network was initiated by the Laser Zentrum Hannover e.V. (LZH).
