The EUROoCS Conference 2021 is a scientific meeting covering all aspects of OoC research, development and application. Topics such as micro- and nanotechnology, microfluidics, tissue engineering, organoids, (multi-)organ models, standardization, upscaling, qualification, regulatory aspects and disease modeling will be covered. This year, two special sessions, ‘Meet your Regulatory Advisory Board (RAB)’ and ‘Meet your Industrial Advisory Board (IAB)’, will demystify the world of regulators and highlight industry bottlenecks. The members of the RAB and IAB cordially invite you to overcome potential barriers, exchange ideas with them and benefit from their expertise in these panel discussions.
