Abstract
The invention relates to a bioreactor () which is designed for cultivating biological cells (), comprising a container () configured to receive a cultivation medium (), and a plurality of substrate filaments () which are arranged in the container () and are configured for a temporary adherent coupling of the biological cells () to the substrate filaments (). The substrate filaments () are provided with a surface layer () which is switchable between an adherence state, in which the biological cells () can be coupled adherently to the surface layer (), and a release state, in which the adherent coupling of the biological cells () to the surface layer () is reduced in comparison to the binding state. The invention also relates to a method for processing biological cells () in the bioreactor ().
