ABSTRACT
In the context of a neurobionic approach to chemical analysis and sensorics, this article depicts the development of a miniaturized autonomous perfusion chamber setup for the growth and the electrical as well as optical investigation of (neural) cell cultures in vitro. We suggest an autonomous, modular, temperature-controlled, transparent, and sealed perfusion cell culture housing adaptable to various mounts, sizes and different needs. The design includes the electronics of a temperature and medium supply control unit. The setup combines the possibility of uninterrupted cell culturing with simultaneous microscopic and analytical investigation of variable amounts of cells or organs of human, animal, or plant origin under sterile conditions on different substrates without the need of an external incubator or a sterile working environment. Its use is demonstrated exemplarily with neuronal cultures from embryonic chicken that were cultured in a prototype system for 3 weeks. It turned out that cell survival in such a chamber was prolonged with timed medium flow rather than continuous perfusion.
