3Brain developed and distributes the world’s first commercial CMOS-based high-resolution Microelectrode Array (MEA), a Biosensor integrating thousands of tiny electrical sensors in a small area. Our Biosensor allows non-invasive (in vitro) investigations of electrogenic cells, such as neurons, cardiac and muscle cells. The technology can be used to investigate electroactive cells' fundamental properties (e.g., neural code for learning and memory), to study and find new treatments to different types of diseases (e.g. Alzheimer and epilepsy) and to assess compounds/chemical toxicity.
