CNM Technologies GmbH is a spin-off of the University of Bielefeld. The company has developed the technology to produce extremely thin (one millionth of a millimeter), polymer-like carbon films (carbon nanomembranes). Carbon nanomembranes have multiple material characteristics which can be specifically adapted for a great variety of applications. This novel material class forms a platform technology that can be used in many sectors, such as microelectronics, sensor technology, medical engineering and energy engineering. Object slides for transmission electron microscopes were the first product to be developed and successfully launched on the market.
