  • Method for determining the influence of a test substance on the heart activity of a vertebrate
    Patent number: 7256006
    Abstract: In a method for determining the influence of a test substance on the heart activity of a vertebrate the following steps are performed: a) preparation of a culture of spontaneously active heart cells of the vertebrate, b) extracellular measurement of electrophysiological data of the heart cells from step a), c) addition of the test substance to the culture from step a), d) repetition of the measurement from step b), and e) comparison of data from step b) and step d).
    Type: Grant

  • Method for making contact to cells present in a liquid environment above a substrate
    Patent number: 6989089
    Abstract: A microelement device has a plurality of microelements, which may be configured as microelectrodes, arranged on a substrate and adapted for making contact to cells present in a liquid environment. The cells are guided onto the microelectrodes, are isolated or are mechanically attracted to the microelectrodes. A negative-pressure force or a hydrodynamic force may be applied on the cells. Also described are a method for making contact to the cells, and a method for manufacturing the microelement device is disclosed.
