The invention relates to a device for electrically reading microarrays, that can be cleaned and used more than once. The device (1, 1', 1 ") for reading microarrays (6) comprises the following elements: a base (2, 2', 2") comprising support means (3, 3', 3") for positioning the test surface (7) of the microarray (6) parallel to a reading surface (4) of the base (2, 2', 2"); a matrix of transducers (5, 5', 5") arranged on the reading surface (4) of the base (2, 2', 2"), translating a variation of an electrical or chemical value into a variation of an electrical value; and reading means (10) which are connected to the transducers (5, 5', 5") and interpret the electrical signals from the transducers (5, 5', 5"). |
