A microscreen, substantially formed of a photoresist material, is produced by applying a photoresist layer to a support using a liquid photoresist, partially covering the photoresist layer with a mask that defines the structure of the microscreen, exposing the photoresist to radiation, developing the photoresist, and removing the photoresist from the support.

Method for producing a microscreen

A method produces a microscreen by providing a support and applying a photoresist layer with a definable thickness to the support. The photoresist is exposed by radiation using a mask that defines the structure of the microscreen. The photoresist is then developed. The thickness of the photoresist layer is selected such that, in a sub-region of the photoresist layer, the radiation used for the exposure penetrates only so slightly that practically no cross-linking of the photoresist takes place.

An arrangement and a method measures cell vitalities with a sensor array. The sensor array is formed on a surface of a semiconductor chip. The semiconductor chip has integrated circuits and an integrated circuit is associated with each sensor of the sensor array, for processing the measurement signals of the respective sensor. The integrated circuits are formed in the semiconductor chip spatially in each case below the associated sensor and neighboring sensors of the sensor array have a center-to-center in the range of micrometers. The pH and/or pOcan be measured in the environment of a living cell.
