Meßanordnung zum Nachweis einer ein- oder mehrdimensionalen Verteilung einer chemischen oder biochemischen Komponente

摘要

The invention relates to a measuring device for one-dimensional or multidimensional detection of chemical or biological components (analytes). A photosensitive contact is applied to a semiconductor structure and the modification of the potential barrier of the contact upon illumination is used as a functional principle, thereby avoiding all stated disadvantages of prior art, while at the same time guaranteeing two-dimensional local resolution of the analyte substance to be detected by means of a sensor.
