POTENTIAL ENERGY SURFACE SENSOR CHIP AND USE OF POTENTIAL ENERGY SURFACES ON A SENSOR CHIP AND METHOD FOR PREVENTING A SENSOR CHIP FROM BEING SOILED

摘要

A method to avoid contaminations on a sensor chip (1), which has a sensor area (17) and in a flowing medium is arranged, in which at least one potential surface (44, 47, 50, 53) on the sensor chip (1) by means of an applied electric voltage generates an electrical field, the entrained particles of the medium around the sensor area (17) deflects.
