  • Method for processing a sensor chip
    Patent number: 9086346
    Abstract: The method for processing a sensor chip in accordance with the present invention has: 1) providing an acoustic wave operation system and a biochemical sensor chip, wherein the acoustic wave operation system has a piezoelectric transducer generating at least one cycle of longitudinal acoustic waves by a driving voltage and wherein a probe is immobilized on a surface of the biochemical sensor chip; 2) arranging the piezoelectric transducer at a distance from the biochemical sensor chip and filling therebetween with a medium for transmitting longitudinal acoustic waves; and 3) applying longitudinal acoustic waves to the biochemical sensor chip to remove an adsorbate bound to the probe.
