Abstract
A biological molecule detection device that includes a detection array, arranged on a body and having one or more probes for detecting corresponding electrically charged molecules, wherein a time varying electric field generating circuit is provided for generating at least one time varying electric field around the detection array within the detection region. The time varying electric field moves the electrical charged molecules repeatedly back and forth over the probes, thus providing increased opportunities for interaction and speeding the detection process.

1-20. (canceled)
A microfluidic detection device, comprising a body having a detection region, said detection region comprising a plurality of probes to detect a plurality of electrically charged molecules, and a time varying non-uniform electric field generating circuit generating a plurality of time varying voltage waves in sequential variable, non-parallel directions to dynamically move the plurality of electrically charged molecules within said detection region, so that the electrically charged molecules are prevented from reaching a substantially steady configuration within said detection region.
A microfluidic device, comprising a semiconductor body having a detection chamber,
- said detection chamber having a probe to detect electrically charged molecules, and
- a time varying electric field generating circuit having a plurality of electrodes, separate from and surrounding said probe, and a driving circuit coupled to said plurality of electrodes, to provide respective bias voltages to said electrodes generating a plurality of time varying non-uniform voltage waves in sequential variable, non-parallel directions to dynamically move said electrically charged molecules within said detection region, so that the electrically charged molecules are prevented from reaching a substantially steady configuration within said detection region.
