Title:
MICRO/NANO FLUIDIC 3-DIMENSIONAL ELECTRODE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2004/105153
Kind Code:
A2
Abstract:
The present invention discloses a three-dimensional electrode system having an integrated micro/nano fluidic channel. The three-dimensional electrode system comprises a first dielectric substrate, a second dielectric substrate facing the first dielectric substrate with a predetermined gap in-between, a plurality of oxidation electrodes formed on the first dielectric substrate, and a plurality of reduction electrodes formed on the second dielectric substrate. A micro/nano fluidic channel is formed between the first and second dielectric substrates. The oxidation and reduction electrodes are formed in predetermined intervals along the micro/nano fluidic channel and substantially perpendicular to the micro/nano fluidic channel. The electrodes are electrically interconnected. A bio-fluidic flows through the micro/nano fluid channel in zigzags, not straight, such that mixing of the fluid can be facilitated, and oxidation and reduction reactions of electroactive species contained in the fluid can be electrochemically analyzed with a high degree of efficiency.
