Title:
MICROFLUIDIC CONCENTRATION GRADIENT LOOP
Document Type and Number:
WIPO Patent Application WO2001089696
Kind Code:
A3
Abstract:
A device for generating a stable concentration gradient in a microfluidic channel. A solution of a given concentration of a soluble compound and a diluting solution are co-delivered into a microfluidic channel. By varying the flow rates of the two solutions, the concentration of the soluble compound can be varied as a function of the length of the channel.
