Abstract

A combination of components in a capillary flow channel use capillary forces to passively control the movement of liquid samples within a microfluidic device. To detect a target, a liquid sample introduced to a proximal portion of a capillary channel of a microfluidic device moves by capillary action along the specific components of capillary channel.
