Abstract
The embodiments of the present disclosure relate to a micro-fluidic device comprising a substrate, a cavity in the substrate and a plurality of micro-pillar columns located inside the cavity. The micro-pillars columns are configured to create a capillary action when a fluid sample is provided in the cavity. A micro-fluidic channel is present between two 5 walls of any two adjacent micro-pillars in a same micro-pillar column. Each of the two walls comprises a sharp corner along the direction of a propagation path of the fluid sample in the micro-fluidic channel thereby forming a capillary stop valve. A notch provided in a sidewall of the cavity acts as a capillary stop valve.
