Abstract

A microfluidic device with interconnects. The device includes a first layer; a second layer, the first layer and the second layer assembled such as to face each other; a microchannel in said second layer; a tapered conduit having a tapered portion, wherein the tapered portion is inserted in a correspondingly shaped via formed in the first layer at the level of an end of the microchannel such that fluid communication is enabled between the microchannel and the conduit, and blocked in the via by way of the assembled first layer and second layer.

First claim

What is claimed is:

1. A microfluidic device comprising:
a first layer;
a second layer, wherein said first layer and said second layer are assembled to face each other;
a microchannel in said second layer;
a tapered conduit having a tapered portion, wherein said tapered portion is inserted in a correspondingly shaped via formed in said first layer at the level of an end of said microchannel such that fluid communication is enabled between said microchannel and said conduit,…
