Abstract
A method is provided for fabricating a multi-layer microfluidic device on a base. A first layer is positioned on the base in a spaced relationship thereto so as to define a construction cavity therebetween. The first layer has a passageway therethrough which communicates with the construction cavity. A mask is positioned between the construction cavity and an ultraviolet source. The mask corresponds to a channel to be formed in the construction cavity. The construction cavity is filled with material and a portion of the material is polymerized within the construction cavity so as to solidify the same. The solidified material defines the channel. Thereafter, the material is flushed from the channel in the construction cavity.
