Abstract:
1. A modular microfluidic system comprising: a base substrate; a plurality of microfluidic assembly blocks, each individual microfluidic assembly block defining a channel and having a sidewall defining an aperture into the channel, wherein said plurality of microfluidic assembly blocks comprise an interlocking mechanism for operatively connecting each of said plurality of microfluidic assembly blocks to each other, wherein said interlocking mechanism comprises a tab extending from said sidewall of one microfluidic assembly block and a recess defined by said sidewall of another microfluidic assembly block, wherein said channel is further defined by said tab, and wherein said tab has a convex surface having a radius and defines the aperture into the channel of the microfluidic assembly block, and the recess defines a concave surface having a radius and with the aperture into the channel of the other microfluidic block defined thereon; and an adhesive component for bonding said plurality of microfluidic assembly blocks to one another and to said base substrate; wherein when said plurality of microfluidic assembly blocks is arranged on said base substrate, the aperture into the channel of one microfluidic assembly block aligns with the aperture of another microfluidic assembly block with the channels thereof connected along a plane parallel to said base substrate thereby forming a channel network defined by said plurality of microfluidic assembly blocks.
