With a photocopier and transparency film anyone can create a polymer lab on a chip

A student in the new Microfluidics Lab peels back the polymer, showing engraved channels, from an ink-transparency template

A local high school physics teacher Joe Childs had a better idea for creating microfluidics lab on a chip.

1. Design the layout of the channels in PowerPoint
2. Print the image, and photocopy it onto a classroom-style transparency film several times until the layers of ink create raised ridges.
3. The process results in a negative mold that can then be used to create channels in the polymer chip

With little more than a conventional photocopier and transparency film, anyone can build a functional microfluidic chip.
