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