Very innovative use of Shrinky dinks

“She has begun to make chips directly out of the Shrinky Dinks by etching the design into the plastic using syringe tips. As the plastic shrinks, the channels become narrower and deeper--perfect for microfluidics. She can even make three-dimensional chips by melting several etched Shrinky Dinks together. The whole process, from design to finished chip, takes only minutes.”
