A children’s toy inspires a cheap, easy production method for high-tech diagnostic chips Purposeful play: Biomedical engineer Michelle Khine sits in her lab at the University of California, Irvine, where she uses Shrinky Dinks straight from the toy store to build microfluidic devices. Credit: Dave Lauridsen Multimedia How Khine Builds Microfluidic Devices Watch Khine explain and demo her devices. In 2006, Michelle Khine arrived at the University of California's brand-new Merced campus eager to establish her first lab. She was experimenting with tiny liquid-filled channels in hopes of devising chip-based diagnostic tests, a discipline called microfluidics. The...
