CCrawford sez, "Michelle Khine couldn't afford the $100,000 fabrication gear to make micro-fluidic chips needed for chip-based diagnostic tests. She turned to Shrinky-Dinks and found a new way to solve the problem."
To test her idea, she whipped up a channel design in AutoCAD, printed it out on Shrinky Dink material using a laser printer, and stuck the result in a toaster oven. As the plastic shrank, the ink particles on its surface clumped together, forming tiny ridges. That was exactly the effect Khine wanted. When she poured a flexible polymer known as PDMS onto the surface of the cooled Shrinky Dink, the ink ridges created tiny channels in the surface of the polymer as it hardened. She pulled the PDMS away from the Shrinky Dink mold, and voilà: a finished microfluidic device that cost less than a fast-food meal.
Khine began using the chips in her experiments, but she didn't view her toaster-oven hack as a breakthrough right away. "I thought it would be something to hold me over until we got the proper equipment in place," she says. But when she published a short paper about her technique, she was floored by the response she got from scientists all over the world. "I had no idea people were going to be so interested," Khine says.
In the late 1960s and 1970s, the mind-expanding modus operandi of the counterculture spread into the realm of science, and shit got wonderfully weird. Neurophysiologist John Lilly tried to talk with dolphins. Physicist Peter Phillips launched a parapsychology lab at Washington University. Princeton physicist Gerard O’Neill became an evangelist for space colonies. Groovy Science: Knowledge, […]
In a lead editorial in the current Nature, John Wilbanks (formerly head of Science Commons, now “Chief Commons Officer” for Sage Bionetworks) and Eric Topol (professor of genomics at the Scripps Institute) decry the mass privatization of health data by tech startups, who’re using a combination of side-deals with health authorities/insurers and technological lockups to […]
The Wall Street Journal reports that storytellers—people with a natural inclination to craft concise yet compelling narratives without rambling—were found to be hot by science. Feels good to be a writa. The results were the same across all three studies: Women rated men who were good storytellers as more attractive and desirable as potential long-term […]
