Folding a drop of water solves a longstanding challenge in portable diagnostic devices

If you’ve ever stopped to watch rain falling on a windowpane, you’ve seen what happens when two drops of water touch and merge into one. But you probably never imagined that the physics at work in this phenomenon was the key to unlocking a solution for the development of miniaturized personal biological analysis devices. An international team of scientists from IBM Research – Zurich and the Microfluidics for Oncology Laboratory at Polytechnique Montréal made this remarkable discovery, and recently published the results of their work in Nature. Installing a lab on a chip: a longstanding challenge For the past 20 years or so, research conducted around the world into so-called lab-on-a-chip devices has shown promise for the perfecting of portable tools that would require only a sample of bodily fluid (e.g., blood, saliva, urine) to screen for diseases or measure biological data. These kinds of miniature systems already exist for simple measurements made with few reagents: glucose meters
