A new painless and minimally invasive microneedle technology can extract large volumes of pure interstitial fluid for further study. Developed at Sandia Labs and the University of New Mexico, the microneedles are a few hairs-breadths wide and can sip the clear fluid between cells in the middle layer of skin. This is below the topmost layer of dead skin cells and above the layer of skin where veins and nerves reside. The clear, colorless fluid is called interstitial fluid and is similar to blood plasma.
