The Perks of Biosensors

The field of biosensors may be getting a boost from an unlikely source: coffee rings. UCLA researchers are studying the "coffee ring" phenomenon - the observation that many liquids, when spilled, evaporate to leave a darker ring around the perimeter that contains a much higher concentration of particles than the center. A...
