The JILA "bathtubs" consist of about 35 picoliters (trillionths of a litre) of water on a glass slide. Gently focused infrared laser light is used to heat a nanoscale column of water. "Exact sizes of the laser beam and sample area don't matter. What's important is having time and temperature control over volumes of fluid small enough to be able to look at single molecules," says NIST/JILA Fellow David Nesbitt, senior author of the paper.
