The surface acoustic wave (SAW) sensor detects frequency changes in waves that propagate through its crystalline structure. This makes it ideal for detecting the presence of chemicals or biomarkers present in a liquid or gas. For example, it can detect cancer proteins attached to a receptor on the sensor surface.

 Researchers develop new acoustic sensor for chemical and biological detection

A new microscopic acoustic device that has been dramatically improved by scientists at the U.S. Department of Energy’s Argonne National Laboratory has the potential to form a new test for ovarian cancer or the presence of a particular chemical.

 Researchers fight friction and wear with one-atom-thick graphene

Nanoscientist Anirudha Sumant and his colleagues at Argonne’s Center for Nanoscale Materials and Argonne’s Energy Systems division applied a one-atom-thick layer of graphene, a two-dimensional form of carbon, in between a steel ball and a steel disk. They found that just the single layer of graphene lasted for more than 6,500 “wear cycles,” a dramatic improvement over conventional lubricants like graphite or molybdenum disulfide.

 Thin diamond films provide new material for micro-machines

Researchers at the Center for Nanoscale Materials at the U.S. Department of Energy’s Argonne National Laboratory and a handful of other institutions around the world have directed their focus to exploring microelectromechanical systems made of a relatively new material known as ultrananocrystalline diamond, which is a smooth and wear-resistant diamond thin film.

 Flexible, transparent thin film transistors raise hopes for flexible screens

The electronics world has been dreaming for half a century of the day you can roll a TV up in a tube. But scientists got one step closer last month when researchers at Argonne reported the creation of the world’s thinnest flexible, see-through 2-D thin film transistors.
