Science and Technology, Magenta Microheater

Magenta Microheater. A NIST-developed microheater device can be used to quickly detect toxic gases such as sarin or mustard gas.

Slight variations in the thickness of the sensing film covering the microheater cause changes in color that have been enhanced in this micrograph. NIST researchers will use the AML's Nanofabrication Facility to make arrays of such microsensors tailored to sense specific chemicals at part per billion concentration levels.
