Self-assembled host monolayer based chemical microsensors for volatile organic compounds
Abstract
The interaction of organic vapors with self-assembled host monolayers on the surface of 200 MHz surface acoustic wave (SAW) resonators is studied as a method of tracking toxins in the gas phase. Molecular self-assembly techniques were employed to achieve covalent surface-attachment of two families of {open_quotes}bucket{close_quotes} molecules - cyclodextrins and calix[n]arenes - to native oxides on Si<100> and single-crystal ST-cut quartz. The formation of the covalently-bound functionalized bucket monolayers on oxide surfaces was characterized by polarized, variable-angle, internal attenuated total reflection infrared spectroscopy and surface acoustic mass transduction. SAW based sensors were capable of detecting volatile organic compounds (VOCs) down to ppb levels. Pattern recognition with an array of complementary microsensors appears to be a viable approach for identifying and quantifying a particular VOC.
