摘要： The present invention is generally directed to a microfabricated gas chromatograph column having two patterned substrates, each optionally having a stationary phase material coating, bonded together to provide a continuous flow channel. The flow channel can have a serpentine arrangement or a modified serpentine arrangement comprising alternating series of consecutive turns in one direction where each series has enough turns to move carrier gas and analyte molecules from the center of the column cross section to an outer wall of the channel or from one outer wall of the channel to the opposite outer wall. Different portions of the substrates can be coated with differing thicknesses of stationary phase material and/or with different stationary phase materials. The column can have a circular cross-section or a semi-circular cross-section where the flat portion of the cross-section has grooves. Also disclosed is the related method of making the microfabricated gas chromatograph column.

摘要： Micro-opto-mechanical chemical sensors and methods for simultaneously detecting and discriminating between a variety of vapor-phase analytes. One embodiment of the sensor is a photonic microharp chemical sensor with an array of closely spaced microbridges, each differing slightly in length and coated with a different sorbent polymer. The microbridges can be excited photothermally, and the microbridges can be optically interrogated using microcavity interferometry. Other actuation methods include piezoelectric, piezoresistive, electrothermal, and magnetic. Other read-out techniques include using a lever arm and other interferometric techniques.
