    Abstract: A microactuator preferably in the form of a microminiature valve for controlling the flow of a fluid carried by a flow channel includes a first substrate having a thermally-actuated member selectively operated by a thermal actuator such that the first substrate thereby develops thermal energy, and a second substrate having opposed first and second major surfaces. The second substrate is attached to the first substrate at the first major surface. The second major surface defines an isolation cell for enclosing a volume when the second substrate is attached to the support to thereby reduce the thermal mass of the microactuator and to thermally isolate the first substrate from the support.

    Abstract: A method and system for forming tungsten structures in a semiconductor device which uses a chromium protective layer to protect underlying semiconductor layers during the etching process and a chromium mask layer so that tungsten structures can be formed with high aspect ratios using a reactive ion etching to etch the tungsten with a carbon tetrafluoride oxygen plasma in a reactive ion etcher. Long overetches can be achieved because of the high selectivity of chromium to the carbon tetrafluoride/oxygen plasma. The anisotropic nature of the reactive ion etcher prevents undercut during long overetches of the tungsten to further decrease losses in linewidth or increases in resistance as a result of overetching.

    Abstract: A method of detecting analytes in a microfluidic sample includes introducing at least one type of analyte, at least one type of carrier particle, and a fluid into a mixing chamber of a system. The at least one type of analyte binds to a site on the at least one type of carrier particle to form a microfluidic suspension including at least one analyte-bound particle suspended in the fluid. The at least one analyte-bound particle is separated from the fluid by exposing the suspension to physical forces, magnetic forces, or combinations thereof. A spectrophotometric property of a solution is altered using the at least one analyte-bound particle. The altered spectrophotometric property is measured with an optical detection system.

    Abstract: A pump apparatus comprising an enclosure for holding a volume of fluid; an intake one-way valve for enabling intake of fluid into the enclosure; a discharge one-way valve for enabling discharge of fluid from the enclosure; a diaphragm for cyclically deflectably increasing and decreasing the volume of the enclosure whereby fluid is oscillatingly drawn into the enclosure and discharged therefrom; a heating assembly for selectively oscillatingly applying heat to the diaphragm and terminating application of heat thereto for selectively oscillatingly deflecting the diaphragm.
