    摘要: Bubble-free electrodes, electrochemical cells including bubble-free electrodes, analytical devices, and methods for preparing and using them are provided. The analytical devices each include at least one bubble-free electrode. Analytical devices that include an electrochemical cell and a sample containment device are also provided, wherein the electrochemical cell includes an anodic reservoir, a cathodic reservoir, an electrical connection between the anodic reservoir and the cathodic reservoir, and a first bubble-free electrode disposed within one of the anodic reservoir and the cathodic reservoir. A second electrode is disposed within the other reservoir and a power source is provided having a positive terminal that is normally in electrical contact with the first electrode, and a negative terminal that is normally in electrical contact with the second electrode. The analytical device further includes a power source polarity-inverting device for switching the contacts between the terminals of the power source and the first and second electrodes. The sample containment device includes a sample containment chamber having an opening for introducing a sample into the chamber and being positioned with respect to the electrochemical cell such that an electrical field generated by the electrochemical cell can influence a property of a component of a sample disposed in the sample containment chamber. Pressure-generating cells are also provided.

    摘要: The present invention provides methods and apparatus for mixing two or more liquids and detecting light emitted by the mixture. The method comprises forming a liquid droplet containing two or more liquids on a substantially planar surface in containerless containment on the surface and causing the droplet to deform in an essentially zero air flow environment thereby mixing the liquids and surrounding the planar surface with a reflective housing and photodetector. An apparatus of the invention comprises (a) a substantially planar support, (b) means for dispensing liquids onto the support to form a droplet, and (c) non-evaporative means for causing the droplet to deform without deforming the support thereby mixing the liquids and a two part reflective housing and photodetector which is moveable. The drop can be deformed by, for example, application of acoustic energy or a variable electrostatic field. The methods and apparatus have particular application to the determination of an analyte.
