    Abstract: Micro-fluid devices and methods for their use are provided. The subject devices are characterized by the presence of at least one micro-valve comprising a phase reversible material, e.g. a reversible gel, that reversibly changes its physical state in response to an applied stimulus, e.g. a thermoreversible gel. In using the subject device, fluid flow along a flow path of the device is modulated by applying an appropriate stimulus, e.g. changing the temperature, to the microvalve. The subject devices find use in a variety of applications, including micro-analytical applications.

    Abstract: Methods and compositions for modifying the surface of a polymeric substrate are provided. In the subject methods, at least a portion of the surface of the polymeric substrate is contacted with a biofouling resistant surfactant composition. At least a portion of the surfactant molecules of the composition are end modified with a non-reactive, charged end group that is charge stable over a pH range of about 2 to 12. The subject methods and compositions find particular use with electrophoretic devices, such as capillary electrophoretic devices.

    Abstract: A miniaturized total analysis system (" mu -TAS") (200) comprising a miniaturized planar column device (2) is described for use in liquid phase analysis. The mu -TAS (200) comprises microstructures fabricated by laser ablation in a variety of novel support substrates (4). The mu -TAS (200) includes associated laser-ablated features (10) required for integrated sample analysis, such as analyte detection means and fluid communication means. mu -TAS (200) constructed according to the invention is useful in any analysis system for detecting and analyzing small and/or macromolecular solutes in the liquid phase and may employ chromatographic separation means, electrophoretic separation means, electrochromatographic separation means, or combinations thereof.
