摘要： A method for forming a tapered region in a first layer of a first material is disclosed. The method comprises forming an accelerator layer of a second material on the first layer and forming a mask layer disposed on the accelerator layer. The accelerator layer is exposed to a first etch that removes the second material in a first region and laterally etches the accelerator layer along a second region to expose the first layer in the second region to the first etch. Since the time for which the first layer is exposed to the first etch in the second region is based on the progress of the lateral etch of the accelerator layer, the first etch tapers the first layer in the second region.

摘要： A method for forming a microfluidic channel with improved flow characteristics for one or more analytes is disclosed. A microfluidic channel having modified surfaces is formed in fused silica. The fused silica surfaces are modified by the addition of a layer of borophosphosilicate glass. The addition of the borophosphosilicate glass results in an improved flow velocity profile of the analyte. As a result, control over the position and movement of analytes within the solution is improved.

摘要： A sensor for sensing a target chemical with high signal-to-noise ratio is disclosed. In some embodiments, the sensor comprises a sensing region that is optically coupled with an attenuation region. The sensing region receives optical stimulation that comprises light characterized by an excitation wavelength. In response to exposure to the target chemical, the sensing region fluoresces at a fluorescence wavelength. The attenuation region receives light from the fluorescing sensing region that includes light characterized by the fluorescence wavelength (i.e., signal) and light characterized by the excitation wavelength (i.e., noise). The attenuation region conveys the light to a detector that provides an electrical output signal based on the target chemical. While conveying the light, however, the attenuation region improves the signal-to-noise ratio by attenuating light characterized by the excitation wavelength more than light characterized by the fluorescence region.
