    摘要： A fluidic structure includes a channel and along the channel is a series of sensing components to obtain information about objects traveling within the channel, such as droplets or other objects carried by fluid. At least one sensing component includes a set of cells of a photosensor array. The set of cells photosense a range of photon energies that emanate from objects, and include a subset of cells that photosense within subranges. A processor can receive information about objects from the sensing components and use it to obtain spectral information. The processor can perform an initial analysis using information from one set of sensing components and, based on the results, control a fluidic device in the channel, such as a gate, to retain objects, such as for concentration and more detailed analysis by other sensing components, or to purge objects from the channel.

    摘要： A sample manipulator that utilizes electrostatic traveling waves to selectively displace one or more samples deposited on its face is disclosed. The sample manipulator enables an operator to perform a wide variety of processes upon the deposited samples. Also disclosed are strategies for separating two or more samples, focusing a sample, and passing a reagent through a sample, all conducted on the face of the sample manipulator.

    摘要： Several traveling wave grid systems are disclosed that may be used to concentrate and form highly localized regions of bio-agents or other charged species. In addition, specific detection systems are described that enable currently available detectors and sensors, including those to be developed in the future, to be used for measuring the presence and concentration of certain bio-agents or charged particles, which otherwise are present at concentrations too low to readily detect or measure.

    摘要： Various systems and techniques are disclosed for stopping, selectively controlling, and optimizing a flow of particles in a flowing stream. The systems and techniques utilize a multi-electrode assembly and various voltage waveforms applied to those electrodes. The particles flow past or near the electrode assembly and their flow is controlled by the configuration and arrangement of the electrodes and the voltage waveforms applied thereto. An additional strategy for countering particle leakage flow is also described.

    摘要： A portable apparatus for extracting and concentrating bioagents within a fluid medium includes a container with sample solution inlet port and traveling wave grids patterned on surfaces of the container. The traveling wave grids cause bioagents to migrate to a specified surface within the container and then to an extraction port. The traveling wave grids include a substrate, across which extend a collection of closely spaced and parallel electrically conductive electrodes, and a collection of buses providing electrical communication with the collection of conductive electrodes. A voltage controller provides a multiphase electrical signal to the collection of buses and electrodes of the traveling wave grids.
