    摘要: A method is provided for acoustically ejecting from a channel or other container a plurality of fluid droplets, each of which contains one or more particles or other localized volumes. The localized volumes, which can be living cells, are ejected towards sites on a substrate surface, a container, or a channel. An integrated cell sorting and arraying system is also provided that is capable of sorting based upon cellular properties by the selective ejection of cells from a carrier fluid. The cells can be ejected with adjustable velocity and trajectory. The ejected cells can be directed to form an array, wherein each site of the array can contain a single cell. Additionally provided is a method of forming arrays of single live cells more efficiently, rapidly, flexibly, and economically than by other cell array approaches. This method permits efficient, continuous, and simultaneous sorting of cells based upon the quantitative or semiquantitative measurement of cellular properties, and also permits non-binary or severally-branched decision-making. An integrated system, which includes a processor, and methods are also provided for the detection, selection, and ejection of selected particles or circumscribed volumes, such as live cells, from a continuous stream of fluid-suspended particles or other circumscribed volumes flowing in channels.

    摘要: Provided is a method of transporting fluid which involves acoustic ejection into a small opening. The opening may be, for example, the inlet opening of a sample vessel. Alternatively, it may be an opening in a microfluidic device. The ejection is typically, but not necessarily carried out through the application of focused acoustic energy. The fluid being transported typically comprises a moiety of interest for analysis or further processing, which may be a biomolecule. The volumes of transported fluid may be in the nanoliter or picoliter range. Ejection may occur from very small volumes and the ejected droplet may carry away a significant fraction of the volume from which ejection occurs.

    摘要: Provided is a method for preparing a sample surface for analysis that involves placing a sample surface in droplet-receiving relationship to a reservoir containing an analysis-enhancing fluid. Typically, the analysis-enhancing fluid is comprised of a mass spectrometry matrix material and a carrier fluid, and the carrier fluid is comprised of a low volatility solvent. A droplet of the analysis-enhancing fluid from the reservoir such that the droplet is deposited on the sample surface at a designated site. Such ejection is typically, but not necessarily carried out through the application of focused acoustic energy. Then, the sample is subjected to conditions sufficient to allow the analysis-enhancing fluid to interact with the sample surface to render the sample surface suitable for analysis. Optionally, the sample is analyzed at the selected site. Also provided are systems and devices for preparing a sample surface for analysis.

    摘要: Devices and methods are provided for reducing the uncontrolled electrostatic charges that can alter the volume and/or trajectory of a droplet, which is typically ejected through the application of focused acoustic radiation. Also provided are reservoirs and substrates, e.g., well plates formed from a material that is at least partially nonmetallic or polymeric and either has an electrical resistivity of no more than about 1011 ohm-cm, has a surface electrical resistivity of no more than about 1012 ohm/sq, or both.
