    摘要: The present invention provides exchangeable, reagent pre-loaded carriers (10), preferably in the form of plastic sheets, which can be temporarily applied to an electrode array (16) on a digital microfluidic (DMF) device (14). The carrier (10) facilitates virtually un-limited re-use of the DMF devices (14) avoiding cross-contamination on the electrode array (16) itself, as well as enabling rapid exchange of pre-loaded reagents (12) while bridging the world-to-chip interface of DMF devices (14). The present invention allows for the transformation of DMF into a versatile platform for lab-on-a-chip applications.

    摘要: Methods are provided for the preparation of a sample using a digital microfluidic platform and the optional subsequent mass analysis of an extracted analyte. A sample is dried, optionally on a solid phase support, and contacted with digital microfluidic array. An analyte present within the dried sample is extracted into an extraction solvent by electrically addressing the digital microfluidic array to transport a droplet of extraction solvent to the dried sample spot. The extracted sample may be dried and subsequently processed on the digital microfluidic array for derivatization. The digital microfluidic device may further include an integrated microfluidic channel having an output aperture, and the method may further include contacting a droplet containing extracted analyte with the microfluidic channel and applying a suitable electric field for generating nano-electrospray, thereby enabling the device to be directly interfaced with a mass analysis device.

    摘要: Devices and methods are provided for performing droplet-based solid phase processing steps on a digital microfluidic device. A solid phase material, which may be a porous solid phase material such as a porous polymer monolith is formed or located on a digital microfluidic element. The solid phase may be formed by an in-situ method in which the digital microfluidic array is actuated to transport a droplet of solid phase pre-cursor solution to a selected element on the array, and subsequently processed to form a solid phase on the array element. The integration of a solid phase material with a digital microfluidic array enables a wide range of applications including solid phase extraction and sample concentration.
