    摘要: The present invention relates to methods and devices for separating particles according to size. More specifically, the present invention relates to a microfluidic method and device for the separation of particles according to size using an array comprising a network of gaps, wherein the field flux from each gap divides unequally into subsequent gaps. In one embodiment, the array comprises an ordered array of obstacles in a microfluidic channel, in which the obstacle array is asymmetric with respect to the direction of an applied field.

    摘要: The invention relates to a method for diagnosing an animal for a condition by obtaining a fluid sample from the animal, enriching a first analyte having a concentration of less than 1×10−3 analytes/μL from said sample by a factor of at least 10,000 fold; and analyzing one or more enriched first analytes to determine a condition in said animal. Enrichment is preferably performed using one or more size-based separation modules.

    摘要: The systems and methods herein involve the use of an automated, high-throughput system that utilizes pressure to transfer a fluid medium containing an analyte. In preferred embodiments, the sample is delivered to an analytical device. The sample can comprise one or more analytes, e.g., solvents, solutes, or particles, including rare cells. The systems are designed to minimize contact with potentially hazardous, fragile, or valuable samples. The systems allow for the dilution, mixing, and introduction of the fluid medium to an analytical device, followed by possible further analysis or sample manipulation. The systems and methods herein allow for partial or substantially complete depletion of a sample container to avoid wasting rare analytes or prevent retention of desired material in a first container.
