    摘要： A channel-less microfluidic pump includes a cartridge including a substrate and an actuatable film layer disposed on the substrate, and a manifold having at least three actuatable void volumes separated by a plurality of wall sections and an actuatable flexible layer disposed on the manifold interfacing the actuatable film layer. In operation, the pump can be in an unactuated state wherein the actuatable film layer is disposed against the surface of the substrate or an actuated state wherein at least a portion of the flexible layer and a corresponding portion of the actuatable film layer are deflected into a corresponding void volume thus forming a fluidic volume between the deflected portion of the actuatable film layer and the surface of the substrate. In the actuated state, there is a fluidic gap between immediately adjacent void volumes formed by a thinned region of the flexible layer at a point of contact with a top surface of a wall section. A method of transporting fluid using the channel-less microfluidic pump is described.

    摘要： A microfluidic apparatus, method, and associated applications utilize and apply to a formalin-fixed paraffin-embedded (FFPE) tissue sample and performing a liquid-liquid extraction to remove the paraffin from the tissue sample prior to a nucleic acid purification step. A microfluidic device includes a dedicated liquid-liquid extraction process vessel, a nucleic acid purification process component, and a nucleic acid amplification reactor. A liquid-liquid extraction and nucleic acid purification kit includes a microfluidic device capable of performing both a liquid-liquid extraction process and a nucleic acid purification process, including a dedicated liquid-liquid extraction process vessel, an immiscible liquid or a precursor phase thereof disposed in the vessel, a nucleic acid purification process component, a nucleic acid amplification reactor fluidically, and a supply of reagents suitable to enable the liquid-liquid extraction process and the nucleic acid purification process.

    摘要： Methods and systems for selectively amplifying a target DNA sequence in the presence of non-target DNA sequence in a sample, comprising: contacting the sample with an oligonucleotide system under hybridization conditions to form a reaction mixture including a forward primer and a reverse primer, wherein either the forward or reverse primer is modified to preferentially increase hybridization between the primer and the target sequence; cycling the hybridization of the oligonucleotide system so that, if the target DNA sequence is present in the sample, the primers hybridize to the target DNA sequence and the reaction mixture results in a first amplified product; and detecting the first amplified product.
