Abstract: The present invention provides a microfluidic system, method and kit for performing assays. The system may comprise a microfluidic device and a detector, wherein the assay yields results that may be read by a detector and analyzed by the system. The assay may comprise one or more chemical or biological reaction against, or performed on, a sample or multiple samples. The sample(s) may become larger and/or smaller during the performance of the assay. The sample(s) may be present within a vehicle, or on a carrier within a vehicle, in the microfluidic device, and wherein the vehicle may become larger and/or smaller during the performance of the assay. The assay may be a cascading assay comprising a series of multiple assays, wherein each assay may be the same or different, and wherein each assay in the series of multiple assays may further comprise one or more process or step.

Abstract: The present invention generally pertains to a system which utilizes floating thermal contact to enable PCR, in a thermal management device. Comprised of multiple thermal zones attached to a framework, each zone an individually actuated, isolated sub-assembly. The actuation of each zone ensures physical contact with an uneven, yet flat microfluidic chip to achieve effective, conductive heat transfer. The isolation of each zone serves to insulate the thermal zones from each other and minimize undesired heat transfer between adjacent zones, so that each zone is at a proper, uniform temperature.

Abstract: The present invention generally pertains to a system for performing droplet inflation, and methods and kits comprising the same. The system comprises at least one microfluidic channel comprising one or more droplets flowing therein, one or more fluid reservoirs, one or more inflators, one or more inflator nozzles, and at least one mechanism for disrupting an interface between a droplet and a fluid. The present invention provides for the inflation of a relatively controlled volume of fluid into a droplet resulting in an increase in the volume of the droplet relative to its volume prior to inflation and, accordingly, dilution of the concentration of species, if any, previously present and emulsified in the droplet.

Abstract: The present invention generally pertains to methods and kits for managing the variation in spectroscopic intensity measurements through the use of a reference component. The reference component may comprise a reference spectroscopic substance and may be contained together with a sample of interest in a sample to be tested, wherein the sample of interest may comprise a sample spectroscopic substance. Each sample to be tested may be uniquely identified and, hence, “barcoded” by combinations of different colors and concentrations of spectroscopic substances, contained therein.
