In one embodiment, a multiplex fluid processing cartridge includes a sample well, a deformable fluid chamber, a mixing well with a mixer disposed therein, a lysis chamber including a lysis mixer, an electrowetting grid for microdroplet manipulation, and electrosensor arrays configured to detect analytes of interest. An instrument for processing the cartridge is configured to receive the cartridge and to selectively apply thermal energy, magnetic force, and electrical connections to one or more discrete locations on the cartridge and is further configured to compress the deformable chamber(s) in a specified sequence.

Processing cartridge and method for detecting a pathogen in a sample

Methods, devices, and systems for performing polymerase chain reaction (PCR) amplification and melt data acquisition according to a single slug approach in which a single slug in a microfluidic channel fills an entire thermal zone of the microfluidic channel, and the thermal zone used for both PCR temperature cycling and melt data acquisition. A detector may be configured to detect fluorescence from the thermal zone during the PCR temperature cycling for real-time PCR and/or during temperature ramping in the melt data acquisition. Slug position control may be achieved by detecting leading or trailing edges in a slug build target zone into which a slug passes after passing through the thermal zone. The single slug approach may break coupling between one or more events of the PCR amplification and melt data acquisition and enable events to be independently optimized.

Methods, devices, and systems for processing multiple assays

The present invention relates to systems and methods for the real time processing of nucleic acid during polymerase chain reaction (PCR) and thermal melt applications. According to an aspect of the invention, a system for the rapid serial processing of multiple nucleic acid assays is provided. In one embodiment, the system includes, but is not limited to: a microfluidic cartridge having microfluidic (flow-through) channels, a fluorescence imaging system, a temperature measurement and control system; a pressure measurement and control system for applying variable pneumatic pressures to the microfluidic cartridge; a storage device for holding multiple reagents (e.g., a well-plate); a liquid handling system comprising at least one robotic pipettor for aspirating, mixing, and dispensing reagent mixtures to the microfluidic cartridge; systems for data storage, processing, and output; and a system controller to coordinate the various devices and functions.

Instrument and cartridge for performing assays in a closed sample preparation and reaction system employing electrowetting fluid manipulation

In one aspect, the present invention provides methods, devices, and systems for ensuring that multiple components of a mixture are fully mixed in a continuous flow microfluidic system while ensuring that mixing between segments flowing through the chip is minimized. In some embodiments, the present invention includes mixing fluids in a droplet maintained at the tip of a pipette before the mixture is introduced to the microfluidic device. In another aspect, the present invention provides a pipette tip having a ratio of an outside diameter to an inside diameter that provides sufficient surface area for a droplet comprising up to the entire volume of the liquid to suspend from the pipette tip intact. In yet another aspect, the present invention provides methods, devices, and systems for delivering a reaction mixture to a microfluidic chip comprising a docking receptacle, an access tube and a reservoir.

Systems for processing multiple assays background

The present invention, in one aspect, provides methods and systems for controlling slugs using temperature dependent fluorescent dyes. In some embodiments, the present invention uses one or more techniques to enhance the visibility of slugs, enhance a system's ability to differentiate between slugs, and enhance a system's ability to identify the positions of slugs.

Instrument for processing cartridge for performing assays in a closed sample preparation and reaction system

A sample-containing device configured to be placed into a sample processing instrument for performing a process on a sample contained in the device includes redundant identification features, such as machine-readable tags. A first machine-readable information tag is read before the device is placed in the instrument, and a second machine-readable information tag is read after the device is in the instrument. Information read from the two tags is compared to determine if there is proper correspondence between the information read from the tags to ensure that the correct sample processing device was placed in the instrument.

The present invention relates to systems and methods for minimizing or eliminating diffusion effects. Diffused regions of a segmented flow of multiple, miscible fluid species may be vented off to a waste channel, and non-diffused regions of fluid may be preferentially pulled off the channel that contains the segmented flow. Multiple fluid samples that are not contaminated via diffusion may be collected for analysis and measurement in a single channel. The systems and methods for minimizing or eliminating diffusion effects may be used to minimize or eliminate diffusion effects in a microfluidic system for monitoring the amplification of DNA molecules and the dissociation behavior of the DNA molecules.
