  • Patent number: 8715446
    Abstract: A latent solvent-based microfluidic apparatus and method involves laminate bonding of two non-elastomeric, cyclic olefin copolymer (COC) components having opposing surfaces to be bonded, wherein in a contacted state there is at least one interstitial space between the contacted surfaces, applying an organic latent solvent to at least one of the opposing surfaces, wherein the latent solvent is in an inactive state, contacting the two opposing surfaces together, actively removing the latent solvent from the at least one interstitial space; and adjusting a latent solvency parameter to activate the latent solvent, wherein the opposing contacted surfaces become bonded.

  • Publication number: 20120258516
    Abstract: An automated on-touch template bead preparation system is provided and includes a membrane-based emulsion generation subsystems, an emulsion PCR (ePCR) thermocycling plate and subsystem, and a continuous centrifugation emulsion breaking and templated bead collection subsystem. The emulsion generation subsystem provides uniformity in the preparation of an inverse emulsion and may be used to create large or small volume inverse emulsions rapidly and reproducibly. An emulsion-generating device is provided that can supply a continuous stream of an inverse emulsion to a thermocycling subsystem, in automated fashion. The ePCR subsystem can continuously thermocycle an inverse emulsion passed therethrough and includes static temperature zones and a consumable thermocycling plate. The continuous centrifugation subsystem can continuously break a thermally cycled inverse emulsion and collect template beads formed in the aqueous microreactor droplets of the inverse emulsion.

  • Publication number: 20120115738
    Abstract: A microfluidic device for analyzing a sample of interest is provided. The microfluidic device can comprise a microfluidic device body, wherein the microfluidic device body comprises a sample preparation area, a nucleic acid amplification area, a nucleic acid analysis area, and a network of fluid channels. Each of the sample preparation area, the nucleic acid amplification area and the nucleic acid analysis area are fluidly interconnected to at least one of the other two areas by at least one of the fluid channels. Using the microfluidic device, sample preparation can be combined with amplification of a biologically active molecule, and a suitable biological sample can be provided for analysis and/or detection of a molecule of interest. The small-scale apparatus and methods provided are easier, faster, less expensive, and equally efficacious compared to larger scale equipment for the preparation and analysis of a biological sample.

  • Patent number: 7837821
    Abstract: A method for making a polymeric microfluidic structure in which two or more components (layers) of the microfluidic structure are fixedly bonded or laminated with a weak solvent bonding agent, particularly acetonitrile or a mixture of acetonitrile and alcohol. In an aspect, acetonitrile can be used as a weak solvent bonding agent to enclose a microstructure fabricated in or on a non-elastomeric polymer such as polystyrene, polycarbonate, acrylic or other linear polymer to form a three-dimensional microfluidic network. The method involves the steps of wetting at least one of the opposing surfaces of the polymeric substrate components with the weak solvent bonding agent in a given, lower temperature range, adjacently contacting the opposing surfaces, and thermally activating the bonding agent at a higher temperature than the lower temperature range for a given period of time with RF or ultrasonic energy.
