  • Microfluidic devices with monolithic microwave integrated circuits
    Patent number: 6605454
    Abstract: A microwave device has a monolithic microwave integrated circuit (MMIC) disposed therein for applying microwave radiation to a microfluidic structure, such as a chamber, defined in the device. The microwave radiation from the MMIC is useful for heating samples introduced into the microfluidic structure and for effecting lysis of cells in the samples. Microfabrication techniques allow the fabrication of MMICs that perform heating and cell lysing of samples having volumes in the microliter to picoliter range.
    Type: Grant
    Filed: March 22, 2001
    Date of Patent: August 12, 2003
    Assignee: Motorola, Inc.

  • Integrated multilayered microfludic devices and methods for making the same
    Patent number: 6572830
    Abstract: A multilayered microfluidic device having a substantially monolithic structure is formed by sintering together a plurality of green-sheet layers. The substantially monolithic structure has an inlet port for receiving fluid, an outlet port for releasing fluid, and an interconnection between the inlet port and the outlet port. The substantially monolithic structure may also include a variety of components to enable useful interaction with the fluid, such as electrically conductive pathways, heaters, fluid sensors, fluid motion transducers, and optically transmissive portions. The components are preferably fabricated using thick-film or green-sheet technology and are preferably co-fired with and sintered to the green-sheet layers to become integral with the substantially monolithic structure.

  • System and methods for mixing within a microfluidic device
    Publication number: 20030064507
    Abstract: The present invention provides microfluidic systems comprising microfluidic chambers and mixers, and methods of use. The microfluidic chambers of the present invention comprise a flexible membrane which provides efficient mixing of the solution therein. The present invention also provides a microfluidic chamber in fluidic communication with a micro-disk and a microfluidic chamber comprising a shim such that and a contiguous gap is present between a sample fluid and the chamber membrane. The microfluidic systems find use in the decrease in time for reactions occurring therein.
