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.

US Classification:

4351737, 219690, 219691, 219692, 219693, 422 22

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.

International Classification:

G01N027/26

US Classification:

204/403130, 204/403140

Abstract:

This invention relates to the detection of molecular interactions between biological molecules. Specifically, the invention relates to electrical detection of interactions such as hybridization between nucleic acids or peptide antigen-antibody interaction using arrays of peptides or oligonucleotides. In particular, the invention relates to an apparatus and methods for detecting nucleic acid hybridization or peptide binding using electronic methods including AC impedance. In some embodiments, no electrochemical or other label moieties are used. In others, electrochemically active labels are used to detect reactions on hydrogel arrays, including genotyping reactions such as the single base extension reaction.
