  • Publication number: 20020174686
    Abstract: A process for micromachining capillaries was having circular cross-sections in glass substrates. Microchannels are isotropically etched into a flat glass substrate, resulting in a semi-circular half-channel (or a rectangle with rounded corners). A second flat glass substrate is then fusion bonded to the first substrate, producing sealed microchannels with rounded bottom corners and a flat top surface having sharp corners. The process is completed by annealing at a sufficiently high temperature (approximately 750 C.) to allow surface tension forces and diffusional effects to lower the over-all energy of the microchannels by transforming the cross-section to a circular shape. The process can be used to form microchannels with circular cross-sections by etching channels into a glass substrate, then anodically bonding to a silicon wafer and annealing. The process will work with other materials such as polymers.

  • Patent number: 6437551
    Abstract: A microfabricated instrument for detecting and identifying cells and other particles based on alternating current (AC) impedance measurements. The microfabricated AC impedance sensor includes two critical elements: 1) a microfluidic chip, preferably of glass substrates, having at least one microchannel therein and with electrodes patterned on both substrates, and 2) electrical circuits that connect to the electrodes on the microfluidic chip and detect signals associated with particles traveling down the microchannels. These circuits enable multiple AC impedance measurements of individual particles at high throughput rates with sufficient resolution to identify different particle and cell types as appropriate for environmental detection and clinical diagnostic applications.
