Abstract:
A biosensor detection system for detecting a particular substance has at least two biosensor devices. Each biosensor device includes a piezoelectric material, an input transducer mounted on the piezoelectric material to receive an input radio frequency signal and propagate a corresponding acoustic wave within the piezoelectric material and an output transducer mounted on the piezoelectric material to receive the acoustic wave and transmit a corresponding output radio frequency signal. A biolayer is mounted on the piezoelectric material to receive a substance to be tested and cause a corresponding change in the acoustic wave. An oscillator circuit is connected to the input transducer and to the output transducer, the oscillator circuit including an amplifier and providing an output signal indicative of a change in the acoustic wave. The biosensor devices having two different biolayers, whereby the output signals can be utilized to detect receipt of a particular substance by the biolayers of the biosensor devices.

A method of incorporating biomolecules in a thin film mounted on a substrate, with the film having a thickness of not more than about 10 microns, includes providing a metal structure on the substrate between the thin film and the substrate, positioning a medium containing biomolecules in contact with a side of the film remote from the metal substrate, and applying a predetermined electrical voltage between the metal substrate and the medium to cause biomolecules to migrate in an electrophoretic manner from the medium into the thin film.
Abstract:
A portable microwave plasma discharge unit receives microwaves and a gas flow via a supply line. The portable microwave plasma discharge unit generates plasma from the gas flow and the received microwaves. The portable microwave plasma discharge unit includes a gas flow tube made of a conducting and/or dielectric material and a rod-shaped conductor that is axially disposed in the gas flow tube. The rod-shaped conductor has an end configured to contact a microwave supply conductor of the supply line to receive microwaves and a tapered tip positioned adjacent the outlet portion of the gas flow tube. The tapered tip is configured to focus the microwaves received from the microwave supply conductor to generate plasma from the gas flow.
Abstract:
Systems and methods for generating relatively cool microwave plasma. The present invention provides a microwave plasma nozzle that includes a gas flow tube through which a gas flows, and a rod-shaped conductor that is disposed in the gas flow tube and has a tapered tip near the outlet of the gas flow tube. A portion of the rod-shaped conductor extends into a microwave cavity to receive microwaves passing in the cavity. These received microwaves are focused at the tapered tip to heat the gas into plasma. The microwave plasma nozzle also includes a vortex guide between the rod-shaped conductor and the gas flow tube imparting a helical shaped flow direction around the rod-shaped conductor to the gas flowing through the tube. The microwave plasma nozzle further includes a mechanism for electronically exciting the gas and a shielding mechanism for reducing a microwave power loss through the gas flow tube.
