Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G01K 17/00

US Classification:

374 31

Abstract:

A system for performing cantilever based calorimetric analysis system. A laser device is configured to emit a beam of laser energy along a beam pathway reaching from the laser device to a microcantilever. The microcantilever presents a reflective target area for the laser beam. The microcantilever deflects in response to heat. A material is provided adjacent to the target area. The material receives heat energy from the laser beam. A detector is positioned on a beam return pathway. The detector is configured to sense laser energy from the beam return pathway and provide a data single that represents calorimetric data from the material. Control circuitry is also provided to receive the data signal from the detector and process the data signal according to program logic for providing a differential scanning calorimetric analysis of the calorimetric data. An associated method of use is also provided.

International Classification:

G03F 7/00
H01B 13/00
C03C 15/00

G01N 1/00

US Classification:

436174, 430320, 216 16, 216 41, 216 59

Abstract:

Provided is a sensor array and a method of forming the same. The sensor array includes an array of apertures etched into a 3D patterned resist layer to expose areas of one or more agents and/or reagents deposited on a substrate. The sensor is formed using a Self-Aligned Imprint Lithography (“SAIL”) method, a process that allows for a one-time deposition of all required materials followed by a series of etching/cleaning steps. The location of reagents on the sensor template, as well as the concentration gradient of each reagent, may be controlled through the sensor manufacturing process. Bores of a single reagent, or bores containing two or more reagents, may be formed using the SAIL process.

Appl. No.:

Inventors:

Manish Sharma - Palo Alto CA, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G01J 3/30

US Classification:

356317

Abstract:

Provided is a system for characterizing biological/chemical test specimens. In particular, a container such as a tube or capillary for containing a test specimen is interconnected at one end to a light source via a fiber optic. A second end of the tube is connected to a detector via a second fiber optic. In one embodiment, the containing tube exhibits “total internal reflection”. As light is projected into the tube, one or more electric fields are applied to the specimen. Light travels the length of the tube to excite specimen molecules, which subsequently emit light having a wavelength longer than that of the projected light. The emitted light travels the length of the tube, is detected, and is then transmitted to a processor for analysis. In an alternate embodiment, the tube is not TIR therefore emitted light exits the tube along its length, wherein it is detected by one or more detectors.

Abstract:

The present invention provides a method of fabricating a biosensor. The method includes providing a substrate which has a surface coating. The surface coating is deformable and the substrate includes a layered structure which has at least two electrically conductive layers separated by at least one electrically insulating layer. The method also includes imprinting a structure into the surface coating. Further, the method includes etching at least a region of the imprinted structure and the substrate to remove at least a portion of the structure and the substrate. The structure is shaped so that the etching forms at least a portion of the biosensor in the substrate and exposes at least a portion of each electrically conductive layer to form electrodes of the biosensor.
