Abstract:

In various aspects are provided a microfluidic and/or nanofluidic sensor that can provide an indication of the reliability of its measurement of the presence of an analyte in a sample under investigation, an analyte concentration in the sample under investigation, or both. The provided sensors, microfluidic devices, and methods of analyte detection, utilize two transduction mechanisms from the same molecule to determine analyte presence, analyte concentration, or both. An analyte sensing molecule is used that can provide both an optical signal and electrochemical signal when an analyte is recognized by an analyte binding portion of the sensing molecule.

Appl. No.:

12/668938

Inventors:

Christopher R. Lambert - Worcester MA, US

Assignee:

Worcester Polytechnic Institute - Worcester MA

International Classification:

G01N 21/64

US Classification:

2504591

Abstract:

The present invention is a low-cost, easily deployed, degradable taggant that can be dispersed over a wide area to serve as a witness to activity in the area and for queuing of other sensors. The taggant enables nearly real-time change detection within the treated area using one or more simple optical sensing techniques.

Filed:

Feb 6, 2002

Appl. No.:

10/066778

Inventors:

William Apruzzese - Everett MA, US
Pierre Trepagnier - Medford MA, US
Russell Gray - Brownsburg IN, US
James Mansfield - Boston MA, US
Christopher Lambert - Hudson MA, US

International Classification:

A61B006/00

US Classification:

600/477000

Abstract:

The invention relates to fluorescence calibration devices and methods that can mimic skin and other tissues. A calibration device of the invention comprises at least one scattering layer, which is preferably non-fluorescent, and a second layer containing one or more fluorophore. Light passes through the scattering layer and excites the fluorophore. Light emitted from the fluorophore passes back though the scattering layer and into collecting optics, which can be measured and that measurement used to correct for instrument drift.

Inventors:

Jerome Workman - Brookline MA, US
Christopher Lambert - Hudson MA, US

International Classification:

C12Q001/54

US Classification:

435/014000

Abstract:

This invention provides devices, compositions and methods for determining the concentration of one or more metabolites or analytes in a biological sample, including cells, tissues, organs, organisms, and biological fluids. In particular, this invention provides materials, apparatus, and methods for several non-invasive techniques for the determination of in vivo blood glucose concentration levels based upon the in vivo measurement of one or more analytes or parameters found in skin.
