A61B 19/00
A61B 17/08
A61B 17/04
A61L 17/00
A61F 2/16
A61F 2/18
US Classification:
523111, 128849, 606151, 606213, 606215, 606231, 623 663, 623 10

Opto-Fluidic Nanoparticle Detection Apparatus

View page
US Patent:
8537356, Sep 17, 2013
Filed:
Mar 2, 2009
Appl. No.:
12/920262
Inventors:
H. Daniel Ou-Yang - Bethlehem PA, US
Xuanhong Cheng - Bethlehem PA, US
Assignee:
Lehigh University - Bethlehem PA
International Classification:
G01N 21/00
US Classification:
356338, 356300, 356344, 356369, 250225
Abstract:
Provided herein are new methods and apparatus for quantitative measurement and analysis of particles, including new apparatus systems to process and detect nanoparticles in suspension. By focusing a laser beam at the center of a reservoir, nanoparticles are concentrated by optical energy, and fluorescent intensity at the focal point of the laser is measured to quantify particle concentration in the reservoir. The techniques may be applied to the analysis of suspensions of nanoparticles, including natural particles (e. g. , microorganisms including whole viruses, bacteria, animal cells, and proteins) and synthetic particles (e. g. , colloidal latexes, paints, pigments, and metallic or semiconductor nanoparticles) for medical and industrial applications, among others.

Apparatus And Methods For Binding Molecules And Cells

View page
US Patent:
20040053334, Mar 18, 2004
Filed:
Jul 29, 2003
Appl. No.:
10/630235
Inventors:
Buddy Ratner - Seattle WA, US
Xuanhong Cheng - Seattle WA, US
Karl Bohringer - Seattle WA, US
Yanbing Wang - Seattle WA, US
Yael Hanein - Tel-Aviv, IL
Ashutosh Shastry - Bellevue WA, US
International Classification:
G01N033/53
C12M001/34
US Classification:
435/007100, 435/287200
Abstract:
In one aspect, the present invention provides devices for binding cells or molecules, wherein each device includes (a) a body defining a first surface and a second surface that is located opposite to the first surface; (b) a heater disposed upon the first surface; and (c) a temperature-responsive layer disposed upon the second surface. In another aspect, the present invention provides methods for binding molecules or living cells to a temperature-responsive material.

Devices And Methods For Detecting Cells And Other Analytes

View page
US Patent:
20090298067, Dec 3, 2009
Filed:
Mar 15, 2007
Appl. No.:
12/293046
Inventors:
Daniel Irimia - Charlestown MA, US
Xuanhong Cheng - Charlestown MA, US
Mehmet Toner - Wellesley MA, US
Utkan Demirci - Cambridge MA, US
William Rodriguez - Arlington MA, US
International Classification:
C12Q 1/68
C12N 5/00
C12Q 1/02
C12M 1/00
US Classification:
435 6, 435325, 435 29, 4352831
Abstract:
The invention features methods, devices, and kits for the isolation of analytes (e.g., a cell). A sample containing a desired analyte is introduced into a microfluidic device containing moieties that bind the desired analyte. A shear stress is applied that is great enough to prevent binding of undesired analytes and low enough to allow binding of the analyte of interest. Once bound, the desired analytes can be analyzed (e.g., counted). The invention also features methods for determining a shear stress for isolating a desired analyte.

Methods For Counting Cells

View page
US Patent:
20120003687, Jan 5, 2012
Filed:
Apr 21, 2008
Appl. No.:
12/596768
Inventors:
Mehmet Toner - Wellesley MA, US
Rashid Bashir - Champaign IL, US
Xuanhong Cheng - Charlestown MA, US
Utkan Demirci - Cambridge MA, US
Daniel Irimia - Charlestown MA, US
William R. Rodriguez - Cambridge MA, US
Liju Yang - Apex NC, US
Lee Zamir - Cambridge MA, US
Yi-Shao Liu - Champaign IL, US
International Classification:
C12Q 1/06
US Classification:
435 39
Abstract:
The invention features methods of quantifying cells in a sample by lysing the cells followed by the measurement of at least one intracellular component. Methods of the invention are especially useful for quantifying small numbers of cells, e.g., over a large surface area or volume compared to the cell size. In a preferred embodiment, methods of the invention are performed using a microfluidic device.

Counting Particles Using An Electrical Differential Counter

View page
US Patent:
20130295588, Nov 7, 2013
Filed:
Nov 9, 2011
Appl. No.:
13/884580
Inventors:
Nicholas Watkins - Attleboro MA, US
Rashid Bashir - Champaign IL, US
William Rodriguez - Cambridge MA, US
Xuanhong Cheng - Bethlehem PA, US
Mehmet Toner - Wellesley MA, US
Grace Chen - Cambridge MA, US
Aaron Oppenheimer - Cambridge MA, US
Assignee:
THE GENERAL HOSPITAL CORPORATION - Boston MA
THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOIS - Urbana IL
MASSACHUSETTS INSTITUTE OF TECHNOLOGY - Cambridge MA
International Classification:
G01N 27/02
US Classification:
435 724, 4352872, 702 19
Abstract:
This disclosure relates to methods and devices to count particles of interest, such as cells. The methods include obtaining a fluid sample that may contain particles of interest; counting all types of particles in a portion of the sample using a first electrical differential counter to generate a first total; removing any particles of interest from the portion of the fluid sample; counting any particles remaining in the portion of the fluid sample using a second electrical differential counter after the particles of interest are removed to generate a second total; and calculating a number of particles of interest originally in the fluid sample by subtracting the second total from the first total, wherein the difference is the number of particles of interest in the sample. These methods and related devices can be used, for example, to produce a robust, inexpensive diagnostic kit for CD4+ T cell counting in whole blood samples.
