Quantum Dot Conjugates In A Sub-Micrometer Fluidic Channel

View page
US Patent:
7695988, Apr 13, 2010
Filed:
Jun 20, 2008
Appl. No.:
12/143334
Inventors:
Samuel M. Stavis - Ithaca NY, US
Joshua B. Edel - Brookline MA, US
Kevan T. Samiee - Ithaca NY, US
Harold G. Craighead - Ithaca NY, US
Assignee:
Cornell Research Foundation, Inc. - Ithaca NY
International Classification:
G01R 31/26
H01L 21/66
US Classification:
438 14, 438962, 257E29071, 977700, 977774
Abstract:
A nanofluidic channel fabricated in fused silica with an approximately 500 nm square cross section was used to isolate, detect and identify individual quantum dot conjugates. The channel enables the rapid detection of every fluorescent entity in solution. A laser of selected wavelength was used to excite multiple species of quantum dots and organic molecules, and the emission spectra were resolved without significant signal rejection. Quantum dots were then conjugated with organic molecules and detected to demonstrate efficient multicolor detection. PCH was used to analyze coincident detection and to characterize the degree of binding. The use of a small fluidic channel to detect quantum dots as fluorescent labels was shown to be an efficient technique for multiplexed single molecule studies. Detection of single molecule binding events has a variety of applications including high throughput immunoassays.

US Patent:
8435415, May 7, 2013
Filed:
Nov 24, 2009
Appl. No.:
12/625077
Inventors:
Samuel Martin Stavis - North Potomac MD, US
Elizabeth Arlene Strychalski - North Potomac MD, US
Michael Gaitan - North Potomac MD, US
Assignee:
The United States of America, as represented by the Secretary of Commerce, the National Institute of Standards and Technology - Washington DC
Cornell University—Cornell Center for Technology, Enterprise & Commercialization - Ithaca NY
International Classification:
B44C 1/22
C23F 1/00
US Classification:
216 41, 216 2, 216 58, 216 67, 430 5, 430313
Abstract:
A nanofabrication process for use with a photoresist that is disposed on a substrate includes the steps of exposing the photoresist to a grayscale radiation pattern, developing the photoresist to remove a irradiated portions and form a patterned topography having a plurality of nanoscale critical dimensions, and selectively etching the photoresist and the substrate to transfer a corresponding topography having a plurality of nanoscale critical dimensions into the substrate.

US Patent:
20170348686, Dec 7, 2017
Filed:
Jun 1, 2017
Appl. No.:
15/611557
Inventors:
- Gaithersburg MD, US
SAMUEL M. STAVIS - NORTH POTOMAC MD, US
GLENN E. HOLLAND - ROCKVILLE MD, US
International Classification:
B01L 3/00
G01N 23/04
G01N 35/00
G01N 1/28
B01L 9/00
G01N 27/447
Abstract:
A fluid sampler includes: a sample cell that includes: a substrate comprising: a first port; a second port in fluid communication with the first port; a viewing reservoir in fluid communication with the first port and the second port and that receives the fluid from the first port and communicates the fluid to the second port, the viewing reservoir including : a first view membrane; a second view membrane; and a pillar interposed between the first view membrane and second view membrane, the pillar separating the first view membrane from the second view membrane at a substantially constant separation distance such that a volume of the viewing reservoir is substantially constant and invariable with respect to a temperature and invariable with respect to a pressure to which the sample cell is subjected.
