Glucose Biosensor

View page
US Patent:
6475750, Nov 5, 2002
Filed:
Aug 23, 2000
Appl. No.:
09/644323
Inventors:
In Suk Han - Salt Lake City UT
You Han Bae - Salt Lake City UT
Dal Young Jung - Salt Lake City UT
Jules John Magda - Salt Lake City UT
Assignee:
M-Biotech, Inc. - Salt Lake City UT
International Classification:
C12Q 154
US Classification:
435 14, 435 26, 4352871, 436 95, 436148, 6048911, 6048921
Abstract:
A biosensor ( ) has a hydrogel ( ) in a rigid and referably biocompatible enclosure ( ). The hydrogel ( ) includes an immobilized glucose-binding molecule such as concanavalin A (Con A) and an immobilized hexose saccharide such as a-D-mannopyranoside. The immobilized hexose saccharide competitively binds with free glucose to the glucose-binding molecules, thus changing the number of crosslinks in the hydrogel ( ), which changes hydrogel swelling tendency and the pressure of the hydrogel in its confined space in proportion to the concentration of free glucose. By measuring the change in hydrogel pressure with a pressure transducer ( ), the biosensor ( ) is able to accurately measure the concentration of the tree glucose molecule without the problem of oxygen limitations and interference encountered by prior art biosensors. A battery ( ) powered telemeter ( ) operably engaged to the pressure transducer ( ) sends a radio data signal to a receiver ( ) containing an alarm system operably attached to a computer ( ). Furthermore, an alarm system utilizes such a sensor to automatically notify a person that the blood glucose level is outside a predetermined parameter, and/or to automatically inject an agent such as glucose or glycogen which will raise blood glucose levels.

Filed:
Apr 20, 2001
Appl. No.:
09/839993
Inventors:
In Suk Han - Sandy UT
Jules John Magda - Salt Lake City UT
Seok Lew Lew - Salt Lake City UT
Young San Jean - Seoul, KR
Assignee:
M-Biotech, Inc. - Salt Lake City UT
International Classification:
C12Q 100
US Classification:
435 4, 4352871, 4352877, 6048911, 6048921
Abstract:
A biosensor ( ) has a hydrogel ( ) in a rigid and preferably biocompatible enclosure ( ). The hydrogel ( ) includes an immobilized analyte binding molecule (ABM) and an immobilized analyte. The immobilized analyte competitively binds with free analyte to the ABM, thus changing the number of crosslinks in the hydrogel ( ), which changes hydrogel swelling tendency (and thus the osmotic pressure) in its confined space in proportion to the concentration of free analyte concentration. By measuring the change in hydrogel pressure with a pressure transducer ( ), the biosensor ( ) is able to accurately measure the concentration of the free analyte molecule without the problem of oxygen limitations and interference encountered by prior art biosensors. A battery ( ) powered telemeter ( ) operably engaged to the pressure transducer ( ) sends a radio data signal to a receiver ( ) containing an alarm system operably attached to a computer ( ). Furthermore, an alarm system utilizes such a sensor to automatically notify a person that the analyte level is outside desired predetermined parameters, and/or to automatically inject an agent to counteract the adverse analyte levels.

US Patent:
62681613, Jul 31, 2001
Filed:
May 11, 1999
Appl. No.:
9/308392
Inventors:
In Suk Han - Salt Lake City UT
You Han Bae - Salt Lake City UT
Jules J. Magda - Salt Lake City UT
Seong Gi Baek - Woodbury MN
Assignee:
M-Biotech, Inc. - Salt Lake City UT
International Classification:
C12Q 154
C12M 134
US Classification:
435 14
Abstract:
A biosensor (10) has a pH-sensitive polymeric hydrogel (30) in a rigid and preferably biocompatible enclosure (20). The hydrogel (30) includes an immobilized oxidoreductase enzyme such as glucose oxidase. The oxidoreductase enzyme catalyzes a chemical reaction consuming an organic molecule and producing a byproduct. The hydrogel (30) changes its osmotic pressure in proportion to the concentration of a byproduct. By measuring the change in osmotic pressure with a pressure transducer (40), the biosensor (10) is able to accurately measure the concentration of the organic molecule without the problem of interference encountered by prior art biosensors. A battery (64) powered telemeter (60) operably engaged to the pressure transducer (40) sends a radio data signal to a receiver (66) operably attached to a computer (62).

Abstract:
Microresonator structures including a top polymer film layer, a bottom polymer film layer, and a smart hydrogel structure sandwiched between the polymer film layers. An ultrasound resonator cavity having a resonance frequency is defined between the top and bottom polymer layers, and the smart hydrogel structure is configured to provide a change in height to the ultrasound resonator cavity due to volumetric expansion or contraction of the smart hydrogel structure, in response to interaction of the smart hydrogel structure with one or more predefined analytes in an in vivo or other environment. Related methods of use for determining the presence or concentration of a given target analyte, as well as methods of fabricating such microresonator structures are also described.

G10K 11/04
A61B 8/08
Abstract:
Systems and methods for measuring changes in smart hydrogel microresonator structures positioned in an in vivo or other environment, having an acoustic resonance frequency in an ultrasound range. The system includes a smart hydrogel microresonator structure positioned within the environment configured to exhibit a change in resonance frequency in response to interaction with one or more predefined analytes in the environment. The system includes an ultrasound transducer for querying the smart hydrogel microresonator structure at or near its resonance frequency. The system also includes a computer system configured to receive ultrasound data as provided by query of the smart hydrogel microresonator structure and to determine changes in resonance frequency, amplitude or intensity of the ultrasound query wave, or mean grayscale value (MGV) associated with the ultrasound data of the smart hydrogel microresonator structure due to the change in resonance frequency. Such change can be correlated to concentration of the analyte.

Low-Cost Microfluidic Sensors With Smart Hydrogel Patterned Arrays Using Electronic Resistive Channel Sensing For Readout

View page
US Patent:
20200114353, Apr 16, 2020
Filed:
Oct 14, 2019
Appl. No.:
16/601120
Inventors:
- Salt Lake City UT, US
Navid Farhoudi - Salt Lake City UT, US
Christopher F. Reiche - Salt Lake City UT, US

International Classification:
B01L 3/00
G03F 7/20
G01N 27/12
Abstract:
Microfluidics sensor devices having an array of smart polymer hydrogel features for resistive channel analyte sensing via hydrogel swelling and de-swelling, and methods of manufacturing and using the same. Inexpensive, rapid-responsive, point-of-use sensors for monitoring disease biomarkers or environmental contaminants in, for example, drinking water, employ smart polymer hydrogels as recognition elements that can be tailored to detect almost any target analyte. Fabrication involves mask-templated UV photopolymerization to produce an array of smart hydrogel pillars, with large surface area-to-volume ratios, inside sub-millimeter channels located on microfluidics devices. The pillars swell or shrink upon contact aqueous solutions containing a target analyte, thereby changing the resistance of the microfluidic channel to ionic current flow when a bias voltage is applied to the system. Hence resistance measurements can be used to transduce hydrogel swelling changes into electrical signals. A portable potentiostat can be included to make the system suitable for point of use.

H01F 5/00
Abstract:
Systems, methods, and sensor devices for identifying one or more changes in a stimulus-responsive hydrogel include a sensor device having (i) a sensing structure and (ii) a stimulus-responsive hydrogel associated with a first side of the sensing structure. The sensing structure includes a flexible thin film polymer and an electric sensing element capable of electric impedance change, and the hydrogel is configured to dimensionally change in response to predefined stimuli such that a dimensional change of the hydrogel causes a change in an impedance property of the electric sensing element. Systems including such a sensor device can additionally include a meter in electrical communication with the sensor device to identify changes in the impedance properties of the structure and/or a catheter sheath configured for placement within an in vivo environment and is sized and shaped to receive the sensor device within a lumen thereof.
