In this latter case the resulting product, hydrogen peroxide, affects polypyrrole structure 87. However, in both cases low catalytic currents were observed for the acrylic hydrogel. Analyte signal processing device and methods 2009-09-29 2017-09-05 Abbott Diabetes Care Inc. In this way, catalytic curves were studied with two enantiomeric forms of a ferrocene derivative giving equal catalytic response. Google has not performed a legal analysis and makes no representation or warranty as to the accuracy of the list. Metabolic reactions are represented as biotransformation rules. System and method for analyte measurement employing maximum dosing time delay 2003-06-13 2009-10-20 Pelikan Technologies, Inc.
A content in a graphite paste of less then 0. Since food products and their raw materials are complex mixtures of chemical compounds, highly specific, cost-effective, and reliable methods are increasingly needed. The pores of the porous electrode thus prepared were impregnated with a quinone-containing material to form a storage layer the carrier of the present invention. Blood glucose tracking apparatus and methods 2001-04-02 2011-07-12 Abbott Diabetes Care Inc. Graphic Designers need to be proficient in all of these applications, plus the widely used applications like Word.
In this study, studies on biosensors used for pesticide analyses were summarized and then researches on acetylcholinesterase inhibition based biosensors developed by using conducting polymers for pesticide analyses were reviewed. The peak was noted at -0. After leaving the electrode to stand overnight, measurement was effected. Analyte monitoring device and methods of use 1998-04-30 2015-06-30 Abbott Diabetes Care Inc. It was found that the anodic current at +0. Analyte monitoring device and methods of use 1998-04-30 2014-07-08 Abbott Diabetes Care Inc.
As a still further alternative, the enzyme may be placed within and bonded to the porous substructure so that the third outer membrane may be eliminated. Transcutaneous analyte sensor 2004-07-13 2013-08-20 Dexcom, Inc. The surface was covered further with a dialysis film 0. The feasibility of designing trienzyme electrodes where the enzymes are immobilized in a redox polymer matrix was reported by Michael et al. Between analyses the biosensor is placed in oxygenated buffer devoid of glucose.
Analyte monitoring device and methods of use 1998-04-30 2012-11-06 Abbott Diabetes Care Inc. Consecutive enzymatic reactions can be applied to amperometric sensor design. Main article: membranes are made from an ion-exchange type of glass or. Analyte sensor 2003-07-25 2017-09-19 Dexcom, Inc. Techniques to improve polyurethane membranes for implantable glucose sensors 2002-05-22 2011-11-01 Dexcom, Inc.
Accordingly, it is an object of the present invention to provide an improved laminated membrane for use in an enzyme electrode. In one embodiment, the electrical conductor is a carbon cloth that permits oxygen or other gas to be introduced to the perfluorosulfonic polymer to promote the enzyme reaction independent of oxygen in the solution being tested. Mass transport limited in vivo analyte sensor 1999-11-04 2003-09-09 Therasense, Inc. The glucose diffuses through the membrane and is converted by the enzyme to gluconic acid, which then diffuse both toward the pH sensitive glass and back into the donor solution. As the porous material, it is preferable to use a porous molding of a conductive or semi-conductive substance, such as sintered material or sponge, which is processed into the desired form. An attractive approach for enzyme immobilization is electrochemical polymerisation.
An improved alternative is the use of an oxidizing species other than oxygen 25,26. Analyte monitoring device and methods of use 1998-04-30 2012-07-24 Abbott Diabetes Care Inc. What is claimed is: 1. This review provides an overview of different electrochemical and surface plasmon immunoassays for insulin. Method and apparatus for lancet actuation 2002-05-02 2008-05-06 Abbott Diabetes Care Inc. Method and apparatus for a point of care device 2003-06-20 2009-10-20 Roche Diagnostics Operations, Inc. As a result of such impregnation, the electron transfer mediator is well supplied in a high concentration to the enzyme-immobilized surface.
Other conducting polymers have been employed for enzyme immobilization such as poly thiophenes 91, poly indoles 92 and poly aniline 93,94. In this case three alternatives emerge: direct communication between electrode and enzyme which implies no redox mediator; soluble redox mediators and immobilised mediators. Such carrier acts as a sort of storage layer for the electron transfer mediator, and its capacity is properly decided according to the term of use and the ease of treatment of the enzyme electrode. Une limite de détection de 10 bactéries a été déterminée dans les échantillons artificiels. The grid electrode having many spaces is a preferable embodiment, because it is possible by employing it to prevent superfluous permeation or elution onto the carrier surface of the electron transfer mediator in the carrier. Electrochemical sensor and method thereof 2000-06-27 2003-07-08 Therasense, Inc. The most characteristic feature of the present invention resides in the point that the carrier for immobilizing enzyme is impregnated with a substance which can be the electron transfer mediator for enzyme reaction.
