Abstract

An adhesive composition for use in devices and methods for measuring a presence or a concentration of a particular component, such as an antigen, in a sample, such as blood, are provided. In one exemplary embodiment of an adhesive composition, the composition includes an adhesive, water, a poloxamer, and an anticoagulant. The adhesive can include particular properties, such as being hydrophilic, pressure-sensitive, heat-activated, and/or water soluble. The adhesive is particularly useful because it can help improve the flow of sample a device. For example, when the device is an immunosensor, the adhesive can help prevent the blood from clotting in chambers of the immunosensor. This results in a more efficient and accurate determination of the concentration of the sample. Methods of making the composition and device in which the composition can be used are provided, as are methods of using the same.

Claims (15)

1 . An adhesive composition for use in an immunosensor, comprising:

an adhesive;

water;

a poloxamer; and

an anticoagulant.

2 . The adhesive composition of claim 1 , wherein the anticoagulant is selected from the group consisting of: heparin, citrate, ethylenediaminetetraacetic acid, and oxalate.

3 . The adhesive composition of claim 1 , wherein the poloxamer comprises units derived from ethylene oxide and propylene oxide.

4 . The adhesive composition of claim 3 , wherein ethylene oxide and propylene oxide serve as the monomers in block copolymers.

5 . The adhesive composition of claim 1 , wherein the adhesive is pressure-sensitive.

6 . The adhesive composition of claim 1 , wherein the adhesive is heat-activated.

7 . The adhesive composition of claim 1 , wherein the adhesive is water soluble.

8 . The adhesive composition of claim 1 , wherein the adhesive is a sulfopolyester.

9 . The adhesive composition of claim 1 , wherein a concentration of the poloxamer with respect to the adhesive is approximately in the range of about 0.05 to about 0.5 percent.

10 . The adhesive composition of claim 2 , wherein a concentration of the heparin with respect to the adhesive is approximately in the range of about 0.1 to about 10 milligrams per milliliter.

11 . The adhesive composition of claim 1 , wherein the adhesive and the water are combined to form a mixture prior to being included with the poloxamer and the anticoagulant.
