Abstract

Embodiments of the invention relate to integrated chemiluminescence devices and methods for monitoring molecular binding utilizing these devices and methods. These devices and methods can be used, for example, to identify antigen binding to antibodies. The devices include both a chemiluminescence material and a detector integrated together.

Claims

1. An integrated assay device comprising in order:

a light detector having a light detector substrate;

a layer of chemiluminescent material; and

a biopolymer,

wherein an activity of the biopolymer can activate the chemiluminescent material and the activity of the chemiluminescent material can be detected by the light detector,

wherein the layer of chemiluminescent material is located directly on the light detector substrate.

2. The device of claim 1, wherein the biopolymer is an antibody.

3. The device of claim 1, further comprising a support substrate, wherein the chemiluminescent material, the biopolymer;

and the light detector are on the support substrate.

4. The device of claim 2, wherein the support substrate comprises glass, nickel, magnetic metal, gold, silicon, nitrocellulose, or polyvinylidene difluoride (PVDF).

5. The device of claim 2, wherein the antibody comprises a conjugate enzyme for activating the chemiluminescent material.

6. The device of claim 5, wherein the conjugate enzyme is horseradish peroxidase.

7. The device of claim 2, wherein the antibody is capable of activating the chemiluminescent material upon binding to an antigen.

8. The device of claim 2, wherein the antibody is configured to bind to an antigen of interest.

9. The device of claim 1, wherein the chemiluminescent material comprises a cyclic diacylhydrazides.

10. The device of claim 1, wherein the chemiluminescent material comprises a material selected from the group consisting of luminol, N-(4-Aminobutyl)-N-ethylisoluminol, 4-Aminophthalhydrazide monohydrate, Bis(2-carbopentyloxy-3,5,6-trichlorophenyl)oxalate, 9,10-Bis(phenylethynyl)anthracene, 5,12-Bis(phenylethynyl)naphthacene, 2-Chloro-9,10-bis(phenylethynyl)anthracene, 1,8-Dichloro-9,10-bis(phenylethynyl)anthracene, Lucifer Yellow CH dipotassium salt, Lucifer yellow VS dilithium salt, 85% (dye content), 2,4,5-Triphenylimidazole, 9,10-Diphenylanthracene, Rubrene, and Tetrakis(dimethylamino)ethylene.

11. The device of claim 1, wherein the light detector is a charge-coupled device (CCD) or a complimentary metal-oxide semiconductor (CMOS).
