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. A method of making an integrated device comprising:

applying a chemiluminescent material to a support substrate comprising a light detector;

applying a biopolymer to the support substrate;

wherein the biopolymer is configured to activate the chemiluminescent material and the light detector is configured to detect an activity of the chemiluminescent material, and wherein the chemiluminescent material is applied directly on the light detector.

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

3. The method of claim 1, wherein the support substrate comprises glass, nickel, magnetic metal, gold, silicon, nitrocellulose, or polyvinylidene difluoride (PVDF).

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

5. The method of claim 4, wherein the conjugate enzyme is horseradish peroxidase.

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

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

8. The method of claim 1, wherein the chemiluminescent material comprises a cyclic diacylhydrazides.

9. The method 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-trichlorophenoyxl)oxalate, 9,10-Bis(phenylethynyl)anthracene, 5,12-Bis(phenylethynyl)naphthacene, 2-Chloro-9,10-bis(phenylethynyl)anthracene, 1,s-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.

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

11. A method of making an integrated device comprising:

applying a chemiluminescent material to a support substrate comprising a light detector;

applying a biopolymer to the support substrate;

wherein the biopolymer is configured to activate the chemiluminescent material and the light detector is configured to detect an activity of the chemiluminescent material, and wherein the chemiluminescent material is applied directly on the light detector;

wherein an activity of the biopolymer can activate the chemiluminescent material and activity of the chemiluminescent material can be detected by the light detector, wherein a layer of chemiluminescent material is applied directly on the light detector of the support substrate.
