Abstract

The invention described herein provides methods for the detection of soluble antigens. In particular, the methods provide for the detection of soluble proteins and chemicals. In addition, the invention provides methods of detecting a nucleic acid sequence in a sample. Also described is an emittor cell comprising an Fc receptor and an emittor molecule for the detection of a target particle in a sample wherein the target particle to be detected is bound by one or more antibodies. Also provided is an optoelectronic sensor device for detecting a target particle in a plurality of samples.

First claim

What is claimed is:

1. An automated optoelectronic sensor device for detecting a target particle in an air sample using a photon detector comprising:
a) a radial disc comprising a plurality of tubes and valves;
b) an aerosol collection assembly coupled to the radial disc, wherein said aerosol collection assembly localizes particles from the air into said tubes by dry impaction;
c) a manifold assembly, wherein said manifold assembly actuates valves in the radial disc to deliver emittor cells to said tubes wherein said emittor cells comprise a receptor and an emittor molecule, wherein binding of the receptor to an antigen results in an increase in intracellular calcium, and said emittor molecule emits a photon in response to the increase in intracellular calcium, wherein upon rotation of the radial disc the emittor cells are localized in said tubes.

2. The automated optoelectronic sensor device of claim 1 , wherein the emittor molecule is a calcium-sensitive luminescent molecule or a calcium-sensitive fluorescent molecule.

3. The automated optoelectronic sensor device of claim 2 , wherein the emittor molecule is selected from the group consisting of aequorin, obelin, thalassicolin, mitrocomin, clytin, mnemiopsin, berovin, Indo-1, Fura-2, Quin-2, Fluo-3, Rhod-2, calcium green, BAPTA, a cameleon and combinations thereof.

4. The automated optoelectronic sensor device of claim 1 , wherein the emittor cell is a cell selected from the group consisting of a prokaryotic cell, a eukaryotic cell and a non-living cell.

5. The automated optoelectronic sensor device of claim 4 , wherein the emittor cell is selected from the group consisting of a B-cell, a T-cell, a macrophage cell, a mast cell and a fibroblast.
