Abstract

Disclosed is an apparatus and associated method for tagging insects and arthropods. According to an exemplary embodiment of this disclosure, an electrosprayer is provided including a nozzle cartridge, a spray chamber removably attached to the nozzle cartridge and a power supply operatively connected to the nozzle cartridge and a grounding plate within the spray chamber to electrically charge droplets expelled from the nozzle which coat one or more insects contained in the spray chamber.

First claim

What is claimed is:

1. A method for tagging a subject, comprising:
adding a tagging agent into a reservoir of a nozzle cartridge, wherein the nozzle cartridge also comprises a first electrical connector and at least one nozzle, wherein the at least one nozzle is operatively associated with the reservoir and inserted through at least one hole in a bottom end of the nozzle cartridge, wherein the at least one nozzle does not protrude below the bottom end of the nozzle cartridge, and wherein the first electrical connector is operatively connected to one of the reservoir and the at least one nozzle;
adding the subject into a spray chamber, wherein the spray chamber comprises a chamber body, a spray chamber bottom plate comprising a rounding plate and a second electrical connector operatively connected to the grounding plate, wherein the chamber body is adapted to form a confinement space for tagging a subject provided therein, and wherein the grounding plate is adapted to substantially cover a bottom portion of the spray chamber opposite a top portion of the spray chamber;
inserting the nozzle cartridge into a top section of a head assembly, wherein the head assembly is adapted to be removably attached to a top portion of the spray chamber, wherein the nozzle cartridge is removably inserted into the top section of the head assembly, and wherein the head assembly is adapted to direct the at least one nozzle into the top portion of the spray chamber;
connecting a high voltage source to provide a voltage and current across the first electrical connector and the second electrical connector, thereby charging droplets of the tagging agent within the reservoir; and
spraying the subject with charged droplets of the tagging agent expelled from that at least one nozzle and directed to the grounding plate.

2. The method of claim 1 , wherein the nozzle cartridge has a top end comprising a syringe connector.

3. The method of claim 1 , additionally comprising a laser configured to light an area below the nozzle cartridge within the spray chamber wherein the spray chamber includes two diametrically opposing openings to allow the laser beam to propagate through the spray chamber.

4. The method of claim 3 , wherein the spray chamber includes a third opening to view the laser light.

5. The method of claim 1 , wherein the high voltage source is configured to apply ten kilovolts or less of voltage.

6. The method of claim 1 , wherein the tagging agent comprises a fluorescent dye, quantum dots, molecular beacons, aptamers, proteins, aqueously suspended metallic particles, or any combination thereof.

7. The method of claim 1 , wherein the subject is an arthropod.

8. The method of claim 1 , wherein at least a portion of the subject is coated with the tagging agent.
