Abstract

The disclosed subject matter provides a system and methods for automated imaging and manipulation of small animals. In exemplary embodiments, the disclosed subject matter provides a motorized picking assembly, that is coupled to a processor and adapted to remove selected small animals from a source plate and transfer them to a destination plate. The disclosed subject matter provides methods, which include identifying at least one parameter for the small organisms, selecting organisms based on the parameter and transferring selected organisms from the source plate to the destination plate. In certain embodiments, the disclosed subject matter provides a handheld self-sterilizing loop tool for the manual manipulation of small organisms.

First claim

The invention claimed is:

1. A handheld tool for manual manipulation of small animals, comprising a handle and a tip assembly, wherein the tip assembly comprises contact pins, contact sockets, and a wire loop, and wherein the contact pins connect to the contact sockets within the tip assembly.

2. The handheld tool of claim 1 , wherein the handle comprises a battery.

3. The handheld tool of claim 2 , wherein the wire loop is configured to be connected to the battery through the contact pins, and the battery is configured to generate an electrical current that passes through the wire loop and the contact pins, heating the wire loop for sterilization.

4. A method for automated imaging and manipulation of small animals, comprising: identifying at least one parameter for a plurality of small animals; selecting one or more small animals based on the at least one parameter; removing the one or more selected small animals from at least one source plate using a handheld self-sterilizing loop tool comprising a handle, a tip assembly, a wire loop, contact pins, and contact sockets, and wherein the contact pins connect to the contact sockets within the handheld self-sterilizing loon tool.

5. The method of claim 4 , wherein the at least one parameter is an approximate size and shape for at least a portion of the plurality of small animals.

6. The method of claim 4 , wherein the at least one parameter is a fluorescence signal for at least a portion of the plurality of small animals.

7. The method of claim 4 , further comprising taking a lid off the at least one source plate before removing the one or more selected small animals from the at least one source plate.

8. The method of claim 7 , further comprising replacing the lid on the at least one source plate after removing the one or more selected small animals from the at least one source plate.

9. The method of claim 5 , wherein the approximate size and shape for the at least a portion of the plurality of small animals is identified with a camera.

10. The method of claim 9 , further comprising aligning an illuminator with a position of the camera such that the illuminator illuminates upwards into the camera.

11. The method of claim 4 , further comprising sterilizing the wire loop by generating a current that passes through the wire loop and contact pins within the handheld self-sterilizing loop tool.

12. The method of claim 4 , wherein a battery in the handle is configured to generate a current heating the wire loop to a temperature in excess of 1000 degrees Fahrenheit.
