Abstract

Provided herein are a miniature devices, systems and methods for the treatment and manipulation of small model organisms to perform high-throughput screens of small molecules, chemical compounds, bioreactive agents and/or environmental conditions. Disclosed is an apparatus for housing a small model organism in array format the includes an array of chambers joined by a solid support, wherein the bottom of each chamber has a round bottom well, wherein the round bottom of the round bottom well comprises one or more holes that are: (a) of sufficiently large size to be permeable to liquid and (b) of sufficiently small size to prevent exit of the small model organism.

First claim

1 . An apparatus for housing a small model organism in array format comprising:
an array of chambers joined by a solid support, wherein a bottom section of each chamber includes a round bottom well that has one or more holes extending therethrough that are: (a) of sufficiently large size to be permeable to liquid and (b) of sufficiently small size to prevent exit of the small model organism.

2 . The apparatus of claim 1 , further comprising a small model organism in at least one chamber of the array of chambers.

3 . The apparatus as recited in claim 1 , wherein the array comprises 96 chambers in an 8 row by 12 column format.

4 . The apparatus as recited in claim 1 , wherein the solid support is a plastic.

5 . The apparatus as recited in claim 4 , wherein the solid support is selected from the group consisting of a UV cure resin, a polystyrene or polypropylene and a coating of the substrate.

6 . The apparatus of claim 2 , wherein the small model organism is selected from the group consisting of Drosophila melanogaster, Daphnia, Hyalella, C. elegans and zebrafish.

7 . The apparatus as recited in claim 1 , wherein the solid support further comprises at least 3 alignment holes.

8 . The apparatus as recited in claim 1 , wherein the one or more holes formed in the round bottom are approximately 350 microns in size.

9 . The apparatus as recited in claim 1 , further comprising an adapter plate that allows for the interconnection of the array of chambers to a receiver plate, wherein the receiver plate comprises an array of circular deep wells.

10 . The apparatus of claim 9 , wherein the adapter plate comprises an array of square-to-round well adaptors.

11 . The apparatus of claim 1 , wherein a top of the array of chambers is covered by a removable layer that is impermeable to the small model organism.

12 . A kit comprising a feeder plate for housing a small model organism in array format, a receiver plate, and instructions for its use, wherein the feeder plate comprises:
an array of chambers joined by a solid support, wherein the bottom of each chamber includes a round bottom well that has one or more holes that are: (a) of sufficiently large size to be permeable to liquid and (b) of sufficiently small size to prevent exit of the small model organism, and the receiver plate comprises an array of circular deep wells and wherein the receiver plate interfaces with the feeder plate directly or via an adapter plate.

13 . The kit of claim 12 , wherein the array comprises 96 chambers in an 8 row by 12 column format.

14 . The kit of claim 12 , wherein the solid support is a plastic.

15 . The kit as recited in claim 14 , wherein the solid support is selected from the group consisting of a UV cure resin, a polystyrene or polypropylene and a coating of the substrate.

16 . The kit as recited in claim 12 , wherein the solid support for the array of chambers further comprises at least 3 alignment holes.

17 . The kit as recited in claim 12 , wherein the one or more holes of the round bottom are approximately 350 microns in size.

18 . The kit as recited in claim 12 , further comprising an adapter plate that allows for the interconnection of the array of chambers to the receiver plate, wherein the receiver plate comprises an array of circular deep wells.

19 . A method for contacting a small model organism with a test compound, the method comprising introducing the test compound to a 96 well plate and contacting the 96 well plate including the test compound with an apparatus of claim 1 , thereby contacting a small model organism with the test compound.
