Abstract

A device for rapid non-destructive genetic material collection can include a multi-reservoir array ( 202 ) and a movement mechanism. The multi-reservoir array ( 202 ) can include multiple reservoirs ( 204 ). A plurality of the multiple reservoirs ( 204 ) can include an abrasive surface ( 210 ) capable of retaining a source of genetic material in a liquid carrier. The abrasive surface ( 210 ) has a roughness. The movement mechanism can be operable to move the multi-reservoir array ( 202 ) in an oscillating motion sufficient to create relative movement between the abrasive surface ( 210 ) and the source of the genetic material in order to remove a portion of genetic material from the source of the genetic material without destroying the source of the genetic material or the portion of the genetic material that is removed.

Claims (26)

1. A device for rapid non-destructive genetic material collection, comprising:

a multi-reservoir array including multiple reservoirs, wherein a plurality of the multiple reservoirs, include an abrasive surface, capable of retaining a source of genetic material in a liquid carrier wherein the abrasive surface has a roughness; and

a movement mechanism configured to move the multi-reservoir array in an oscillating motion, and thereby configured to create relative movement between the abrasive surface and the source of the genetic material in order to remove a portion of genetic material from the source of the genetic material without destroying the source of the genetic material or the portion of the genetic material that is removed.

2. The device of claim 1 , wherein the multi-reservoir array comprises an open top droplet system wherein the multiple reservoirs are formed having a reservoir bottom, reservoir side wall, and an open top to allow access to the multiple reservoirs.

3. The device of claim 2 , wherein the multi-reservoir array comprises a slide forming the reservoir bottom, a hydrophobic tape with holes that form the reservoir side walls, and the abrasive surface comprises a roughened surface on the slide.

4. The device of claim 2 , wherein the reservoir side wall comprises a molded polydimethylsiloxane (PDMS) and the molded PDMS is adhered to a slide.

5. The device of claim 1 , wherein the multi-reservoir array comprises up to 96 reservoirs and the reservoirs are circular with a diameter ranging from 2 mm to 8 mm in size.

6. The device of claim 1 , wherein the abrasive surface comprises a member selected from the group consisting of a roughened portion of the multiple reservoirs, an abrasive material attached to an interior surface of the multiple reservoirs, and a combination thereof.

7. The device of claim 1 , wherein the abrasive surface is located along a bottom of the multiple reservoirs, a side wall of the multiple reservoirs, or a combination thereof.

8. The device of claim 1 , wherein the roughness (Ra) and a surface waviness (Wa) ranges from 1 μm to 100 μm.

9. The device of claim 1 , wherein the movement mechanism comprises a member selected from the group consisting of a shaker plate, an orbital shaker, a linear shaker, a rocking shaker, a gyratory rocker, a micro-plate mixer, a vibration motor, a coin vibration motor, a reciprocating rack, a sonic generator, an ultrasound transducer, a pump, and a combination thereof.

10. The device of claim 1 , wherein the movement mechanism is located along a bottom surface of the multi-reservoir array.

11. The device of claim 1 , wherein the movement mechanism is located adjacent a lateral edge of the multi-reservoir array.

12. A method of rapid non-destructive genetic material collection; comprising:

retaining an living source of genetic material within multiple reservoirs having an abrasive surface therein;

moving the abrasive surface relative to the living source of the genetic material in a manner that removes genetic material from the source of the genetic material without destroying the genetic material and the living source of the genetic material to form a recovered genetic material; and

collecting the recovered genetic material.

13. The method of claim 12 , wherein the living source of genetic material comprises a 24-96 hour post fertilization embryo.

14. The method of claim 12 , wherein a species of the living source of genetic material is Danio rerio, drosophila , nematode, C. elegans , or xenopus.

15. The method of claim 12 , wherein retaining the living source of genetic material within the multiple reservoirs comprises loading the reservoirs with a 10 μL to 20 μL buffer solution containing the living source of the genetic material.

16. The method of claim 12 , wherein moving the abrasive surface relative to the living source comprises oscillating the multiple reservoirs in a 1 mm to 5 mm diameter circular planar motion at 50 rotations per second (Hz) to 250 Hz.

17. The method of claim 12 , wherein moving the abrasive surface relative to the living source comprises placing the multiple reservoirs on a 1 volt to 3 volt coin vibration motor and operating the coin vibration motor for a period of time ranging from 5 minutes to 15 minutes.

18. The method of claim 12 , wherein the method further comprises amplifying the recovered genetic material using polymerize chain reaction (PCR) to form amplified genetic material.

19. The method of claim 18 , wherein the method further comprises analyzing the amplified genetic material using a technique selected from the group consisting of gel electrophoresis, high resolution melt analysis, and a combination thereof.

20. The method of claim 11 , wherein a process time to collect the genetic material from 48 or fewer of the living source of the genetic material is thirty minutes or less with a survival rate of the living source of genetic material of greater than 90%.

21. The method of claim 11 , wherein a process time to collect the genetic material from 24 or fewer of the living source of the genetic material is twenty minutes or less with a survival rate of the living source of genetic material of greater than 90%.
