Abstract

Devices, systems, and methods for facilitating placement of cells and materials in culture plates configured for high-throughput applications are provided. A culture system is provided with a culture plate having a lid for guiding placement of cells and materials in each individual culture well of a culture plate. The lid may provide for coupling to an electrophysiology culture plate comprising a biosensor plate and a biologic culture plate, where the biosensor plate underlies and is coupled to the culture well plate such that each biosensor is operatively coupled to one culture well of the plurality of culture wells. A containment device that physically influences the positioning of fluid received in the culture plate is also provided herein.

Claims (27)

1. A culture plate comprising a plurality of wells for receiving fluid, wherein at least one of the wells comprises:

a biosensor plate, wherein the biosensor plate defines a surface;

a plurality of biosensors;

at least one reference sensor;

at least one containment device; and

an insulating material, wherein the at least one containment device is located such that it physically influences the positioning of the received fluid, wherein the plurality of biosensors, the at least one reference sensor, and the at least one containment device are formed on the surface of the biosensor plate, wherein the insulating material is layered on at least a portion of the surface of the biosensor plate, wherein the insulating material and the plurality of biosensors create a varied topography on the surface of the biosensor plate, and wherein the at least one containment device is configured to concentrate the received fluid to the plurality of biosensors.

2. The culture plate of claim 1 , wherein the at least one containment device is a levee.

3. The culture plate of claim 1 , wherein the at least one containment device is electrically inactive.

4. The culture plate of claim 1 , wherein the at least one containment device is electrically active.

5. The culture plate of claim 1 , wherein the at least one containment device is located between at least one biosensor and the at least one reference sensor.

6. The culture plate of claim 1 , wherein the insulating material is located between at least one biosensor and the at least one reference sensor.

7. The culture plate of claim 1 , wherein the insulating material is located between at least one biosensor and the at least one containment device.

8. The culture plate of claim 1 , wherein the insulating material is located between the at least one reference sensor and the at least one containment device.

9. The culture plate of claim 1 , wherein the at least one containment device is metal.

10. The culture plate of claim 1 , wherein the at least one of the wells comprises a bottom surface,

wherein a portion of the insulating material slopes upward from the bottom surface of the well.

11. The culture plate of claim 1 , further comprising a hydrophobic insulating material adjacent the at least one containment device.

12. The culture plate of claim 1 , wherein the plurality of biosensors, the at least one reference sensor, and the at least one containment device are exposed through the insulating material.

13. The culture plate of claim 1 , wherein each of the plurality of biosensors is configured to record electrical activity from one or more cells and electrically stimulate the one or more cells.

14. A system for targeted placement of materials via a pipette, comprising:

the culture plate of claim 1 ; and

a lid shaped to removably couple to the culture plate, wherein the lid comprises a plurality of extrusions, wherein at least one of the extrusions extends into the at least one of the wells of the culture plate, and wherein the at least one of the extrusions is shaped to accept the pipette and direct contents of the pipette into the at least one of the wells.

15. The system of claim 14 , wherein at least one of the extrusions comprises a collar configured to prevent a portion of the pipette from extending beyond the collar.

16. The system of claim 15 , wherein the collar is configured to prevent a pipette tip from protruding more than a predetermined amount beyond a distal end of the at least one of the extrusions during placement of materials via the pipette.

17. The system of claim 15 , wherein the collar is configured to maintain a predetermined distance between a pipette tip and the plurality of biosensors during placement of materials via the pipette.

18. The system of claim 14 , wherein at least one of the extrusions is one of a frustoconical, cylindrical, and pyramidal shape.

19. The system of claim 14 , wherein the lid comprises a friction-fit feature, the friction-fit feature configured to flex when in contact with the culture plate and removably secure the lid to the culture plate.
