Abstract

A method for dispensing liquid for use in biological analysis may comprise positioning liquid to be dispensed via electrowetting. The positioning may comprise aligning the liquid with a plurality of predetermined locations. The method may further comprise dispensing the aligned liquid from the plurality of predetermined locations through a plurality of openings respectively aligned with the predetermined locations. The dispensing may be via electrowetting.

Claims (9)

1. A method for dispensing liquid to a plurality of reservoirs, the method comprising:

positioning, via electrowetting, liquid to be dispensed, the positioning comprising aligning the liquid with a plurality of predetermined locations; and

dispensing, using electrophoresis, the aligned liquid from the plurality of predetermined locations to the plurality of reservoirs through a plurality of openings respectively aligned with the predetermined locations.

2. The method of claim 1 , further comprising dividing the liquid into a plurality of individual portions via electrowetting, wherein the positioning comprises aligning each of the plurality of individual portions with the plurality of predetermined locations.

3. The method of claim 1 , wherein the dispensing the aligned liquid comprises dispensing the aligned liquid through a plurality of openings of a plurality of nozzles.

4. The method of claim 3 , further comprising spotting the liquid to a testing platform via the plurality of nozzles.

5. The method of claim 1 , wherein the dispensing the aligned liquid to a plurality of reservoirs comprises dispensing the aligned liquid to a plurality of reservoirs coated with a hydrophilic material.
