US Patent:

20130126358, May 23, 2013

Filed:

Jan 9, 2013

Appl. No.:

13/737360

Inventors:

TECAN TRADING AG - Mannedorf, CH
Michael Benjamin Franklin - Claremont CA, US
Kailiang Wang - Sunnyvale CA, US

Assignee:

TECAN TRADING AG - Mannedorf

International Classification:

G01N 27/447

US Classification:

204600

Abstract:

A liquid droplet manipulation system has a substrate with at least one electrode array and a central control unit for controlling selection of individual electrodes of the electrode array and for providing the electrodes with individual voltage pulses for manipulating liquid droplets by electrowetting. A working film is placed on top of the electrodes for manipulating samples in liquid droplets with the electrode array. At least one selected individual electrode of the electrode array is configured to be penetrated by light of an optical detection system for the optical inspection or analysis of samples in liquid droplets that are located on the working film. Also disclosed is working film that is to be placed on the electrode array and a cartridge that includes such a working film for manipulating samples in liquid droplets.

Abstract:

Liquid droplet manipulation instrument has electrode array for inducing movement of a droplet by electrowetting, substrate supporting the array and control with electrode selector connected to a voltage control. The selector selects each electrode and provides each with a controlled voltage. The control includes central processing unit for providing the selected electrode with an individual voltage pulse which is a drive voltage or a ground voltage or a stop voltage. The control defines a path for movement of a liquid portion of a larger volume that covers more than one electrode by the simultaneous selection of a group of two or more subsequent drive electrodes and to provide each selected drive electrode with a drive voltage pulse along the path. The control simultaneously provides a group of two or more electrodes adjacent to or identical with the pulsed drive electrodes, with a ground or stop voltage pulse.
