Assignee: SHARP LIFE SCIENCE (EU) LIMITED
Field: Measurement (Instruments)
Classification: CPC B  G | IPC B  G

Claim 6:
7. A non-transitory computer-readable medium storing program code which is executed by a processing device for controlling actuation voltages applied to array elements of an element array of an electro-wetting on dielectric (EWOD) device comprising an element array configured to receive liquid droplets, the element array comprising a plurality of individual array elements and wherein one of said liquid droplets comprises a fluid reservoir containing particles that is inputted into the EWOD device;
the program code being executable by the processing device to perform the steps of:
performing an electrowetting operation to dispense a plurality of dispensed droplets from the fluid reservoir, the dispensed droplets having a Poisson distribution of droplets containing a desired number of particles;
interrogating each dispensed droplet with a detector and determining whether each dispensed droplet has the desired number of particles;
selecting dispensed droplets that contain the desired number of particles and performing an electrowetting operation to move the selected dispensed droplets to a reaction area on the EWOD device, the selected dispensed droplets having a non-Poisson distribution of droplets containing the desired number of particles; and
rejecting dispensed droplets that do not contain the desired number of particles and performing an electrowetting operation to move the rejected dispensed droplets to a holding area on the EWOD device that is different and spaced apart from the reaction area.
