Abstract
Electro-osmosis is used to create droplets in order to easily, carefully, and quickly pick-and-place millions of objects (ranging in size from millimeters to nanometers) individually or in parallel. Droplets are formed within channels that are individually controlled in order to achieve a predetermined configuration of the selected objects.
Claims12
An electro-osmosis system, comprising:
- a printed circuit board having an array of fluidic passageways, wherein each fluidic passageway is plated with a conductive material and each fluidic passageway forms part of a channel with an input end and an output end,
- an electro-osmosis pump disposed adjacent a bottom major surface of the printed circuit board and operatively associated with one or more channels at the input end,
- a voltage source to drive the electro-osmosis pump,
- a thermally insulated wire soldered to the output end of the channel and connected to the voltage source to achieve individual control of the channel, and
- a fluid source reservoir from which a droplet is created at the output end of the channel when voltage is applied from the voltage source such that the droplet has a surface tension that creates adhesion in order to pick up an object.
