Abstract:
1. A method of manipulating a liquid droplet comprising: providing a first plate comprising a predetermined pattern of independently addressable first electrodes on a surface of the first plate; providing a second plate comprising a predetermined pattern of a continuous second electrode on a surface of the second plate, the predetermined pattern of the continuous second electrode having a first predetermined pattern of first nanostructures formed therein; assembling the first plate and second plate in a predetermined orientation with respect to one another such that the predetermined pattern of independently addressable first electrodes and the first predetermined pattern of first nanostructures on the second electrode face one another and orientated relative to one another in a predetermined orientation determined in dependence upon the predetermined pattern of independently addressable first electrodes and the first predetermined pattern of first nanostructures on the second electrode; providing a controller for generating a predetermined sequence of electrical signals to a predetermined subset of the predetermined pattern of independently addressable first electrodes in order to displace and position an isolated liquid droplet comprising a first liquid disposed between the first plate and second plate, the displacement and positioning of the isolated liquid droplet being made absent the presence of any other liquid between the first plate and second plate and absent any coating applied to the surface of the independently addressable first electrodes and the surface of the second electrode having the first predetermined pattern of first nanostructures.
