Abstract
A microfluidic device for manipulating microdroplets is provided. It includes (a) a microfluidic space defined at least in part by juxtaposition of opposed containing walls and (b) disposed on or within at least one of the containing walls optoelectrowetting electrode locations arranged in a pathway characterised in that in at least one direction substantially parallel to that of the pathway a region of the microfluidic space continuously varies or may be caused to continuously vary in depth; for example by tapering or cantilevering a resilient part of one of the walls. The device and its associated method of use are suitable components for nucleic acid sequencers and biomedical analytical devices.
