    摘要: The invention provides droplet actuators with droplet operations surfaces for manipulating droplets, e.g., by conducting droplet operations. The droplet operations surfaces are typically exposed to a droplet operations gap. One or more regions of a droplet operation surface may include patterned topographic features. The invention also provides a droplet actuator in which one or both gap-facing droplet operations surfaces is formed using a removable film. The removable film may, in various embodiments, also include other components ordinarily associated with the droplet actuator substrate, such as the dielectric layer and the electrodes. Further, the invention provides droplet actuator devices and methods for coupling and/or sealing substrates of a droplet actuator, such as techniques for self-aligning assembly of droplet actuator substrates. The invention provides droplet actuators and methods of disassembling the droplet actuator in order to provide access for cleaning and/or recycling of droplet actuator surfaces.
