    摘要： Remotely controlled platforms for experimentation provide for centralized placement of costly and space consuming experimentation equipment. Additionally, remotely controlled platforms take advantage of economies of scale to make the centralized experimentation platforms more available for students and researchers of institutions that cannot afford to have institutional ownership of the experimentation platforms.

    摘要： A printhead device for transferring liquid droplets from a nozzle includes a liquid source coupled to a nozzle via a microchannel. The nozzle is formed from an orifice having an inner circumferential surface, wherein at least a portion of the inner circumferential surface is serrated. Liquid droplets are transported from the source to the nozzle using a liquid droplet driver (e.g., employing a plurality of driving electrodes). Transfer of droplets to another surface can be accomplished by contacting a bulging droplet in the nozzle with a printing surface. The surface and/or nozzle are then moved relative to one another to effectuate complete transfer of the liquid drop from the nozzle.

    摘要： A refill droplet facilitates the extraction of a droplet laterally from a channel in a microfluidic apparatus. Such extraction allows a discrete band of separated particles or solute molecules to be excised from a fluid stream and processed and analyzed separately. An extraction point is located along the length of the channel and includes an EWOD surface or similar microfluidic technology to extract a droplet. An opening in the channel opposite the extraction means is equipped with microfluidic technology to transport a refill droplet to the opening. The refill droplet is moved into the channel or column to occupy the area previously occupied by the extracted droplet. This prevents distortion or mixing of the bands of particles or molecules within the channel and prevents the draining of any portion of the fluidic system.
