    Abstract: A microfluidic device can include a base an outer surface of which forms one or more enclosures for containing a fluidic medium. The base can include an array of individually controllable transistor structures each of which can comprise both a lateral transistor and a vertical transistor. The transistor structures can be light activated, and the lateral and vertical transistors can thus be photo transistors. Each transistor structure can be activated to create a temporary electrical connection from a region of the outer surface of the base (and thus fluidic medium in the enclosure) to a common electrical conductor. The temporary electrical connection can induce a localized electrokinetic force generally at the region, which can be sufficiently strong to move a nearby micro-object in the enclosure.

    Abstract: A microfluidic device can comprise at least one swept region that is fluidically connected to unswept regions. The fluidic connections between the swept region and the unswept regions can enable diffusion but substantially no flow of media between the swept region and the unswept regions. The capability of biological micro-objects to produce an analyte of interest can be assayed in such a microfluidic device. Biological micro-objects in sample material loaded into a microfluidic device can be selected for particular characteristics and disposed into unswept regions. The sample material can then be flowed out of the swept region and an assay material flowed into the swept region. Flows of medium in the swept region do not substantially affect the biological micro-objects in the unswept regions, but any analyte of interest produced by a biological micro-object can diffuse from an unswept region into the swept region, where the analyte can react with the assay material to produce a localized detectable reaction. Any such detected reactions can be analyzed to determine which, if any, of the biological micro-objects are producers of the analyte of interest.

    Abstract: Some configurations of a microfluidic apparatus can comprise a fluidic circuit of interconnected fluidic structures into which a plurality of different media can be introduced or extracted. A variety of operations can be performed with the different media including isolating with a second medium one or more of the fluidic structures that is filled partially or fully with a first medium. Discrete volumes of a medium can be moved through the isolating second medium to deliver materials or micro-objects to or remove micro-objects or materials from a fluidic structure that is otherwise isolated by the second medium. Some configurations of a microfluidic apparatuses can isolate microfluidic structures in a microfluidic apparatus using flow rates or blocking structures, and some configurations can manage bubbles in fluidic structures.
