    Abstract: A 3D microelectrode device includes a flexible substrate containing poly-dimethyl siloxane (PDMS). The device may be fabricated in a miniature form factor suitable for attachment to a small organ such as a lateral gastrocnemius muscle of a live rat. In addition to providing a miniaturized, conformable attachment, the device provides an anchoring action via one or more microelectrodes, each having an insertable tip particularly shaped to provide the anchoring action. Furthermore, a base portion of each of the microelectrodes is embedded inside conductive poly-dimethyl siloxane (cPDMS). The cPDMS is contained in a pad that is coupled to a conductive track embedded in the flexible substrate. Embedding of the base portion inside the cPDMS material not only allows the microelectrode to bend in various directions, but also provides good electrical conductivity while eliminating the need for attachment processes using solder or epoxy adhesives.

    Abstract: Electrophysiology culture plates are provided and are formed from a transparent micro-electrode array (MEA) plate. The MEA plate comprises a substrate, a first layer and a first insulating layer. The substrate has a plurality of vias extending from an upper to a lower surface, each via being in electrical contact with each of a plurality of contact pads disposed on the lower surface. The first layer is disposed on the upper surface of the substrate and has a plurality of MEA arrays in in electrical communication with at least a first routing layer. Each MEA array comprises a plurality of reference electrodes and a plurality of microelectrodes and the first routing layer is in electrical communication with a select number of the plurality of vias. A first insulating layer is disposed on the first layer. The MEA plate is joined to a biologic culture plate having a plurality of culture wells such that each culture well defines an interior cavity having a bottom surface that is at least partially transparent and in positioned in registration with a select optical port. The MEA plate is coupled to the biologic culture well plate such that each MEA array is operatively coupled to one culture well wherein each microelectrode and each reference electrode are in electrical communication with the interior cavity through the bottom surface of the culture well.

    Abstract: Devices, systems, and methods for facilitating placement of cells and materials in culture plates configured for high-throughput applications are provided. A culture system is provided with a culture plate having a lid for guiding placement of cells and materials in each individual culture well of a culture plate. The lid may provide for coupling to an electrophysiology culture plate comprising a biosensor plate and a biologic culture plate, where the biosensor plate underlies and is coupled to the culture well plate such that each biosensor is operatively coupled to one culture well of the plurality of culture wells. A containment device that physically influences the positioning of fluid received in the culture plate is also provided herein.
