Abstract: Systems, methods, and apparatuses of controlling fluid flow are disclosed. An apparatus includes a first microplate having a first open portion and defining one or more first wells therein, a second microplate having a second open portion and defining one or more second wells therein, and a pneumatic lid constructed of styrene ethylene butylene styrene (SEBS). The pneumatic lid extends over the first open portion and the second open portion and includes one or more microfluidic channels that fluidly couple the one or more first wells to the one or more second wells. The pneumatic lid provides an airtight seal over the first microplate and the second microplate.

Abstract: Apparatus and methods to improve the Boyden chamber used in cellular biological measurements, allowing quantitative optical microscopy of biological cells in situ without using fluorescent probes or optical staining. A thin, porous membrane separating top and bottom reservoirs includes an array of precisely positioned micropores pores manufactured using a laser-based photo-machining (ablation) process. The membrane may be composed of polyethylene terephthalate (PET), polycarbonate, polyimide, polyether ether ketone (PEEK), polystyrene, or other appropriate material. The pores formed in the membrane may have diameters in the range of 1 to 15 microns and spaced apart at a distance ranging from 10 to 500 microns. A plurality of upper and lower reservoirs may be provided to form a multi-well plate.

Abstract: Systems, including apparatus and methods, for performing electrophysiological measurements on membranous samples, including living cells, isolated cell fragments (such as organelles), and/or artificial membranes (such as vesicles). The apparatus may include a high-throughput electrophysiological measurement system, and components thereof. This measurement system may include, among others, (1) a fluidics head for transferring samples and/or other compounds to a perforated measurement substrate, (2) a pressure-regulated plenum system for positioning samples on the substrate and subsequently forming a high-resistance electrical seal, (3) an activation system (such as a computer-controlled pulsed UV illumination module) for activating caged compounds, (4) an electronics head for applying and/or measuring voltage and/or current, and/or (5) a computer-controlled analysis system for collecting and/or analyzing data.

Abstract: Standard electrophysiology via the patch clamp technique is a well-developed and powerful tool in both academic and industrial research in the study of ion channels and transporters. Although widely accepted as the gold standard for these types of measurements, the patch clamp technique is considered labor intensive and relatively slow, limited to measuring only one biological sample at a time. This invention describes and demonstrates a device whereby electrophysiological measurements can be made on cells or cell membranes in a manner which allows for multiple measurements to be made in parallel, without direct human intervention, thereby enhancing the cost effectiveness, throughput and general applicability of the technique in fields such as pharmaceutical drug screening.
