Abstract: Systems and methods for producing and using a body having a first structure defining a first chamber, a second structure defining a second chamber, a membrane located at an interface region between the first chamber and the second chamber to separate the first chamber from the second chamber. The first chamber comprises a first permeable matrix disposed therein and the first permeable matrix comprises at least one or a plurality of lumens each extending therethrough, which is optionally lined with at least one layer of cells. The second chamber can comprise cells cultured therein. The systems and methods described herein can be used for various applications, including, e.g., growth and/or differentiation of primary cells, and/or simulation of a microenvironment in living tissues and/or organs (to model physiology or disease states, and/or to identify therapeutic agents). The systems and methods can also permit co-cultures of two or more different cell types.

Abstract: Compositions, devices and methods are described for preventing, reducing, controlling or delaying adhesion, adsorption, surface-mediated clot formation, or coagulation in a microfluidic device or chip. In one embodiment, blood (or other fluid with blood components) that contains anticoagulant is introduced into a microfluidic device comprising one or more additive channels containing one or more reagents that will re-activate the native coagulation cascade in the blood that makes contact with it “on-chip” before moving into the experimental region of the chip.

Abstract: A method of fabricating electrodes includes forming a first metallic film layer on an upper surface of a first material substrate, and attaching a first polymeric layer to the upper surface of the first material substrate to form a first opened microchannel. The method further includes forming a second metallic film layer on a portion of a lower surface of a second material substrate, and attaching a second polymeric layer to the lower surface of the second material substrate to form a second opened microchannel. The method also includes attaching the first opened microchannel to a bottom side of the membrane and the second opened microchannel to the top side of the membrane. The first metallic film layer and the second metallic film layer each constitute transparent electrodes and are positioned with the membrane therebetween.
