    摘要: A magnetic connector assembly for microfluidic devices comprises a first magnetic connector with at least one orifice extending therethrough and a second magnetic connector. The first and second connectors are configured to magnetically attract each other. In one aspect, the first magnetic connector is configured to sealingly engage a surface of a microfluidic chip with the second magnetic connector disposed on an opposite side of the microfluidic chip. The first magnetic connector is configured to seal with the microfluidic chip about a channel opening in the microfluidic chip and provide flow communication between the channel opening and the orifice in the first magnetic connector. In at least one other aspect, the first magnetic connector and second magnetic connector each have at least one orifice and are configured to change a flow communication therebetween upon a rotation of the first or second magnetic connector with respect to the other magnetic connector.

    摘要: A microfluidic device is described, capable of generating multiple spatial chemical gradients simultaneously inside a microfluidic chamber. The chemical gradients are generated by diffusion, without convection, and can either be maintained constant over long time periods, or modified dynamically. A representative device is described with a circular chamber in which diffusion occurs, with three access ports for the delivery and removal of solutes. A gradient typically forms in minutes, and can be maintained constant indefinitely. Gradients overlapping with different spatial location, and a controlled rotation of a gradient formed by diffusion are demonstrated. The device can also be used to evaluate chemotactic responses of bacteria or other microorganisms in the absence of convective flow.

    摘要: A method and microfluidic platform is provided for providing a closed loop, microfluidic circulatory system having the steady flow of fluid therethrough. A first flow path is filled with a first fluid. The first flow path has an inlet and an outlet. A passageway extending through a first tube is filled with a second fluid. The passageway has first and second ends. The first end of the passageway is interconnected to the inlet of the first flow path and the second end of the passageway is interconnected to the outlet of the first flow path. A pump pumps the first and second fluids in steady flow through the first flow path and the passageway.
