摘要： A microfluidic device is provided for delivering a drug to an individual. The microfluidic device includes a body that defines a reservoir for receiving the drug therein. A valve interconnects the reservoir to an output needle that is insertable into the skin of an individual. A pressure source urges the drug from the reservoir toward the needle. The valve is movable between a closed position preventing the flow of the drug from the reservoir to the output needle and an open position allowing for the flow of the drug from the reservoir to the output needle in response to a predetermined condition in the physiological fluids of the individual.

摘要： One aspect of the invention relates to a microfluidic device which recreates important features of the human microcirculation on a microscope stage. In certain embodiments of the invention, the clinical scenario associated with ‘sickle cell crisis’ whereby blood vessels are occluded in various organs causing pain and tissue damage can be recreated. In certain embodiments, one can use a device of the invention to study the processes that lead to crisis, and screen therapies (such as small molecules) that might be used to prevent crisis. Further, certain embodiments of the invention allow one to study and screen therapies for a range of human blood disorders, such as hereditary spherocytosis, disorders of white blood cells, such as Waldenstrom's macroglobulinemia or leukocytosis, disorders of blood platelets and coagulation, such as hemophilia A and B, activated protein C resistance, and essential thrombocythemia.

摘要： In accordance with the present invention, a microfluidic device and method of using the same is provided for self-regulating the flow of fluid therethrough. The microfluidic device includes a body defining first and second flow channels. The first flow channel has an input for receiving the fluid and an output. The second flow channel has an input for receiving a compensating fluid to modify the value of the property of the fluid and an output communicating with the first flow channel. A polymeric material is disposed in the first flow channel downstream of the output of the second flow channel. The polymeric material has a volume responsive to the value of the property of the fluid. A valve is disposed in the second flow channel and is movable in response to the volume of the material. The valve is movable between the first open position allowing the compensating fluid to flow past the valve into the first flow channel and a second closed position limiting the flow of compensating fluid therepast.

摘要： The present invention is drawn to the generation of micropatterns of biomolecules and cells on standard laboratory materials through selective ablation of a physisorbed biomolecule with oxygen plasma. In certain embodiments, oxygen plasma is able to ablate selectively physisorbed layers of biomolecules (e.g., type-I collagen, fibronectin, laminin, and Matrigel) along complex non-linear paths which are difficult or impossible to pattern using alternative methods. In addition, certain embodiments of the present invention relate to the micropatterning of multiple cell types on curved surfaces, multiwell plates, and flat bottom flasks. The invention also features kits for use with the subject methods.
