Abstract: A fluorescent oxygen sensing ink includes at least one organic solvent, at least one polymer binder disposed in the organic solvent, and an oxygen-sensitive fluorescent dye disposed in the organic solvent. The oxygen-sensitive fluorescent dye and the at least one polymer can interact to form a moisture-resistant film. The fluorescent oxygen sensing ink can be incorporated into an oxygen sensing wound dressing.

Abstract: A micropump device. The micropump device includes a first layer forming a first chamber configured to store a working material, a second chamber defined by a deflectable membrane in fluid communication with the first chamber and configured to deflect in response to a pressure increase in the first chamber in response to a volume increase in the first chamber, the second chamber configured to store a drug compound to be delivered to a subject's vascular system, and at least one needle in fluid communication with the second chamber and configured to penetrate a subject's skin to pump the drug compound in response to the deflection of the deflectable membrane.

Abstract: A platform for oxygen generation and delivery is disclosed. The platform includes a hydrophobic substrate with at least one hydrophilic region permeable to gas flow formed thereon having an oxygen generating compound embedded in the at least one hydrophilic region. The platform further includes a microfluidic network with an inlet and an outlet bonded to the hydrophobic substrate with at least one fluid exchange region fluidly coupled to the inlet and the outlet and substantially matching the least one hydrophilic region. The microfluidic network is configured to receive an oxygen rich fluid at the inlet, communicate the oxygen rich fluid to the at least one fluid exchange region to mix with the oxygen generating compound, causing a chemical reaction resulting in formation of oxygen and a chemical byproduct, and communicate the chemical byproduct to the outlet, where the oxygen is permeated out of the at least one hydrophilic region.
