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.

Disclosed herein is a cell culture device and its applications of creating gradient of chemicals or gradient of cells to mimic the in vivo physiological conditions of homeostasis.

Gradient-on-a-chip

A wearable paper-based platform with simultaneous passive and active feedback for monitoring perspiration is provided. The sensor platform comprises two modules: a disposable wicking-based sweat collection patch with discrete colorimetric feedback, and a reusable electronic detachable module for active feedback. The disposable patch comprises a hygroscopic wicking material laminated between two polymeric films. The wicking material is patterned with a radial finger design that offers discretized visual readout of the sensor. The active module attaches to the film and alerts the user when the film collects a pre-determined volume of sweat. The multi-feedback system allows high-performance athletes who value objective quantification of perspiration to better assess their sweat loss during physical activities.

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.
