Abstract: Embodiments of the invention provide constellations of elements useful in glucose sensors as well as methods for making and using such glucose sensors. In typical embodiments of the invention, the sensor is a glucose sensor for diabetics that comprises an analyte sensing membrane formed from a layered stack of material that includes a cellobiose dehydrogenase enzyme composition disposed over an electrode that is further coated with an analyte modulating layer formed from a cellulose acetate composition.

Abstract: Embodiments of the invention provide compositions useful in implantable devices such as analyte sensors as well as methods for making and using such compositions and devices. In typical embodiments of the invention, the device is a glucose sensor comprising a polymeric composition that includes amounts of one or more immunosuppressant agents so as to provide such membranes with improved material properties such as enhanced biocompatibility.

Abstract: Devices, patch sensors, and methods for detecting a ketone body are disclosed. An exemplary device includes a collection apparatus for collecting a sample amount of interstitial fluid and a ketone body indicator having an initial negative state and having a positive state when at least a threshold value of the ketone body is collected in the sample amount.

Abstract: Described here are patches and methods for measuring glucose in sweat (and tears and the like). In general, the patches comprise an adhesive layer adapted to bond to skin of an individual, a substrate layer disposed over the adhesive layer and comprising a glucose sensing complex including a chromogen that changes color in the presence of certain concentrations of glucose, and a cover. In typical embodiments, the substrate layer has elements formed to direct and accumulate sweat that migrates from the skin of the individual to the glucose sensing complex. Methods of using the invention can comprise cleaning the skin surface, collecting sweat in a patch comprising this microfluidic constellation of elements, and observing concentrations of glucose collected in the sweat, for example either visually, or by using a smartphone or other computer processing device.
