Abstract: Provided herein are microneedle particles, compositions that include microneedle particles, methods of treating skin, and methods of delivering a substance of interest. The microneedle particles may include one or more microneedles, and the microneedle particles may be configured to prevent the entire microneedle particle from penetrating the biological tissue. The microneedle particles may be dispersed in a liquid medium to form a composition. A biological tissue may be contacted with the microneedle particles to pre-treat the biological tissue, and a substance of interest may be applied to the pre-treated biological tissue.

Abstract: Components with relatively high loading of active pharmaceutical ingredients (e.g., drugs), are generally provided. In some embodiments, the component (e.g., a tissue interfacing component) comprises a solid therapeutic agent (e.g., a solid API) and a supporting material (e.g., a binder such as a polymer) such that the solid therapeutic agent is present in the component in an amount of greater than or equal to 10 wt % versus the total weight of the tissue interfacing component. Such tissue-interfacing components may be useful for delivery of API doses e.g., to a subject. Advantageously, in some embodiments, the reduction of volume required to deliver the required API dose as compared to a liquid formulation permits the creation of solid needle delivery systems for a wide variety of drugs in a variety of places/tissues (e.g., tongue, GI mucosal tissue, skin) and/or reduces and/or eliminates the application of an external force in order to inject a drug solution through the small opening in the needle. In some cases, a physiologically relevant dose may be present in a single tissue interfacing component (e.g., having a relatively high API loading).

Abstract: A microsensor and method of manufacture for a microsensor, comprising an array of filaments, wherein each filament of the array of filaments comprises a substrate and a conductive layer coupled to the substrate and configured to facilitate analyte detection. Each filament of the array of filaments can further comprise an insulating layer configured to isolate regions defined by the conductive layer for analyte detection, a sensing layer coupled to the conductive layer, configured to enable transduction of an ionic concentration to an electronic voltage, and a selective coating coupled to the sensing layer, configured to facilitate detection of specific target analytes/ions. The microsensor facilitates detection of at least one analyte present in a body fluid of a user interfacing with the microsensor.
