Abstract: A therapeutic delivery system uses an engineered extracellular vesicle-albumin hybrid carrier for curcumin, which is embedded in dissolvable microneedle arrays. The co-encapsulation of curcumin with albumin in extracellular vesicles extends curcumin's stability. The incorporation of therapeutic loaded carrier into microneedle arrays does not alter its cell uptake properties or bioactivity. Moreover, the bioactivity of therapeutic loaded carrier can be preserved for at least one year when encapsulated in microneedle arrays and stored under room temperature storage conditions. The microneedle arrays of the delivery system are fabricated using molding and casting processes. The extracellular vesicle carrier can be loaded using sonication.

Abstract: A system and method used to fabricate an implant from cartilage, where the implant can be used in reconstructive surgery. The system includes a thermoregulation device capable of maintaining a desired temperature range during milling operations. The milling machine is controlled by instructions generated from a digital model of the implant. The digital model can be a stock model or a custom model created from medical scans.

Abstract: A method of immobilizing extracellular vesicles in an extracellular matrix material provides for improved extracellular vesicle retention in vitro and in vivo. Extracellular matrix materials, such as collagen, are functionalized with chemicals that are complimentary to ligands disposed on the surface of the extracellular vesicle. In one example embodiment, collagen is functionalized with dibenzocyclooctyne and the extracellular vesicle is functionalized with an azide tag. The extracellular vesicle is immobilized within the collagen through a click reaction involving the dibenzocyclooctyne and the azide tag.

Abstract: Provided herein are tethered extracellular vesicles and methods of making tethered extracellular vesicles.

Abstract: Provided herein are devices and methods used to produce tattoo biosensors that are based on spatially controlled intracutaneous gene delivery of optical reporters driven by specific transcription factor pathways for a given cytokine or other analyte. The biosensors can be specific to a given analyte, or more generically represent the convergence of several cytokines into commonly shared intracellular transcription factor pathways. These biosensors can be delivered as an array in order to monitor multiple cytokines. Biosensor redeployment can enable chronic monitoring from months to years. The tattooed biosensor array of the present invention includes endogenous reporter cells, naturally tuned to each patient's own biology and can be used to reliably measure the state of a patient in real-time.
