Nanopatterned medical device with enhanced cellular interaction
A medical device for delivering a drug compound through a stratum corneum includes a support having an aperture, an array of microneedles extending outwardly from the support, a plurality of nanostructures associated with each microneedle, and a reservoir wherein the drug compound is retained. At least one microneedle contains a shaft extending from the support. The shaft includes a tip configured to penetrate the stratum corneum. The shaft defines a channel extending from the support to the tip. The channel is in at least partial alignment with the aperture. At least some of the microneedles of the array of microneedles each have a cross-sectional dimension of from about 1 micrometer to about 1 millimeter. At least some of the nanostructures have a cross-sectional dimension less than about 500 nanometers and greater than about 5 nanometers and an aspect ratio of from about 0.2 to about 5.
Method for integrating structures in a support and associated device
The invention relates to a method for integrating structures in a support, which comprises the steps: a) supplying a support comprising a front face and a rear face, and through cavities each delimited by a wall designated through wall; b) inserting into each of the through cavities a structure, provided with a first face and a second face connected by a contour, the first face and the front face being coplanar, the through cavities and/or the structures being laid out to leave a peripheral space; c) filling the peripheral space with a sealing material so as to maintain the structures to the support; The peripheral space has a radial extension length which decreases from the rear face to the front face.
