NANOFIBER STRUCTURES ON ASPERITIES FOR SEQUESTERING, CARRYING AND TRANSFERRING SUBSTANCES

摘要

A device which comprises a substrate which includes a plurality of asperities, such as microneedles, extending from the surface of the substrate, and an electrospun material in contact with the substrate. The electrospun material may comprise a plurality of nanofibers which carry at least one biologically active agent. Such devices are useful as transdermal delivery devices for delivering pharmaceuticals and other biologically active agents.
