Centrifugal lithography (CL) enables fabrication of microstructures via self-shaping of viscous polymer drops during a centrifugation. Hyungil Jung and co-workers fabricate dissolving microneedles (DMNs) composed of polymer matrix and biopharmaceutics by CL under controlled environments to preserve their activity in article number 1700326. DMNs are penetrated and implanted into skin and delivered their ingredients through the skin to induce biopharmaceutical effects with minimal damage.
