Rolling Ultrasharp Microneedle Spheres Enable Topical Delivery of Biologics Through the Skin
Advanced Healthcare Materials, EarlyView.Rolling ultraminiaturized microneedle spheres (RUMS), created via two‐photon polymerization, unlock effective and painless topical delivery of messenger RNA (mRNA) and drugs through the skin. By gently forming thousands of microscopic pores, RUMS boost skin permeability by up to 100‐fold.
