Block Copolymer Microcapsules with Perpendicularly‐Perforated Ultrathin Membranes for Controlled Transmembrane Transport

open access: yesAdvanced Functional Materials, EarlyView.
Block copolymer microcapsules with ultrathin, perpendicularly perforated membranes are developed through double emulsions, initiated by the diffusion of water into single emulsions. Both shell thickness and channel diameter can be systematically tuned, offering precision in molecular sieving and significantly enhanced permeation rates.

Rolling Ultrasharp Microneedle Spheres Enable Topical Delivery of Biologics Through the Skin

open access: yesAdvanced 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.
