Sustainable Hydrogel‐Forming Microneedle‐Reservoir Patches for Transdermal Delivery of Hydrophilic Macromolecules: Biopolymers, Green Manufacturing and Translation
ABSTRACT Hydrophilic biomacromolecules, including insulin, peptides, proteins and vaccine antigens, have transformed modern therapeutics, yet their delivery remains dominated by injections because the stratum corneum (SC) severely restricts passive transport of large and polar molecules. Microneedles have created a rou...
