Strong and Tough Supramolecular Microneedle Patches with Ultrafast Dissolution and Rapid‐Onset Capabilities
Dissolving microneedle (DMN) patches are emerging as a minimally invasive and efficient transdermal drug delivery platform. Generally, noncrystalline, water‐soluble, and high‐molecular‐weight polymers are employed in DMNs because their sufficient intermolecular interactions can endow the DMNs with n...

Summary: | Dissolving microneedle (DMN) patches are emerging as a minimally invasive and efficient transdermal drug delivery platform. Generally, noncrystalline, water‐soluble, and high‐molecular‐weight polymers are employed in DMNs because their sufficient intermolecular interactions can endow the DMNs with necessary mechanical strength and toughness. However, high viscosity and heavy chain entanglement of polymer solutions greatly hinder processing and dissolution of polymeric DMNs. Here, a strong and tough supramolecular DMN patch made of highly water‐soluble cyclodextrin (CD) derivatives is described. Due to the synergy of multiple supramolecular interactions, the CD DMN patch exhibits robust mechanical strength outperforming the state‐of‐the‐art polymeric DMNs. The CD DMN displays ultrafast dissolution ( |
