Hydrogel Patch: Adhesive Hydrogel Patch with Enhanced Strength and Adhesiveness to Skin for Transdermal Drug Delivery (Adv. Funct. Mater. 42/2020)

In article number 2004407, Jaeyun Kim and co-workers describe a hydrogel patch with enhanced strength and high adhesiveness to skin tissue. The incorporation of mesoporous silica nanoparticles within the polydopamine-based hydrogel and between the hydrogel-tissue interface leads to significant enhancements of adhesiveness of the hydrogel to skin. The rapid adhesion and sustained drug delivery through the skin could allow for a hydrogel patch for transdermal drug delivery.
