With the development and progress of medical technology, some new medical materials have been widely used
In transdermal drug delivery systems, polymer materials are mostly used as drug carriers, which have good compatibility and adhesion with the skin.
Based on the synergistic effect of adhesion and adsorption, Jaeyun Kim of Sungkyunkwan University in South Korea constructed a tissue adhesion consisting of polyacrylamide/polydopamine (PAM/PDA) and ultra-large pore size mesoporous silica nanoparticles (XL-MSNs) Type hydrogel
Thanks to the molecular interaction between XL - MSNs and polymer chains, the hydrogel has enhanced skin tissue adhesion and strength
This research provides a highly adhesive carrier for the transdermal drug delivery system, which can significantly improve the efficiency of transdermal drug delivery
