PTK2 and Alzheimer disease: Herein, we developed an adhesive, stretchable, and self-healing hydrogel dressing based on borate ester31, embedding polydopamine nanoparticles (PDA NPs) for ROS scavenging and liposome-encapsulated hydrophobic focal adhesion kinase inhibitor (FAKi-lipo) for FAK inhibition to synergistically treat AD (Fig. 1)32.
