α‑Lipoic Acid-Based Wet-Adhesive Supramolecular Powder Promotes Oral Mucosa Healing by Inhibiting NF-κB Signaling.
Oral mucosal lesions present significant therapeutic challenges due to the complex oral environment and the limitations of conventional biomaterials in clinical application. Herein, a self-gelling supramolecular powder composed of polyethyleneimine (PEI), poly (acrylic acid) (PAA), and α-lipoic acid (LA) is developed f...
