Mussel-Inspired Membrane Encapsulation Strategy for Developing Long-Acting Glucose-Responsive Injectable Insulin Crystals.
Inspired by the catechol-lysine synergy and oxidative cross-linking mechanisms in mussel adhesion, we have synthesized poly-l-lysine (PLL) modified with 3,4-dihydroxyphenylacetic acid (DOPAC) to encapsulate insulin crystals. Upon oxidation, a dense, stable, and uniform membrane with nanochannels is in situ formed on th...
