Two-electron oxidized polyphenol chemistry-inspired superhydrophilic drug-carrying coatings for the construction of multifunctional nasolacrimal duct stents

A new kind of superhydrophilic drug-carrying coating was synthesized from dopamine and rapamycin to prevent nasolacrimal duct from obstructing through anti-inflammation, anti-infection and anti-fibrosis regulation. This research provides a versatile surface bioengineering strategy.
