Abstract
A covalent organic framework (COF)-engineered polydopamine core-shell nanoplatform (PDA@COF) was developed. The ultrasmall pores and abundant functional sites of the COF endowed the nanoplatform with enhanced drug loading capacity and diminished drug leakage effect. Multimodal imaging-guided photothermal chemo-synergistic tumor-targeted therapy was realized after rational functionalization. This work offers new insights for developing COF-based multifunctional theranostic systems.
