Drug delivery systems assist in natural compounds-based cancer chemoprevention. Diversity delivery platforms (mainly including but not limited to liposomes, polymeric nanocarriers, extracellular vesicles) enhance bioavailability and reducing toxicity of natural compounds, through active-targeting ligand decorated and passive targeting via the enhanced permeability and retention effect.
