This invention discloses nanoparticles for loading dihydroberberine, their preparation method, and applications. The nanoparticles comprise polydopamine (PDA) and polyethylene glycol modified with the PDA. The polyethylene glycol can be amino-NH2-terminated polyethylene glycol. In preparing the nanoparticles, dopamine hydrochloride is oxidatively self-polymerized under alkaline conditions to obtain PDA nanoparticles; the PDA nanoparticles are then modified with polyethylene glycol to obtain the nanoparticles. Utilizing the aromatic ring structure of the PDA in the nanoparticles, dihydroberberine can be stably loaded onto the nanoparticle surface through π–π stacking interactions and hydrogen bonding. These nanoparticles can effectively load and stably encapsulate dihydroberberine without complex chemical modifications to the dihydroberberine molecule, and are relatively safe and biocompatible.
