The present invention provides a micro-nano structure formed by self-assembling a compound represented by formula (I), an isomer thereof, a pharmaceutically acceptable salt, a hydrate or a solvate in an aqueous solution, a preparation method for the micro-nano structure, and use thereof. The micro-nano structure has the advantages of having high photothermal conversion efficiency, good photothermal stability, good photothermal effect and photodynamic effect, being easily degraded, and having high safety, and can be passively targeted to tumor sites, having a broad prospect in the diagnosis and treatment of cancers and skin diseases.
