Herein, we report a multifunctional nanodrug (Au NRs@DSFDSs NPs) by coating a drug self-framework delivery system (DSFDS) on Au NRs with absorption at 1300 nm via simple condensation polymerization, with the purpose of developing an efficient theranostic nanoagent with multi-modal imaging ability, and synergistic chemo-photothermal therapy (CT-PTT) for the monitoring and suppression of tumor growth. Thus, this strategy provides a new idea for the design of a multifunctional platform for the accurate and effective image-guided treatment of tumors.
