英文摘要Integrated theranostic nanosystems that combine therapeutic methods with suitable medical imaging modality are highly needed in the improvement of cancer theranostic approaches. herein, polydopamine (pda)-shelled nayf4:yb,er@nayf4:yb nanoparticles (ucnps) capable of loading indocyanine green (icg) molecules via electrostatic adsorption, hydrophobic interaction and p-p stacking were successfully designed and synthesized (ucnps@pda-icg, denoted as upi) for upconversion imaging and combined photothermal/photodynamic therapy (ptt/pdt) with enhanced antitumor efficacy. we have found that icg in this novel anticancer nanoplatform can be triggered impressively by 808-nm irradiation to produce both a photothermal effect and cytotoxic reactive oxygen species (ros), thus achieving a good ptt/pdt synergistic effect. notably, compared with free icg molecules, upi nanocomposites show much higher photostability and thermal stability. both in vitro and in vivo experiments show that the as-obtained upi can ablate cancer cells effectively with 808-nm irradiation, revealing their great potential as a nir-mediated dual-modal therapeutic platform. meanwhile, the core of ucnps can be used for ucl imaging. all these results demonstrate great potentiality of upi as a novel type of theranostic agent for the treatment of tumors.
