To improve the efficiency of cancer therapy, we developed multifoliate PEGylated PtRu bimetallic nanocomplexes (PtRu-PEG BNCs) as multifunctional theranostic nanoagents for computed tomography (CT) imaging and synergistic thermoradiotherapy. The synthesized PtRu-PEG BNCs with uniform size and morphology exhibit excellent stability, notable photothermal effect, and good biocompatibility. As compared with other platinum nanomaterials, the PtRu-PEG BNCs are able to absorb near-infrared laser energy and present excellent photothermal conversion efficiency (44.5%). Multifoliate PtRu-PEG BNCs can be applied to CT imaging and radiotherapy (RT) because of the presence of platinum. Unlike a single therapy method, the integration of photothermal therapy with RT can effectively induce cell apoptosis and generate an obvious synergistic effect. Hence, the as-prepared nanocomplexes can be used as multifunctional theranostic nanoagents.
