Renal cell carcinoma (RCC) is a common malignant tumor of the urinary system with poor prognosis. Therapeutic drugs for RCC can easily develop resistance or have unignorable toxicity or limited efficiency. Here, the thermosensitive mitochondrial metabolism-interfering anticancer drug lonidamine (LND) was combined with the photothermal material polydopamine (PDA) to treat RCC. To delivery drugs accurately to RCC site, LND and PDA were loaded in stellate mesoporous silica nanoparticles (MSNs) with a large surface area and cloaked with RCC membranes (MLP@M). The results showed that MLP@M exhibited excellent tumor targeting ability. The synergistic effects of LND and PDA in MLP@M were greatly enhanced when triggered by an 808 nm laser. Moreover, the antiproliferative and tumor suppressing abilities were enhanced with good biocompatibility after MLP@M + laser treatment. Additionally, 80% of RCC tumor-bearing mice treated with MLP@M + laser did not relapse. Our study provides a potential therapeutic approach for RCC treatment.
