Abstract
Due to the high recurrence rate and mortality of venous thrombosis, there is an urgent need for research on antithrombotic strategies. Because of the short half-life, poor targeting capabilities, bleeding complications, and neurotoxic effects of conventional pharmacological thrombolysis methods, it is essential to develop an alternative strategy to noninvasive thrombolysis and decrease the recurrence rate of venous thrombosis. A platelet-mimetic porphyrin-based covalent organic framework-engineered melanin nanoplatform, to target delivery of hirudin to the vein thrombus site for noninvasive thrombolysis and effective anticoagulation, is first proposed. Owing to the thrombus-hosting properties of platelet membranes, the nanoplatform can target the thrombus site and then activate hyperthermia and reactive oxygen species for thrombolysis under near-infrared light irradiation. The photothermal therapy/photodynamic therapy combo can substantially improve the effectiveness (85.7%) of thrombolysis and prevent secondary embolism of larger fragments. Afterward, the highly loaded (97%) and slow-release hirudin (14 days) are effective in preventing the recurrence of blood clots without the danger of thrombocytopenia. The described biomimetic nanostructures offer a promising option for improving the efficacy of thrombolytic therapy and reducing the risk of bleeding complications in thrombus associated diseases.

Abstract
Traditional thrombolytic drugs offer limited outcomes due to short circulation half-life and low utilization. Herein, we have designed and constructed a biological mediator-propelled nanosweeper for highly efficient nonpharmaceutical thrombolysis and prevention of thrombus recurrence. Under the near-infrared light irradiation, the nanosweepers were activated to trigger nitric oxide (NO) release, which propelled the nanosweepers to penetrate deeply into the thrombus and resulted in enhanced site-pecific mechanical and photothermal thrombolysis. The experimental evidence confirmed that the ingenious nanosweeper displayed excellent site-specific thrombolytic efficacy even when compared with the clinical thrombolytic drug. In the meantime, as a biological mediator, the release of NO could effectively prevent thrombus recurrence in vivo. Overall, we anticipated that the nanosweeper would provide a promising strategy for the treatment of thrombi.
