The concentration of d-dimer, fluorescence intensity of thrombolysis, and fluorescence microscope images of the supernatant. a The concentration of d-dimer in the supernatant of each subgroup. Data are shown as mean + standard deviation. All A series of samples are nanomachine groups and B series are control groups. *P <0.05 compared with the control groups. b The fluorescence intensity of thrombolysis in the supernatant after the system were centrifuged for 30 min at 35,000 rpm. Data are shown as mean + standard deviation. The A series contains the nanomachine and B series contains the control groups. *P <0.05 compared with the control groups. c Fluorescence microscope images of the supernatant after thrombolysis assisted by 0, 5, 10, and 20 μl nanomachines
