Flow chart of thrombolysis process and relative level of thrombolysis. a A flow chart of thrombolysis process. 1 A blood clot was placed in a well of a 96-well plate; 2 the nanomachine was added directly onto the blood clot and the locating device reacted with the blood clot; 3 urokinase (80 μl) was added into the well; 4 thrombolysis; 5 residual blood clot; 6 liquid mixture after thrombolysis; 7 liquid supernatant after centrifugation for 5 min at 1500 rpm; and 8 liquid supernatant without the nanomachine after centrifugation for 30 min at 35,000 rpm. b The relative level of thrombolysis. Group A with nanomachine and group B without nanomachine (control group). The liquid mixture in chart was centrifuged at 1500 rpm
