The invention relates to a targeting development microbubble for tumor 
ultrasound treatment. The targeting development microbubble comprises a 
lipid bilayer shell, a targeting polypeptide or 
protein derivative fixed at the outer side of the shell, a biological 
inert gas encased in the shell and 
blood coagulation factors and 
drug particles which are dispersed in the shell. The targeting developmentmicrobubble not only can perform high-frequency ultrasonic development to detect and diagnose tumors, but also can specifically adsorb tumor blood vessels through the targeting polypeptide or proteinderivative at the outer side of the 
lipid bilayer shell, and performs concentrated 
cavitation under the action of 
ultrasound to release the 
blood coagulation factors for rapidly forming capillary 
embolization, thereby achieving the purpose of treating the tumors. In addition, during microbubble 
cavitation, the 
drug particles are released into a tumor 
vascular embolization substance, so that a 
drug is slowly released, and the tumors are treated. The targeting development microbubble has extremely important significance for the diagnosis and treatment of the tumors. Furthermore, the invention relates to a preparation method of the targeting development microbubble for the tumor 
ultrasound treatment.
