The invention relates to the field of biotechnology, and specifically discloses an iRGD magnetic targeting microbubble contrast agent and its application. ferric oxide nanoparticles. In the present invention, iRGD and ferric oxide nanoparticles are co-loaded in PLGA microbubbles, which further improves the effect of PLGA microbubbles targeting new microvessels, realizes ultrasound/magnetic resonance dual mode imaging, and is beneficial to observe endometrial angiogenesis process of change. |
