Description

technical field

[0001] The invention relates to the field of nano biomedical materials, in particular to a nano material and its preparation method and application. Background technique

[0002] Malignant tumor, also known as cancer, has been seriously endangering human health and life safety. It has the characteristics of unlimited proliferation, invasion and metastasis, and has surpassed cardiovascular disease to become the most serious disease causing human death. Tumor diagnosis plays an important role in tumor treatment. With the continuous development and updating of medical imaging methods and equipment, a variety of imaging diagnostic methods, including magnetic resonance imaging (MRI), X-ray computed tomography (CT) Imaging methods such as ultrasound imaging (UI), optical imaging (OI) and positron diffraction imaging (PET) are gradually emerging and improving, providing new ideas for tumor detection and location analysis. The multi-modal imaging methods (MRI / CT, ​​...
