Abstract

The invention discloses a nano metal organic frame cavitation material, a synthesis method and an application thereof, and belongs to the field of ultrasonic cavitation materials. The material uses a nano-metal organic framework as a carrier, and a cavitating agent active component as a load. The preparation method of the material includes the following steps: 1) dissolving the metal source and the organic ligand in a solvent, respectively, to obtain metal source mother liquor and organic ligand mother liquor; 2) mixing the metal source mother liquor and organic ligand mother liquor obtained in step 1) according to the ratio, performing heating reaction, centrifugal separation, and drying to obtain a dry product; 3) combining the obtained dry product with The active components of the cavitating agent are dispersed in the solvent, centrifuged and dried after stirring. Compared with the lipid bubbles used in the prior art, the nano metal organic framework cavitation material of the present invention can significantly improve the stability, prolong the circulation time in the body, increase the enrichment rate of the material in the tumor site, and improve the Treatment efficacy.

Description

technical field [0001] The invention belongs to the field of ultrasonic cavitation materials, and in particular relates to a nanometer metal organic framework cavitation material, a synthesis method and an application. Background technique [0002] At present, nanocarrier technology has been widely used in the field of biomedicine. Due to the rapid growth and abnormal vasculature of tumors, nanocarriers can accumulate at tumor sites through the penetration and retention (EPR) effect. The main bottleneck is to increase the enrichment rate at the tumor site, and the accumulation analysis of tumors shows that only a small part of the injected nanocarriers can reach the tumor tissue (about 0.7%). Furthermore, there has been no significant improvement in this parameter over the past few decades. Tumors in different patients or in different regions of the same patient will also cause uneven distribution of nanocarriers in the tumor due to tumor heterogeneity. In addition, higher...
