Abstract
Description
technical field
[0001] The invention relates to the technical field of medicine for treating tumors, in particular to a nanoparticle for improving the permeability of tumor tissue, its preparation method and application. Background technique
[0002] Cancer is the primary chronic disease that threatens human health, and chemotherapy is the basic method for clinical treatment of tumors. Due to the advantages of long blood circulation, selective tumor enrichment, long residence time in tumor sites, and low toxicity, nanomedicine is expected to overcome the shortcomings of small molecule chemotherapy drugs and improve its antitumor effect. However, the average amount of nanoparticles reaching the tumor site is only 0.7% of the injected dose, and most of the nanoparticles can only stay around the blood vessels and cannot enter the center of the tumor, which greatly limits the therapeutic effect of nanomedicine. For example, Professor Liang Xingjie studied the penetration perfor...
