The present invention improves the extremely simple and less invasive therapy that does not cause serious side effects and radiation exposure by the agent and attacks the tumor cells, and is used for therapy that enables radical cure. The purpose is to provide an agent. According to the present invention, by utilizing the EPR effect specific to tumor cells, the tumor cells are covered with the tissues by fine particles that permeate only the tumor blood vessels and accumulate and settle in the tumor, and do not release the angiogenesis inducing factor. After passing through the gap between 50 nm to 500 nm of tumor vascular endothelial cells, which does not separate and move the tumor cells with improved motility in the oxygen state, and adheres to the tumor cells and extracellular matrix near the gap, Provided is a tumor sealant characterized by biodegradation. |
