Release date: 2015-06-09 Implanted vascular stents can cause stenosis, resulting in poor blood flow. Cancer patients will weaken or even die after chemotherapy. This is because the biomaterials currently used cannot meet the biocompatibility requirements, and there are different degrees of side effects in clinical applications. . How to design and improve the biocompatibility of biomedical materials, the surface modification technology of cell membrane polymer is applied to the preparation of nanocarriers for targeted drugs, like "invisible biological missiles", eliminating the side effects of drug treatment such as cancer chemotherapy. The research team led by Professor Gong Yongkuan of the College of Chemistry and Materials Science of Northwestern University has made new progress. The reporter learned from Northwest University on the 4th that the research team led by Gong Yongkuan has worked hard for 12 years to complete the research results of “surface modification technology and application of cell membrane structure polymer†and passed the scientific and technological achievements organized by the Science and Technology Department of Shaanxi Province. Identification. The review panel believes that the results have reached the international leading level in the construction of cell-like membrane structure coating technology and the main performance indicators of modified artificial lung. It is reported that the research team has established a phosphorylcholine group that exerts biocompatibility in the outer membrane of the cell, and a functional group capable of immobilizing on the surface of the material, combined at the end of different side chains of the polymer, and is easy to use. A method for surface modification of a cell-like membrane structure polymer with excellent universality and excellent biocompatibility. “The result is a simple surface coating method that creates a stable cell-like membrane structure coating on almost any biomaterial surface.†Gong Yongkuan said that the surface is coated with a fixed coating that overcomes existing international products. The potential hazard of cell-like membrane coating shedding also reduces the coagulation and thrombosis of biomaterials and their medical device products, and inhibits rejection. The biomaterials and medical device products currently used can be modified by cell-like membrane coating technology. Sexual processing.
