Nanoparticles provoke immune response against tumors but avoid side effects（图）
纳米颗粒 肿瘤 免疫反应
2023/6/6
Cancer drugs that stimulate the body’s immune system to attack tumors are a promising way to treat many types of cancer. However, some of these drugs produce too much systemic inflammation when delive...
Engineers at MIT and the University of Massachusetts Medical School have designed a new type of nanoparticle that can be administered to the lungs, where it can deliver messenger RNA encoding useful p...
Researchers at MIT have developed a technique for precisely controlling the arrangement and placement of nanoparticles on a material, like the silicon used for computer chips, in a way that does not d...
Engineers develop nanoparticles that cross the blood-brain barrier（图）
血脑屏障 纳米颗粒 胶质母细胞瘤 化疗药物
