Nanoparticles derived from tea leaves could be the key to a leap forward in treating lung cancer, scientists have "accidentally" discovered. 科学家近日“意外”发现，从茶叶中提取的纳米颗粒可能是突破治疗肺癌的关键所在。 The joint Swansea University and Indian team was amazed to discover the "quantum dots" they manufactured destroyed 80% of the lung cancer cells they were applied to. 英国斯旺西大学和印度团队的联合小组惊讶地发现，他们制出的“量子点”杀死了80%标记过的癌细胞。 Quantum dots are tiny nanoparticles. They can be made chemically, but this is complicated and expensive and has toxic side effects. 量子点是极小的纳米颗粒，可用化学方法制成，但这种方法非常复杂且成本高昂，还伴有毒副作用。 |
