美国哈佛大学和麻省理工学院的科研人员近日用金银等材料铸造出无机纳米颗粒。这项重大突破或可对激光技术、显微术、太阳能电池、电子器件、环境监测、环境试验、疾病监测等领域产生促进作用。该研究相关论文10月9日刊登在美国《科学》杂志上。这是人类历史上首次根据用户指定的三维形状,打造仅有25纳米甚至更小的无机纳米粒子,同时误差小于5纳米。一张纸的厚度都有将近十万纳米。
Researchers at Harvard University and Massachusetts Institute of Technology recently used inorganic materials such as gold and silver to cast inorganic nanoparticles. This major breakthrough may have stimulating effects in areas such as laser technology, microscopy, solar cells, electronics, environmental monitoring, environmental testing and disease surveillance. The research related papers published in the United States on October 9 “Science” magazine. This is the first time in human history, according to user-specified three-dimensional shape, to create inorganic nanoparticles only 25 nanometers or less, while the error is less than 5 nm. The thickness of a piece of paper has nearly 100,000 nanometers.
