随着纳米科技的快速发展,纳米粒子的分离已经成为纳米领域的基础性研究课题,同时也是热点与难点问题.该文介绍了几种较为常用的分离纳米粒子的方法,主要包括场流分级法、超速离心法、膜分离法、色谱分离法和磁性分离法,评述了每种方法的优缺点、适用范围、具体应用实例和相关研究进展,并具体讨论了每种分离方法的分离效果、重复性和特异性等.
The separation of nanoparticles has been one of the fundamental but difficult hotspots in the rapid-developed fields of nanotechnologies.In this review, the main methodologies for separation of the nanoparticles, including field flow fraction, ultracentrifugation, membrane separation, chromatography and magnetic separation method, are briefly introduced.The advantages and disadvantages, the specific application examples and research progresses of each method are evaluated.These separation methods are also discussed in respects of the separation effect of the samples, reusability and specificity.
