纳米材料的密度梯度离心分离的研究进展（上）
Recent progresses in density gradient centrifugation separation of nanomaterials
摘要
Abstract
Due to the quantum size eff ect,the properties of nanomaterials are closely connected with their size and morphology,but it is hard to control for most solution based synthesis. Therefore, developing nanoseparation methods to obtain monodisperse nanostructures is of great significance for their application. As a versatile and highly efficient separation method with tunable separation systems,density gradient centrifugation separation method can separate various nanostructures synthesized in diff erent environments,mainly according to their diff erences in size and shape. In this paper,the mechanism,separation method,various separation systems and practical application of the density gradient centrifugation were illustrated,recent research progresses were reviewed and future development was prospected.关键词
