样品前处理是复杂基体中痕量分析物定性定量分析的关键步骤。沿着纳米技术在材料科学中的迅速发展，许多纳米材料被开发出来，在分析化学中具有特别有用的应用。纳米材料由于其高比表面积、高表面活性和前所未有的物理/化学性质，在快速高效制备样品方面的潜力得到了广泛的利用。本文综述了近年来新型纳米材料在样品制备中的应用研究进展。纳米粒子和纳米多孔材料在样品制备中的不寻常的性能进行了评估。各种组成和功能化扩展了纳米材料在样品制备中的应用，并且从纳米多孔材料的多样化孔结构产生不同的尺寸和形状选择性。如此大的多样性使纳米材料成为一种多功能的工具，用于几乎所有类别的分析物的样品制备。
Sample preparation is a key step for qualitative and quantitative analysis of trace analytes in complicated matrix. Along with the rapid development of nanotechnology in material science, numerous nanomaterials have been developed with particularly useful applications in analytical chemistry. Benefitting from their high specific areas, increased surface activities, and unprecedented physical/chemical properties, the potentials of nanomaterials for rapid and efficient sample preparation have been exploited extensively. In this review, recent progress of novel nanomaterials applied in sample preparation has been summarized and discussed. Both nanoparticles and nanoporous materials are evaluated for their unusual performance in sample preparation. Various compositions and functionalizations extended the applications of nanomaterials in sample preparations, and distinct size and shape selectivity was generated from the diversified pore structures of nanoporous materials. Such great variety make nanomaterials a kind of versatile tools in sample preparation for almost all categories of analytes.
