目前纳米科学和技术的努力和成功与功能材料和器件的制造有关，在这些材料和器件中，单个单元及其空间排列被工程设计到纳米级。实现这一目标的一个有希望的方法是通过组装胶体无机纳米晶作为新的物质构建块。这一趋势是由各种尺寸和形状的坚固和易于加工的纳米晶体的湿化学合成方面的重大进展所刺激的。溶液生长纳米结构结构复杂程度的增加似乎是纳米科学将越来越多地向其发展的自然方向之一。最近，几个研究小组确实设计了创新的纳米晶体合成方法，通过这种方法，他们能够将具有不同性质的无机材料分组到同一粒子中。这些方法正在为开发能够执行多种技术任务的纳米级物体铺平道路。在这篇综述中(参考文献165篇)，我们将总结胶体纳米晶体的最新研究进展，重点介绍纳米异质结构的制备策略，以及纳米异质结构的性质和发展前景。
Current efforts and success of nanoscale science and technology are related to the fabrication of functional materials and devices in which the individual units and their spatial arrangement are engineered down to the nanometer level. One promising way of achieving this goal is by assembling colloidal inorganic nanocrystals as the novel building blocks of matter. This trend has been stimulated by significant advances in the wet-chemical syntheses of robust and easily processable nanocrystals in a wide range of sizes and shapes. The increase in the degree of structural complexity of solution-grown nanostructures appears to be one of the natural directions towards which nanoscience will increasingly orient. Recently, several groups have indeed devised innovative syntheses of nanocrystals through which they have been able to group inorganic materials with different properties in the same particle. These approaches are paving the way to the development of nanosized objects able to perform multiple technological tasks. In this critical review (165 references), we will summarize the recent advances in the synthesis of colloidal nanocrystals, with emphasis on the strategies followed for the fabrication of nano-heterostructures, as well as on their properties and the perspectives in this field.
