The search for a method to fabricate nonspherical colloidal particles from a variety of materials is of growing interest. As the commercialization of nanotechnology continues to expand, the ability to translate particle-fabrication methods from a laboratory to an industrial scale is of increasing significance. In this feature article, we examine several of the most readily scalable top-down methods for the fabrication of such shape-specific particles and compare their capabilities with respect to particle composition, size, shape, and complexity as well as the scalability of the method. We offer an extensive examination of particle replication in nonwetting templates (PRINT) with regard to the versatility and scalability of this technique. We also detail the specific methods used in PRINT particle fabrication, including harvesting, purification, and surface-modification techniques, with an examination of both past and current methods.
寻求一种能够从各种材料中制造非球形胶体颗粒的方法，这一点越来越受到关注。随着纳米技术的商业化不断扩展，将颗粒制造方法从实验室转化为工业规模的能力变得越来越重要。在这篇专题文章中，我们研究了几种最易于扩展的自上而下的方法，用于制造这种具有特定形状的颗粒，并比较了它们在颗粒成分、尺寸、形状和复杂性以及方法的可扩展性方面的能力。我们对非润湿模板中的粒子复制（PRINT）技术进行了广泛的考察，以了解该技术的多功能性和可扩展性。我们还详细介绍了 PRINT 颗粒制造中使用的具体方法，包括收获、纯化和表面改性技术，并对过去和现在的方法进行了考察。
