Abstract

Patchy nanoparticles (PNPs) possess anisotropic surfaces that produce emergent directionalities in interactions. Manipulation of such surface complexities offers a powerful handle for control over interparticle spatial and orientational orderings, making PNPs an ideal class of nanoscale synthons for self-assembly. However, realization of PNPs with defined patch positions and geometries faces technical challenges related to the level of precision chemistry required to achieve the desired surface patterning. Here, we provide an in-depth review of state-of-the-art strategies available for PNP synthesis. We examine the experimental efforts made to synthesize PNPs, classifying advances based on different material types spanning organic and inorganic systems. We conclude by presenting barriers in PNP synthesis and highlighting ongoing theoretical efforts aimed at guiding experimental design and parameter selection for creating novel surface patterning on NPs.

具有表面复杂性的斑状纳米粒子，可进行定向自组装

摘要补丁状纳米粒子（PNPs）具有各向异性的表面，可在相互作用中产生新的方向性。对这种表面复杂性的操纵为控制粒子间的空间和方向有序性提供了强有力的手段，使 PNPs 成为自组装的一类理想的纳米级合成物。然而，实现具有确定贴片位置和几何形状的 PNPs 面临着技术挑战，这与实现所需的表面图案化所需的精密化学水平有关。在此，我们将对现有的 PNP 合成策略进行深入评述。我们研究了合成 PNP 的实验工作，并根据有机和无机系统的不同材料类型对进展进行了分类。最后，我们介绍了 PNP 合成中的障碍，并重点介绍了正在进行的旨在指导实验设计和参数选择的理论工作，以便在 NPs 上创建新颖的表面图案。图表摘要

期刊介绍： MRS Bulletin is one of the most widely recognized and highly respected publications in advanced materials research. Each month, the Bulletin provides a comprehensive overview of a specific materials theme, along with industry and policy developments, and MRS and materials-community news and events. Written by leading experts, the overview articles are useful references for specialists, but are also presented at a level understandable to a broad scientific audience.
