Abstract

Hollow nanoparticles with tunable structures and spatial and chemical specificity are considered as promising carriers. However, it remains a formidable challenge to endow hollow nanomaterials with precisely controlled multisized macro/mesoporous structures up to now. This paper demonstrates a “polydopamine (PDA) expansion–shrinkage” strategy combined with a monomicelle interfacial confined assembly method to achieve the highly controllable preparation of a series of yolk@shell PDA@SiO₂ composite nanoparticles with structural asymmetry and a tunable multisized pore in the shell. The strategy allows systematic manipulation of the average pore size of large slit pores in the range of 15.4–86.5 nm by adjusting the reaction temperature. Benefiting from advantages such as an asymmetric structure and multilevel porosity, they exhibit excellent performance in the applications of on-demand loading of dual-sized cargoes, dual-propelled nanomotors, and particle size-selected encapsulation and separation. These findings provide inspiration for the construction of asymmetric yolk@shell structures with tunable multisized pores for a wide range of biological and chemical applications.

通过单舱密闭组装构建具有可控多尺寸孔隙结构的卵黄@壳纳米复合粒子

具有可调结构、空间和化学特异性的中空纳米粒子被认为是前景广阔的载体。然而，迄今为止，赋予中空纳米材料精确控制的多尺寸宏观/多孔结构仍然是一项艰巨的挑战。本文展示了一种 "聚多巴胺（PDA）膨胀-收缩 "策略，结合单舱界面约束组装方法，实现了一系列具有结构不对称性和外壳可调多尺寸孔隙的卵黄@壳PDA@SiO2复合纳米粒子的高度可控制备。该策略可通过调节反应温度系统地控制大狭缝孔隙的平均孔径，范围为 15.4-86.5 nm。得益于非对称结构和多级孔隙率等优势，它们在按需装载双尺寸货物、双推进纳米发动机以及颗粒尺寸选择封装和分离等应用中表现出卓越的性能。这些发现为构建具有可调多级孔隙的非对称卵黄@壳结构提供了灵感，可广泛应用于生物和化学领域。
