The decoration of 2D nanostructures using heteroepitaxial growth is of great importance to achieve functional assemblies employed in biomedical, electrical, and mechanical applications. Although the functionalization of polymers before self-assembly has been investigated, the exploration of direct surface modification in the third dimension from 2D nanostructures has, to date, been unexplored. Here, we used living crystallization-driven self-assembly to fabricate poly(ε-caprolactone)-based 2D platelets with controlled size. Importantly, surface modification of the platelets in the third dimension was achieved by using functional monomers and light-induced polymerization. This method allows us to selectively regulate the height and fluorescence properties of the nanostructures. Using this approach, we gained unprecedented spatial control over the surface functionality in the specific region of complex 2D platelets.

调整三维自组装二维血小板的功能

使用异质外延生长装饰二维纳米结构对于实现生物医学、电气和机械应用中的功能组装非常重要。尽管已经研究了自组装之前聚合物的功能化，但迄今为止，尚未探索从二维纳米结构进行三维直接表面改性的探索。在这里，我们使用活结晶驱动的自组装来制造尺寸可控的基于聚（ ε-己内酯）的二维片晶。重要的是，通过使用功能单体和光诱导聚合实现了血小板的三维表面改性。这种方法使我们能够选择性地调节纳米结构的高度和荧光特性。使用这种方法，我们对复杂二维血小板特定区域的表面功能获得了前所未有的空间控制。
