一个通用的，真空紫外辅助宏观制造的六边形排列的银纳米粒子阵列与控制周期性使用相分离的两亲性二嵌段共聚物膜作为模板被证明在柔性或刚性基板上。在Ag+被选择性地引入到所形成的亲水性纳米柱中之后，通过施加172 nm光子源来实现Ag+的光还原和共聚物模板的伴随蚀刻（参见图）。
A versatile, vacuum-ultraviolet-assisted macroscopic fabrication of hexagonally arranged Ag-nanoparticle arrays with controlled periodicity by using phase-segregated amphiphilic diblock copolymer films as templates is demonstrated on either flexible or rigid substrates. After Ag+ is selectively incorporated into the formed hydrophilic nanocylinders, both the photoreduction of Ag+ and a concomitant etching of the copolymer template are achieved by applying a 172 nm photon source (see figure).
