定义的纳米粒子簇阵列（NCAs）与总的横向尺寸高达25.4 μ m × 25.4 μ m的已制造的顶部10 nm的薄金膜使用模板引导自组装。这种方法提供了对阵列中结构参数的精确控制，允许簇中纳米颗粒的平均数量（n）和边到边间距（λ）在1
Defined nanoparticle cluster arrays (NCAs) with total lateral dimensions of up to 25.4 mu m x 25.4 mu m have been fabricated on top of a 10 nm thin gold film using template-guided self-assembly. This approach provides precise control of the structural parameters in the arrays, allowing a systematic variation of the average number of nanoparticles in the clusters (n) and the edge-to-edge separation (Lambda) between 1 < n < 20 and 50 nm
