平行的，线性的金纳米粒子阵列与周期性的横向间距已通过模板组装创建。模板是从头设计的肽，其自组装成表现出层状形态的β-折叠原纤维。带正电荷的赖氨酸残基在纤维宽度上的规则排列以及与带负电荷的金纳米颗粒的互补静电相互作用将颗粒引导成线性阵列（见图）。
Parallel, linear gold nanoparticle arrays with a periodic lateral spacing have been created via templated assembly. The template is a de novo designed peptide that self-assembles into beta-sheet fibrils exhibiting a laminated morphology. Regular arrangement of positively charged lysine residues across the width of the fibril and complementary electrostatic interactions with negatively charged gold nanoparticles directs the particles into linear arrays (see figure).
