The interaction between metallic nanoparticles creates highly enhanced, localised electric fields and has recently emerged as a strategic area widely applicable across physics, chemistry and biology for sensing, optoelectronics and optical films. The novel optical signatures of larger, highly symmetric nanoparticle assemblies may be drastically changed by breaking the structural symmetry, leading to unique phenomenon such as Fano-like resonances. This project aims to extend metal nanoparticle assemblies to include fluorophores in well-defined positions, creating an inherent and switchable symmetry breaking. Inclusion of additional functionality into such structures is essential for their use in smart optical films and switchable devices.

金属纳米颗粒之间的相互作用产生高度增强的局部电场，最近已成为广泛适用于物理，化学和生物学的传感，光电子和光学薄膜的战略领域。较大的、高度对称的纳米颗粒组装体的新颖光学特征可以通过破坏结构对称性而急剧改变，从而导致诸如Fano样共振的独特现象。该项目旨在扩展金属纳米颗粒组件，以在明确定义的位置包括荧光团，从而创建固有的和可切换的对称性破缺。将额外的功能纳入此类结构对于它们在智能光学膜和可切换装置中的使用是必不可少的。
