PlasCode - Plasmonic Coding in Smart Mesoscopic Particles for Dynamic Detection in Fluid Flows

多功能微容器和微颗粒的应用日益广泛。对这些粒子进行可靠的标记以用于它们的跟踪和识别对于大多数应用来说是必要的。颗粒标记在可靠和有效的颗粒生成中的稳健集成是特别重要的。“PlasCode”项目通过将二维基本（薄膜）结构折叠成三维物体（多面体），并通过光学可读的等离子体结构对颗粒进行标记（编码），将创新性的微粒生成相结合。薄膜折叠的基本方法是基于液体的毛细管力。纳米压印光刻用于在薄膜上产生等离子体结构。在模拟方法和项目框架内的生产过程中，根据等离子体编码对微粒进行优化后，在演示系统的恒定流体流中动态检测微粒。该项目的概念允许随之而来的小型化的编码颗粒下降到更低的微米范围内的尺寸。

Multifunctional micro containers and micro particles find an increasingly wide range of applications nowadays. Reliable labeling of such particles for their tracking and recognition is imperative for most applications. The robust integration of the particle labelling in a reliable and efficient particle generation is particularly important. The project "PlasCode" combines the innovative generation of micro particles by folding of two-dimensional basic (thin film) structures into three-dimensional objects (polyhedra) with the labelling (coding) of the particles by optically readable plasmonic structures. The underlying method for folding (origami) of thin films is based on the capillary forces of liquids. Nanoimprint lithography is used to create the plasmonic structures on the thin films. After the micro particles have been optimized in terms of plasmonic coding both in a simulative approach and in their production within the framework of the project, the particles are dynamically detected in the constant fluidic flow of a demonstrator system. The project concept allows a consequent miniaturization of the coded particles down to dimensions in the lower micrometer range.
