Immobilization of ordered plasmonic nanostructures at surfaces of polymeric melts

由于其等离子体性质，金纳米颗粒（AuNP）对于感测应用如表面增强拉曼光谱（Sers）是令人感兴趣的。到目前为止，在实验室规模的AuNP结构的组装和纳米光子表征与在制造相关工艺中的这种纳米结构的集成之间存在差距。该项目的目的是缩小这一差距。为此，必须研究单个纳米颗粒和纳米颗粒结构与聚合物熔体之间的相互作用，特别是在注塑成型和3D打印（熔融沉积成型）期间的结构保持集成方面。Sers作为模型应用，因为结构完整性在这里非常重要，同时可以获得有关加工过程中出现的反应过程的知识。作为一个长期的目标，光学功能器件的微流体流通池应获得大量。

Due to their plasmonic properties gold nanoparticles (AuNP) are interesting for sensing applications, like Surface Enhanced Raman Spectroscopy (SERS). So far a gap between the assembly and nano-photonic characterization of AuNP-structures in lab-scale and the integration of such nanostructures in manufacturing relevant processes exists. The aim of this project is to close this gap. For that purpose the interplay between single nanoparticles and nanoparticle structures with polymer melts has to be investigated, particularly with regard to structure preserving integration during injection molding and 3D printing (fused deposition modeling). SERS serves as model application, as structural integrity is of great importance here and at the same it is possible to gain knowledge about reaction processes that appear during processing. As a long-term goal optical functional devices for microfluidic flow-through cells should be made accessible in large numbers.
