Immobilization of ordered plasmonic nanostructures at surfaces of polymeric melts

金纳米颗粒(AuNP)由于具有等离子体性质，在表面增强拉曼光谱(SERS)等传感领域具有广泛的应用前景。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以及这些纳米结构在制造相关工艺中的集成之间存在差距。这个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，特别是在注射成型和3D打印(熔融沉积建模)过程中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，同时也有可能获得关于在加工过程中出现的反应过程的知识。作为一个长期目标，微流控流通池的光学功能器件应该大量实现。

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.
