PlasCode - Plasmonic Coding in Smart Mesoscopic Particles for Dynamic Detection in Fluid Flows
Final Report Abstract
The research work in the project has impressively shown that the realization of plasmonic coding can be considered an achievable goal. In particular, the gap plasmonic structures (metal-insulator-metal) have proven to be extremely suitable for successfully meeting the requirements of angular independence. For the less advantageous spectral widths (FWHM) of the angle-independent spectral components, an improved solution was proposed: the combination of Fabry-Perot cavities with nanohole gratings on a common surface. The manufacturing processes developed have proven to be extremely suitable for cost-effective mass production on large surfaces. A process suitable for mass production was also successfully established as part of the production of plasmonic-coded particles using laser cutting. This involved placing the plasmonically prepared films on a pre-structured base that can be held under vacuum. This was followed by targeted laser cutting of the cube geometry. The cubes were then folded by applying a vacuum. Particular attention was paid to suitable locking mechanisms to ensure the permanent positioning of all surfaces of the cubes and thus high overall stability. The resulting structures proved capable of trapping small microparticles and the plasmonic signature of the cubes was successfully identified in the experiment. Despite these successes, some planned aspects were not achieved due to time delays, including detection in the continuous fluid flow as originally planned.
