Deposition of a conformal nanoscale polymer coating was characterized using a fiber SPR sensor. The sensor platform consisted of an unmodified gold-coated single mode fiber where SPR was excited through the coupling of the core mode into the cladding modes using a Tilted Fiber Bragg Grating. The results from this study show how the sensor can monitor in real time the formation of polyelectrolyte coatings during a process consisting of several stages of immersion. The experimental data was further calibrated by simulations and Atomic Force Microscope imaging allowing us to determine the thickness and refractive index of the adsorbed polyelectrolyte.
使用光纤表面等离子体共振（SPR）传感器对共形纳米级聚合物涂层的沉积进行了表征。该传感器平台由未改性的镀金单模光纤组成，通过倾斜光纤布拉格光栅将芯模耦合到包层模中来激发表面等离子体共振。这项研究的结果表明，该传感器如何在一个由几个浸泡阶段组成的过程中实时监测聚电解质涂层的形成。通过模拟和原子力显微镜成像对实验数据进行了进一步校准，使我们能够确定吸附的聚电解质的厚度和折射率。
