A low-cost plasmonic nanopillar array was synthesized using soft thermal nanoimprint lithography, and its sensitivity was determined through far-field spectroscopic measurements. Its transmission spectrum was highly dependent on the refractive index of the surrounding medium, with its sensitivity being 375 nm per refractive index unit according to the spectral shift. Moreover, a simple sensor whose reflected color changed with a change in the plasma frequency on varying the surrounding medium was fabricated.
采用软热压印纳米光刻技术合成了低成本等离子体纳米柱阵列，并通过远场光谱测量确定了其灵敏度。其传输光谱高度依赖于周围介质的折射率，根据光谱位移，其灵敏度为每折射率单位 375nm。此外，还制作了一种简单的传感器，其反射颜色随周围介质中等离子体频率的变化而变化。
