我们介绍NanoPen,一种新的技术,用于低光功率强度,灵活,实时可重构,以及单个或多个纳米颗粒(如金属球形纳米晶体)和一维纳米结构(如碳纳米管)的大规模光致图案化。NanoPen能够在几秒钟内以<10 W/cm 2的光强度(使用商业投影仪)在数千μm2的区域内动态图案化纳米颗粒。使用此功能演示了各种任意纳米颗粒图案和阵列(包括覆盖0.025 mm 2面积的10 x 10阵列)。NanoPen的一个应用是通过形成表面增强拉曼光谱(Sers)热点,通过图案化金纳米粒子的直径为90 nm,增强因子超过107和皮摩尔浓度灵敏度。
We introduce NanoPen, a novel technique for low optical power intensity, flexible, real-time reconfigurable, and large-scale light-actuated patterning of single or multiple nanoparticles such as metallic spherical nanocrystals, and one-dimensional nanostructures such as carbon nanotubes. NanoPen is capable of dynamically patterning nanoparticles over thousands of μm2 areas with light intensities <10 W/cm2 (using a commercial projector) within seconds. Various arbitrary nanoparticle patterns and arrays (including a 10×10 array covering a 0.025 mm2 area) are demonstrated using this capability. One application of NanoPen is presented through the creation of surface-enhanced Raman spectroscopy (SERS) hot-spots by patterning gold nanoparticles of 90 nm diameters with enhancement factors exceeding 107 and pico-molar concentration sensitivities.
