利用纳米金的表面等离子激元激发，在制备过程中增强其斥力，控制其聚集，成功地制备出二维高有序金纳米粒子阵列。通过扫描电镜观察和光谱测量，我们在考虑粒子隔离的情况下评估了金纳米颗粒二维阵列的顺序。此外，二维阵列的高阶性为拉曼测量提供了更高的灵敏度和更高的再现性。从这些结果来看，我们所制备的金纳米颗粒二维阵列有望应用于分子传感器。
We succeeded to fabricate a two-dimensional array of gold nanoparticles with high-ordering by using the surface plasmon excitation of gold nanoparticles for enhancing the repulsive force and controlling the aggregation through the process of fabrication. From SEM observations and spectroscopic measurements, we evaluated the order of the two-dimensional array of gold nanoparticles while taking account of particle isolation. Moreover, the high-ordering of the two-dimensional array provides higher sensitivity and higher reproducibility of Raman measurements. From these results, it is expected that our fabricated two-dimensional array of gold nanoparticles will lead to applications for a molecular sensor.
