摘要:

具有显著表面等离激元共振效应的贵金属纳米粒子因其独特的光电学性质在许多领域表现出了潜在的应用价值. 结合纳米压印技术与自组装技术发展了一种高效的多元化纳米粒子结构的制备方法, 并制备了一种由不同尺寸金纳米粒子构成的周期性表面等离激元纳米粒子结构. 实验结果证明此种方法在大批量制备和结构多元化的控制方面具有独特的优势. 利用不同的表面等离激元纳米粒子结构对不同荧光分子增强效果的差异, 设计了2种具有明显明暗差异的荧光条码, 展示了多重的荧光增强响应.

Abstract:

Noble metal nanoparticles with significant localized surface plasmon resonance effects have demonstrated potential applications in various fields due to their unique optoelectronic properties. Recently, the construction of multiplexed plasmonic nanostructures has been widely conducted. Through combining nanoimprint and self-assembly, an efficient method for the preparation of multiplexed plasmonic nanostructure with different size gold nanoparticles on a large area were developed. Meanwhile, two fluorescent barcodes were designed based on the differences in the effects of surface enhancement fluorescence, which shows a multi-functional fluorescent display.

Key words: Nanoimprint, Self-assembly, Surface plasmon resonance, Nanoparticle structure, Surface enhanced fluorescence(SEF)
