Plasmonic structures using noble metal nano-assemblies are created and printed or stamped with a seal for use as information tags that carry both authenticity and information. We created an ink that contains stealth nanobeacons and evaluated its printing characteristics. Stealth nanobeacons are composed of noble metal nano-assemblies, which are fabricated a self-assembly process and have indefinite shapes. This plasmonic structure was made into simple ink by mixing it with pure water or existing inkjet printer inks. We discharged this adjusted ink on an inkjet printer to evaluate its surface-enhanced Raman scattering activity and other properties, and confirmed that the ink containing stealth nanobeacons can be printed successfully. The printable ink is expected to be developed into a "Nanotag" information tag and an authenticity tag.
利用贵金属纳米组件制造的等离子体结构被制作出来，并通过印章进行印刷或压印，用作携带真实性和信息的信息标签。我们制备了一种含有隐形纳米信标的墨水，并评估了其印刷特性。隐形纳米信标由贵金属纳米组件组成，这些组件通过自组装过程制造，形状不确定。通过将这种等离子体结构与纯水或现有的喷墨打印机墨水混合，制成了简单的墨水。我们在喷墨打印机上喷出这种调配好的墨水，以评估其表面增强拉曼散射活性和其他特性，并证实含有隐形纳米信标的墨水能够成功打印。这种可打印墨水有望被开发成一种“纳米标签”信息标签和真实性标签。
