高再现性、大规模喷墨印刷的银纳米颗粒-油墨SERS基底
Highly reproducible, large scale inkjet-printed Ag nanoparticles-ink SERS substrate
摘要：
我们报道了一种低成本，高重现性的大规模表面增强拉曼光谱基板使用喷墨印刷银纳米粒子墨水（AgNI）的制造。使用BPY作为分子探针对AgNI SERS基底进行了SERS评价。印刷的AgNI点阵列表现出优异的SERS性能和再现性。批与批、点与点的标准偏差值均小于10%。实验结果表明AgNI SERS点阵列具有良好的重复性，并具有作为SERS基底的潜在应用价值。
英文摘要：
We report the fabrication of a low cost, and highly reproducible large scale surface-enhanced Raman spectroscopy substrate using an inkjet-printed Ag nanoparticle ink (AgNI). The AgNI SERS substrates were evaluated for SERS using BPY as a molecular probe. The printed AgNI dot arrays exhibit an excellent SERS performance and reproducibility. The batch to batch and spot to spot standard deviation value of less than 10 percent was obtained. The results reveal the reproducibility of the AgNI SERS dot arrays and its potential application for SERS substrates.
