Assembly of bimetallic (Au–Ag)FON composite films at liquid/solid interfaces and their tunable optical properties

Abstract

The regular structure provided by two-dimensional (2D) structural colloidal crystals is widely accepted to provide an ideal template that ensures that plasmonic bimetallic composite nanostructures are uniform. Herein, we report...

High-throughput surface-enhanced Raman scattering sensors for near-infrared detection of biochemical molecules

“…[25][26][27][28][29][30] Therefore, porous Au and Ag NPs are the ideal choices for NIR-SERS substrates. [31][32][33][34] Currently, the reported preparation methods of porous NPs based substrates mainly include templating, 35,36 dealloying, 37 and electrodeposition. 38,39 The substrates prepared by these methods generally feature a high-density hot spot and sensitivity, and can be prepared on a large-scale.…”
