Selective and sensitive SERS sensor for detection of Hg2+ in environmental water base on rhodamine-bonded and amino group functionalized SiO2-coated Au–Ag core–shell nanorods1. Issue 41 (7th May 2015) - Ma, Pinyi
Abstract A novel SERS sensor for trace detection of Hg2+ using R6G-derive Schiff base bonded Au@Ag@SiO2–NH2 NRs was designed. The LOD is 0.33 pmol L−1.
