  • Title: Highly selective SERS probe for Hg(II) detection using tryptophan-protected popcorn shaped gold nanoparticles.
    Author: Senapati T, Senapati D, Singh AK, Fan Z, Kanchanapally R, Ray PC.
    Journal: Chem Commun (Camb); 2011 Oct 07; 47(37):10326-8. PubMed ID: 21853207.
    Abstract:
    Contamination of the environment with toxic Hg(II) is becoming a huge concern throughout the world now. Driven by the need, this communication reports for the first time a tryptophan protected popcorn shaped gold nanomaterials based SERS probe for rapid, easy and highly selective recognition of Hg(II) ions in the 5 ppb level from aqueous solution, with high sensitivity and selectivity over competing analytes. We demonstrate that our SERS assay is capable of measuring the amount of Hg(II) in alkaline battery.
