Magnetic core/gold shell nanoparticle immunoassay for rapid detection of biomolecules using Raman spectroscopy

摘要

Nanomaterials were adorned with recognition molecules and combined with surface-enhanced Raman scattering to selectively separate, identify, and quantify trace amounts of bioactive molecules from within a complex mixture. This work is presented as a rapid, portable, and cost-effective method that complements existing biomolecule analysis techniques, with potential in-field applications in clinical diagnostics, environmental monitoring, and forensic science.
