Literature Information
Huiyuan Guo, Baoshan Xing, Jason C. White, Arnab Mukherjee, Lili He
An innovative and ultra-sensitive surface-enhanced Raman spectroscopic (SERS) method that uses a triple-functional surfactant ligand for nanoparticle surface binding, phase transfer and SERS signal reporting was developed for silver nanoparticle (AgNP) detection. The method was able to detect 100 ng L−1 of AgNPs in aqueous samples and 2 μg g−1 AgNPs in wheat plants.
