Plasmonic enhancement enabled by silver nanotriangles in Raman spectra of methylene blue

Plasmonic enhancement enabled by silver nanotriangles in Raman spectra of methylene blue

We present a method for detecting Methylene Blue (MB) using Confocal Raman Spectroscopy assisted with plasmonic enhancement from colloidal silver nanotriangles (NTs). The amplified Raman signal from the analyte aggregated over nanoclusters facilitated the detection of concentrations below 10-5 M.
