Fig. 1From: Rational design of Raman-labeled nanoparticles for a dual-modality, light scattering immunoassay on a polystyrene substrateA comparison of the spectral emission width and structure of fluorescent and SERS probes. The spectral emission width of SERS probe is much narrower than fluorescent probes. The narrow spectral emission width of SERS probes enables the light scattering signal from multiple SERS probes to be detected simultaneously without peak overlapBack to article page
