Fig. 2From: Rational design of Raman-labeled nanoparticles for a dual-modality, light scattering immunoassay on a polystyrene substrateSynthesis schema for the production of SERS probes. The labeling and functionalization of concentrated gold nanoparticles during the fabrication of SERS probes is a multistep process, which can be optimized for use with strongly interfering substrates such as polystyreneBack to article page
