Exploring the generality of ligands for Silica-Encapsulated nanoclusters as SERS labels

We developed a general enhancement strategy to greatly expand the number of SERS labels. We selected 9, 14 and 15 SERS labels and obtained four kinds of complex SERS spectra by using the single ligand mixing strategy. Through our expansion of 26 single-ligand SERS labels, the SERS spectrum library can be greatly expanded.
