Here, a completely new readout technique, so-called "Click" SERS, has been developed based on Raman scattered light splice derived from nanoparticle (NP) assemblies. The single and narrow (1-2 nm) emission originating from triple bond-containing reporters undergoes dynamic combinatorial output, by means of controllable splice of SERS-active NPs analogous to small molecule units in click chemistry. Entirely different to conventional "sole code related to sole target" readout protocol, the intuitional, predictable and uniquely identifiable "Click" SERS is relies on the number rather than the intensity of combinatorial emissions. By this technique, 10-plex synchronous biomarkers detection under a single scan, and accurate cellular imaging under double exposure have been achieved. "Click" SERS demonstrated multiple single band Raman scattering could be an authentic optical analysis method in biomedicine.
