Conventional SERS probes suffer from limited brightness and poor reproducibility and stability making them unsuitable for routine in vivo applications. A novel class of layered SERS probes is demonstrated in which individual nanostructures host electromagnetic hotspots, thus increasing brightness by more than two orders magnitide compared to conventional individual nanostructures.
