TL;DR: Ultraabright gap-enhanced Raman tags with external hot spots with strong electromagnetic hot spots from interior sub-nanometer gaps and external petal-like shell structures, larger immobilization surface area, and Raman cross section of reporter molecules are reported.

TL;DR: A PUF label fabricated by drop-casting aqueous GERTs, high-speed read using a confocal Raman system, digitized through coarse-grained coding methods, and authenticated via pixel-by-pixel comparison is demonstrated.

TL;DR: In this paper, the photostability of SERS nanoprobes with different embedded Raman reporters, number of shell layer, or nanoparticle shapes was investigated, and it was shown that double metallic-shell off-resonant gap-enhanced Raman tags with 1,4-benzenedithiol molecules showed the best performance, to the best of their knowledge, with a photobleaching time constant up to 4.8 × 105 under a laser power density of 4.7 × 105 W cm−2.

TL;DR: This tutorial provides the basic principles of SERS and SERS nanotags, including recent progress of Sers-based bioimaging applications, as well as the outlooks into the future developments toward practical clinical SERS.

TL;DR: A kind of unique multifunctional nanoprobes with computed X-ray tomography/magnetic resonance/surface-enhanced Raman spectroscopy (CT/MR/SERS) triple-modal imaging capabilities are designed and show critical clinical significance on the improvement of tumor diagnosis and therapy.
