Uniformly controlling a large number of metal nanostructures with plasmonically enhanced signal to generate quantitative optical signals and the widespread use these structures for surface-enhanced Raman scattering (SERS)-based biosensing bioimaging applications are paramount importance but extremely challenging. Here, we report highly controllable, facile selective-interdiffusive dealloying chemistry synthesizing dealloyed intra-nanogap particles (DIPs) ∼2 nm intragap in high yield (∼95%)...
Surface-enhanced Raman scattering (SERS)-based sensing is promising in that it has potential to allow for highly sensitive, selective, and multiplexed detection imaging. However, the controlled assembly gap formation between plasmonic particles generating strong SERS signals a quantitative manner challenging, especially on biodetection platforms, particle-to-particle variation signal enhancement can vary by several orders of magnitude single batch, largely limiting reliable use practical...
Plasmonic Gap Nanostructures In article number 2006966, Jwa-Min Nam and co-workers review key concepts advances in synthesis, assembly, optical properties, sensing applications of plasmonic gap nanostructures. nanogaps produce largely enhanced signals from highly localized electromagnetic fields. Control exploration the structures characteristics nanogap open new possibilities for various including surface-enhanced Raman scattering, biosensing, bioimaging.
