Ultrasensitive detection of miRNA with an antimonene-based surface plasmon resonance sensor
Nature Communications, 2019 MicroRNA exhibits differential expression levels in cancer and can affect cellular transformation, carcinogenesis and metastasis. Although fluorescence techniques using dye molecule labels have been studied, label-free molecular-level quantification of ...

Strong coupling between surface plasmon polaritons and emitters: a review [PDF]
Reports on progress in physics. Physical Society, 2014 In this review we look at the concepts and state-of-the-art concerning the strong coupling of surface plasmon-polariton modes to states associated with quantum emitters such as excitons in J-aggregates, dye molecules and quantum dots.

Propagation of surface plasmons on plasmonic Bragg gratings [PDF]
Journal of Applied Physics, 2019 We use coupled-mode theory to describe the scattering of a surface-plasmon polariton (SPP) from a square-wave grating (Bragg grating) of finite extension written on the surface of either a metal-dielectric interface or a dielectric-dielectric interface covered with a patterned graphene sheet.

Optics Express, 2007 Employing an interferometric cavity ring-down technique we study the launching, propagation and reflection of surface plasmons on a smooth gold-air interface that is intersected by two parallel, sub-wavelength wide slits. Inside the low-finesse optical cavity defined by these slits the surface plasmon is observed to make multiple bounces.
