Journal ArticleDOI
Tuning Interior Nanogaps of Double-shelled Au/Ag Nanoboxes for Surface-Enhanced Raman Scattering
TL;DR: The SERS of the double-shelled nanoboxes increase significantly with the decrease of gap size, consistent with the theoretical prediction that smaller gap size induces larger localized electromagnetic enhancement.
Journal ArticleDOI
Plasmon-Enhanced Fluorescence in Coupled Nanostructures and Applications in DNA Detection
TL;DR: A systematic study on the influence of different factors on plasmon coupling-enhanced fluorescence, including shape and size of metal NPs, dye distribution, and separation distance, found Au@Ag NSs to give the largest fluorescence enhancement effect.
Journal ArticleDOI
High sensitivity molecule detection by plasmonic nanoantennas with selective binding at electromagnetic hotspots.
TL;DR: Both optical characterization using a dark field microscope and the FDTD simulation show that after the streptavidin binding, the signal increases with decreasing gap size, which is promising with respect to the future detection of single molecules.
Journal ArticleDOI
Mimicking optical activity for generating radially polarized light.
TL;DR: Using Poincaré sphere representation, it is shown that the polarization transformation of such a scheme is equivalent to that of a spirally varying optical activity and is capable of generating radially polarized light.
Journal ArticleDOI

TL;DR: The physical mechanism for the enhancement of absorption and scattering of light due to plasmonic Young's interference is revealed, which is explained through a redistribution of the Poynting vector field and the formation of near-field subwavelength optical vortices.
