Accordion-like plasmonic silver nanorod array exhibiting multiple electromagnetic responses

Array of silver nanocylinders: plasmonic properties, the effects of a close silver layer and fluorescence enhancement

Surface-enhanced spectroscopy is a branch of techniques that enhance light emission from molecules at nanoscale proximity to plasmonic structures. Examples of SES include surface-enhanced fluorescence (SEF), surface-enhanced phosphorescence, surface-enhanced Raman spectroscopy (SERS), surface-enhanced infrared absorption and surface-enhanced chemiluminescence. We are interested in applying plas...

Reflective plasmonic color filters based on lithographically patterned silver nanorod arrays.

We demonstrate reflection-mode plasmonic color filters based on lithographically patterned silver nanorods with ultrasmall inter-rod gaps. Fine and effective tuning of the plasmon resonance is shown by varying array periodicities. We determine the dependence of reflected intensity on diameter/periodicity ratio and then develop reflective plasmonic color filters using dense nanorod arrays. Exper...

Electromagnetic enhancement of ordered silver nanorod arrays evaluated by discrete dipole approximation

The enhancement factor (EF) of surface-enhanced Raman scattering (SERS) from two-dimensional (2D) hexagonal silver nanorod (AgNR) arrays were investigated in terms of electromagnetic (EM) mechanism by using the discrete dipole approximation (DDA) method. The dependence of EF on several parameters, i.e., structure, length, excitation wavelength, incident angle and polarization, and gap size has ...

Label-free SERS detection of microRNA based on affinity for an unmodified silver nanorod array substrate.

A silver nanorod array has been used for the intrinsic SERS detection of microRNAs based on different binding affinities of ssRNA, thiolated ssDNA, and the RNA:DNA duplex, eliminating the need for a labelling step.
