Achieving planar plasmonic subwavelength resolution using alternately arranged insulator-metal and insulator-insulator-metal composite structures

TL;DR: This work develops and analyzes a planar subwavelength device with the ability of one-dimensional resolution at visible frequencies that is based on alternately arranged insulator-metal-IIM composite structures and has potential applications in multi-functional material, real-time super-resolution imaging, and high-density photonic components.
Journal ArticleDOI

Modified Long Wavelength Approximation for the Optical Response of a Graded-Index Plasmonic Nanoparticle

TL;DR: In this paper, the optical response of graded-index spherical metallic nanoparticles is studied in the modified long wavelength approximation with electrodynamic effects accounted for to the lowest order of the inverse of the wavelength.
Journal ArticleDOI

Modulating cell-uptake behavior of Au-based nanomaterials via quantitative biomolecule modification

TL;DR: The cell uptake analysis indicates that the high-degree Tf modified Au–Fe3O4 nanoparticles have rapid-targeting ability and easy internalization toward cancer cell, compared to low-degree ones, implying that the efficiency of cell targeting can be improved or lowered by modulating Tf modification.
Proceedings ArticleDOI

Coherent Excitation-Selective Spectroscopy in Planar Metamaterials

TL;DR: In this article, the electric and magnetic resonances of metamaterials can be separately switched off and on by positioning the metammaterials along a standing wave, while both resonances are present in travelling-wave spectra.
Journal ArticleDOI

Implementation of a short‐tip tapping‐mode tuning fork near‐field scanning optical microscope

TL;DR: The experimental results show that this new short‐tip tapping‐mode tuning fork scheme provides a stable and high Q factor at the tapping frequency of the tuning fork and will be very helpful when long optical fibre probes have to be used in an experiment.
