Conspectus Nonlinear optics is limited by the weak nonlinear response of available
materials, a problem that is generally circumvented by relying on macroscopic structures in …

Near-field coupled plasmonic systems generally achieve plasmonically induced
transparency (PIT) using only one-way bright–dark mode coupling. However, it is …

Graphene nanoribbons (GNRs)—narrow stripes of graphene—have emerged as promising
building blocks for nanoelectronic devices. Recent advances in bottom-up synthesis have …

Armchair graphene nanoribbons (AGNRs) with a width of N= 3p+ 2 are theoretically
predicted to be metallic or half-metallic with a very small bandgap. The narrowest AGNR of …

Two-dimensional electron systems subjected to a perpendicular magnetic field absorb
electromagnetic radiation via cyclotron resonance (CR). Here we report a qualitative …

A label-free sensing strategy employing aptamers, SYBR Gold, and exonuclease I (Exo I) for
ochratoxin A (OTA) detection was designed. In the presence of target molecules (OTA), the …

The ability of graphene to support long-lived, electrically tunable plasmons that interact
strongly with light, combined with its highly nonlinear optical response, has generated great …

The ability to control the interaction of light and matter at the nanoscale is at the heart of the
field of nanophotonics. This subdiffractional confinement of light can be achieved through …

Ochratoxin A (OTA), is one of the most commonly found mycotoxins in food. It is primarily
produced by Aspergillus ochraceus and Penicillium verrucosum. OTA can causes serious …

Topological optical states exhibit unique immunity to defects, rendering them ideal for
photonic applications. A powerful class of such states is based on time-reversal symmetry …
