The superconducting nanowire single-photon detector (SNSPD or SSPD) is a type of optical and near-infrared single-photon detector based on a current-biased superconducting nanowire. [1] It was first developed by scientists at Moscow State Pedagogical University and at the University of Rochester in 2001.
A nanowire is a nanostructure in the form of a wire with the diameter of the order of a nanometre (10 −9 m). More generally, ... and ethanol sensors. ...

Nanowire lasers can be grown site-selectively on Si/SOI wafers with conventional MBE techniques, allowing for pristine structural quality without defects. Nanowire lasers using the group-III nitride and ZnO materials systems have been demonstrated to emit in the visible and ultraviolet, however infrared at the 1.3–1.55 μm is important for telecommunication bands.

Schematic of silicon nanowire. Silicon nanowires, also referred to as SiNWs, are a type of semiconductor nanowire most often formed from a silicon precursor by etching of a solid or through catalyzed growth from a vapor or liquid phase. Such nanowires have promising applications in lithium-ion batteries, thermoelectrics and sensors.
Plasmonic nanolaser sensors have recently been demonstrated that can detect specific molecules in air and be used for optical biosensors. Molecules can modify the surface of metal nanoparticles and impact the surface recombination velocity of gain medium of a plasmonic nanolaser, which contributes to the sensing mechanism of plasmonic nanolasers.

In 2020, her research group introduced a method for manufacturing nanowire sensors by electrochemically depositing charge-transfer salt nanowire crystals on sensor substrates, demonstrating their gas sensing capabilities for detecting ammonia concentrations in the range of 1–100 ppm through electrical impedance measurements.
