Nanowires also show other peculiar electrical properties due to their size. Unlike single wall carbon nanotubes, whose motion of electrons can fall under the regime of ballistic transport (meaning the electrons can travel freely from one electrode to the other), nanowire conductivity is strongly influenced by edge effects.
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.
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.

While being limited by the resolution of these methods, it allows a large degree of control over the resulting structures. In this manner devices such as nanowires, nanorods, and patterned nanostructures are fabricated from metallic thin films or etched semiconductor layers. For top-down approaches, increasing surface area to volume ratio ...
The nanowires are sensitive to detect trace biomarkers that diffuse into the IV line through blood which can monitor kidney or organ failure. These nanowires would allow for continuous biomarker measurement, which provides some benefits in terms of temporal sensitivity over traditional biomarker quantification assays such as ELISA.
They vary widely, however, due to highly localized regions of the nanowires where the effective cross-sectional area for superconducting current is reduced. [29] SNSPD devices have also demonstrated exceptionally low jitter – the uncertainty in the photon arrival time – as low as 3 picoseconds at visible wavelengths.
Inorganic nanomaterials, (e.g. quantum dots, [29] nanowires, and nanorods) because of their interesting optical and electrical properties, could be used in optoelectronics. [30] Furthermore, the optical and electronic properties of nanomaterials which depend on their size and shape can be tuned via synthetic techniques.
These nanowires form a mesh that absorbs up to twenty times its weight in hydrophobic liquids while rejecting water with its water repelling coating. Since the potassium manganese oxide is very stable even at high temperatures, the oil can be boiled off the nanowires and both the oil and the nanowires can then be reused.
