Nanowires are extremely thin, wire-like structures with diameters on the nanoscale, typically ranging from 1 to 100 nanometers. They exhibit unique electrical, optical, and mechanical properties due to their high surface-to-volume ratio and quantum effects. Applications of nanowires span various fields, including electronics, where they are used in sensors and transistors for improved performance; energy, as components in solar cells and batteries for enhanced efficiency; and biomedical technology, facilitating drug delivery and imaging. Their versatility and innovative characteristics position nanowires as key components in next-generation nanotechnology and materials science.
