Nanowires are extremely thin wires with diameters in the nanometer range, typically between 1 and 100 nanometers. They can be made from various materials, including metals, semiconductors, and insulators. Due to their small size, nanowires exhibit unique electrical, optical, and mechanical properties, making them useful in a variety of applications, such as sensors, transistors, and energy storage devices. These tiny structures can be produced using different methods, including chemical vapor deposition and electrospinning. Researchers are exploring their potential in fields like nanotechnology, electronics, and renewable energy, as nanowires can enhance the performance of devices and contribute to advancements in technology.
