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 the potential of nanowires in fields like nanotechnology, electronics, and renewable energy, as they can enhance the performance of devices while reducing their size and weight.
