Nanofibers are extremely thin fibers with diameters in the nanometer range, typically between 1 and 100 nanometers. These tiny fibers have unique properties, such as high surface area and strength, making them useful in various applications. They can be made from different materials, including polymers and metals, and are often used in products like filters, textiles, and medical devices. One of the most exciting uses of nanofibers is in the field of medicine. For example, they can be used to create scaffolds for tissue engineering, helping to regenerate damaged tissues. Additionally, nanofibers can enhance the performance of face masks by improving filtration efficiency, making them valuable in protecting against airborne particles.
