Nanofibers are typically composed of polymers, carbon, or ceramic materials, and are characterized by their ultrafine diameters, often ranging from a few nanometers to hundreds of nanometers. These fibers can be produced using various fabrication techniques, including electrospinning, template synthesis, and self-assembly. Electrospinning, the most widely used method, involves the use of electric fields to draw out nanofibers from a polymer solution or melt, resulting in a high aspect ratio structure.
Nanofiber have sparked considerable excitement in the healthcare industry due to their exceptional properties. They possess a high surface-to-volume ratio, allowing for enhanced interactions with biological systems. Nanofiber-based wound dressings promote faster healing by creating a moist environment conducive to cell growth and reducing the risk of infection. Furthermore, nanofibers can be engineered to mimic the structure of native tissues, enabling their use in tissue engineering and regenerative medicine. Scaffold constructs made of nanofibers provide a three-dimensional framework for cell attachment and growth, facilitating the regeneration of damaged tissues and organs.
