Functionalized Nanofibers - Nanotechnology

What are Functionalized Nanofibers?

Functionalized nanofibers are specialized nanomaterials that have been engineered at the molecular level to exhibit specific properties by adding various functional groups to their surfaces. These modifications enhance the fibers' chemical, physical, and biological characteristics, making them suitable for a wide range of applications in biomedical, environmental, and industrial fields.

How are Functionalized Nanofibers Created?

Functionalized nanofibers are typically produced using techniques such as electrospinning, self-assembly, and template synthesis. During these processes, functional agents like polymers, metal nanoparticles, or biomolecules are incorporated into the nanofibers. The functionalization can occur either during the fiber fabrication or through post-synthesis modifications such as chemical grafting.
