• Introduction

    A fiber that has a width of less than 1000 nanometers (1000 nm or 1 µm) is generally defined as a nanofiber. A nanoparticle is defined as a small group of atoms or molecules with a radius of less than 100 nanometers (100 nm).Particles on the nanoscale have a very high surface area to volume ratio, whereas this ratio is much lower for objects on the macroscopic scale.

    Nanofabrics are textiles engineered with small particles that give ordinary materials advantageous properties such as superhydrophobicity, odor and moisture elimination, increased elasticity and strength, and bacterial resistance. Depending on the desired property, a nanofabric is either constructed from nanoscopic fibers called nanofibers, or is formed by applying a solution containing nanoparticles to a regular fabric.

    Applications of nanofabrics have the potential to revolutionize textile manufacturing and areas of medicine such as drug delivery and tissue engineering.
