With the emergence of nanotechnology, researchers have become interested in studying the uniqueproperties of nanoscale materials. Nanofibers are attractive in the biomedical field for several reasons.First, surface area on nanofibers is much higher compared to bulk materials, which allows for enhancedadhesion of cells, proteins, and drugs. Second, nanofibers can be fabricated into sophisticated macroscalestructures. The ability to fabricate nanofibers allows renewed efforts in developing hierarchicalstructures that mimic those in animals and humans. This article describes various fabrication methodsof nanofibers including phase separation, self assembly and electrospinning. Electrospinning, anelectrostatic fiber fabrication technique, has evinced more interest and attention in recent years due toits versatility and potential for applications in diverse fields. In this review article we have focused ongeometrical, chemical and mechanical characterizations of nanofibers and its application in biomedicalfield. The notable applications are in the fields of tissue engineering, biosensors, wound dressings, drugdelivery and cosmetic technology.
