BIOMEDICAL APPLICATIONS OF ELECTROSPUN NANOFIBERS

Abstract

Electrospun technology is a simple and flexible method for preparation of nanofiber materials with unique physical and chemical properties. The nanofiber diameter is adjustable from several nanometers to few microns during the preparation. Electrospun nanofiber materials are easy to be assembled into different shapes of three-dimensional structures. These materials exhibit high porosity and surface area and can simulate the network structures of collagen fibers in a natural extracellular matrix, thereby providing a growth microenvironment for tissue cells. Electrospun nanofibers therefore have extensive application prospects in the biomedicine field, including in aerospace, filtration, biomedical applications, and biotechnology. Nanotechnology has the potential to revolutionize many fields, such as surface microscopy, silicon fabrication, biochemistry, molecular biology, physical chemistry, and computational engineering, while the advent of nanofibers has increased the understanding of nanotechnology among academia, industry, and the general public. This paper mainly introduces the application of nanofiber materials in tissue engineering, drug release, wound dressing, and other biomedicine fields.
