Abstract

Nanotechnology is an emergent field of research and innovation applied to nanoelectronics, nanomaterials, nanobiology, nanomedicine, among other areas. Particularly in medicine it has been used to improve the disease diagnosis through novel instrumentation as well as the treatment efficacy through the encapsulation and controlled release of bioactive compounds. Overall, nanotechnology can provide novel tools and techniques to biomedical research, namely in proteomics, genetics and regenerative medicine. Polymer nanofibers are one of the nanostructures that have been used in nanomedicine, especially those fabricated by electrospinning. The development of drug delivery systems, wound dressing materials, tissue regeneration and disease diagnosis are the most representative examples about the use of electrospun nanofibers. Their use in medical microbiology has mostly contributed to an improvement in the treatment of microbial infections through the increase of response capacity of active pharmaceutical ingredients but also into the reduction of side effects. In this chapter, a comprehensive overview about the manufacturing techniques and the most common polymers used for nanofibers production is discussed. The relation between the usefulness of these nanofibers with their composition, their size, and orientation is pointed out. Their medical applications on microbiology, namely the local administration of antibiotic drugs in infected areas, the development of wound dressing materials to improve the healing process and the possibility to raise or replace biological functions without organ transplantation by the use of artificial materials were analysed covering the developments accomplished over the last 10 years. It is noticed a lack of information about the formation of biofilms on the surface of nanofibrous scaffolds. Moreover, more studies must be done considering the nanoscale morphology and the type of polymer used, which seems to be crucial to prevent infections by microorganisms across medical applications.
