Geometrical Characterization of Polyethylene Oxide Nanofibers by Atom Force Microscope and Confocal Laser Scanning Microscope

The aim of our research is the development of a prototype of a bionanosensor which can detect pathogens in enclosed spaces, such as hospital, in real time [2]. We investigate the properties of polymers nanofibers as sensing elements of the biosensor. Hence, the geometrical, mechanical and electrical properties of the fibers are very important for the design of the sensor. The nanofibers are ideal as sensing element, because its high surface-to-volume radio, that assured a high sensitivity, and since the average size of a virus is approximately 100 nm [1].
