Sensing Materials: Nanofibers Produced by Electrospinning and Solution Blow Spinning

In this book chapter we review recent advances on the use of electrospun and solution-blow spun nanofibers, which display remarkable features as high surface area to volume ratio, high porosity, mechanical flexibility and possibility of functionalization, in the design of chemoresistive, electrochemical, opto-chemical and electronic-tongue sensors. Emphasizes is given on the fabrication of nanofibers of varied size, shape as well as with distinct surface and bulk functionalization with active compounds to interact with analytes ranging from heavy metals, food contaminants, microorganism, volatile organic compounds, among others. Finally, future trends for nanofibers fabrication and application in sensors are also discussed.
