- Abstract
- The aim of the present study is to combine a bio-inspired nanofibrous artificial epithelium to the electronic
nose (e-nose) principles. The sensing device set up was an electronic nose consisting of an array of 9 microchemoresistors
(CrAu, 3×3) coated with electrospun nanofibrous structures. These were comprised of
doped polyemeraldine base blended with 3 different polymers: polyethylene oxide, polyvinilpyrrolidone
and polystyrene, which acted as carriers for the conducting polymer and were the major responsible of
the features of each fibrous overlay (electrical parameters, selectivity and sensitivity ranges). The two
sensing strategies here adopted and compared consisted in the use of 2 different textural coatings: a
single- and a double-overlay, where the double-overlay resulting from overdeposition of 2 different
polymer blends. Such e-nose included a plurality of nanofibres whose electrical parameters were at the
same time depending on each polymer exposure to analytes (NO2, NH3) and on the spatial distribution of
the interlacing fibres. The morphology of the coating arrangements of this novel e-nose was investigated
by scanning electron microscopy (SEM) and its sensor responses were processed by multicomponent
data analyses (PCA and PLS) reporting encouraging results for detection and recognition of analytes at
ppb levels. (literal)
