<div>Normalized electrical resistance of both CNX-MWNT and CNX-MWNT-Ag sensor devices exposed to (a) ethanol, (b) acetone, and (c) chloroform at room temperature (25°C). The shadow areas are exposure cycles of the different gases, equivalent to 80 s. The dashed (solid) line corresponds to sensors based on CNX-MWNTs decorated with Ag nanoparticles (pure CNX-MWCNTs).</div>
