Porphyrin-Based Nanostructures for Sensing Applications
Figure 6
(a) Differential CSPT absorbances measured exposing the nanotube layers to the different vapors and gases. (b) Plot of the first two principal components calculated from the fingerprints shown in (a). Label data points indicate the compounds: tea: triethylamine, NOx, eta: ethanol, ace: acetic acid, and tol: toluene.
