Detection of simulated patters of lung cancer biomarkers using arrays of SWCNTs coated noncovalently with thin films of organic materials. (a) Patterns of responses of chemiresistive networks of SWCNTs coated with ten different organic materials (S1 to S10) when exposed to the representative VOCs for 10 min. (b) PCA score plots of the ten sensing arrays upon the exposure to “healthy” and “cancerous” mixtures of VOCs at (i) 80% RH, (ii) 10% RH, (iii) 1% RH, and (iv) 80% RH with preconcentration of VOCs of 50 times.
