Cancer detection : The development of a cost‐effective, portable and non‐invasive diagnostic tool for detecting cancer from exhaled breath requires sensors that discriminate well between polar and nonpolar volatile organic compounds in highly humid atmospheres. Here we show that a chemiresistive bilayer comprised of a dense cap layer of discotic hexa‐dodecyl‐hexa‐peri‐hexabenzocoronene derivatives (hereby, HBC‐C12) and a random network of carbon nanotubes (RN‐CNT) as underlayer layer could fulfill these requirements.
