Get a whiff of this : Human olfactory receptor (hOR)‐conjugated polypyrrole (PPy) nanotubes were integrated into the field‐effect transistor (FET) sensor platform for the fabrication of high‐performance bioelectronic noses (see picture, S=source, D=drain). The device can translate and amplify hOR–odorant interaction into a detectable signal, and it showed highly sensitive and specific responses toward a target odorant.
