Polypyrrole nanotubes conjugated with human olfactory receptors: high-performance transducers for FET-type bioelectronic noses.
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.
