Single‐Carbon‐Atomic‐Resolution Detection of Odorant Molecules using a Human Olfactory Receptor‐based Bioelectronic Nose

Single-carbon-atomic-resolution detection of odorant molecules has been demonstrated using a human olfactory receptor-based bioelectric nose. Furthermore, since the human olfactory receptor is a G-protein-coupled receptor (GPCR), these sensor systems may be a new powerful platform for the development of new drugs and fragrances.
