We propose a nanosensor with a biological active part able to identify specific odorants. The biological part should be constituted by olfactory receptors pertaining to the G protein-coupled receptors, the most efficient natural sensors for odorant discrimination. Modeling, design, and experiments performed for proving the concept are reported and discussed.

Sensory receptors in biological systems are an essential part of natural organisms to perceive, understand and adapt their environment evaluate internal state. They interlinked with the senses living important tool for survival evolution species. Researchers have implemented biomimetic receptor approach into development artificial sensors, attempt mimic sensory transduction organisms, like self...
