Prototype of an integrated olfactory biosensor based on the electrochemical response properties of olfactory receptors

We have integrated all the developments carried out during the project in an olfactory biosensor prototype consisting of:
- A microtransducer consisting of a microelectrochemical cell.

- A single layer of nanosomes incorporating the “selected olfactory receptor” and immobilised through the mixed functionalisation technique developed.

- An electrochemical nanoscale amplification electronic circuit.

- An acquisition board plus a user-friendly interface for the data acquisition and processing.

- A liquid cell specifically designed for the nanobiosensor with liquid injection pumps for odorant injection.

In any case, even if not fully demonstrated, the developed set up theoretically satisfies the requeriments it should meet to work as a biosensor based on the electrical properties of olfactory receptors with sensibility down to a single nanosome, that was one of the main objectives of the project.
