Advances in the production, immobilization, and electrical characterization of olfactory receptors for olfactory nanobiosensor development

The animal olfactory system represents the gold standard of olfactory biosensors with its capability to identify and discriminate thousands of odorant compounds. In order to mimic the performances of natural olfactory sensors it is necessary to develop methods and techniques for the production, immobilization and electrical characterization of olfactory receptors. We review in this paper some of the advances we obtained in these fields.
