AbstractDiagnosis and monitoring of pathologies, including cancers and infectious diseases, represent major challenges in the field of healthcare. New nanobiosensors carring olfactory receptors as sensitive elements provide effective and cheap detection devices allowing a quantitative and direct measurement without any labeling. This article presents the design principle and the biomedical applications of bioelectronic noses. The elaboration of these biosensors is detailed by describing the production of olfactory receptors, the methods for immobilization and for odor detection, as well as the contributions of miniaturization. Finally, examples of recent implementations are provided.
