N2 - A lot of efforts have been given to develop artificial olfactory sensor, called 'electronic nose', based on arrays of semiconductor devices for the application in the field of food industry, disease diagnostics, anti-terrorism [1]. However, the capability of the electronic nose is still, in many ways, inferior to that of the human olfactory system in terms of selectivity and sensitivity [2]. Herein, we demonstrate high performance bioelectronic nose by the integration of human olfactory receptor and graphene-FET sensor platform. The micropatterned graphene-FET sensor was fabricated using photolithography process and functionalized with hOR2AG1 was produced using E. coli. The bioelectronic nose was operated as liquid ion gated FET system and exhibited high sensitivity upon the stimulation of odorant with single-carbon atomic resolution. in food and beverage industries.
