Cell-based sensors using olfactory receptors have attracted attention because of their high sensitivity and selectivity. A challenge is efficient partition of gaseous samples to the aqueous solution where the cell-based sensors reside. In this paper, we developed a device with a gas-flow channel, which allowed inflow of gaseous odorants over a well filled with aqueous solution. We considered that shear stress induced by the gas-flow at the gas-liquid interface initiate convectional mixing inside liquid and in turn, promotes partitioning of gaseous odorants into the solution. Solubility of a gaseous odorant was experimentally found to increase with the mixing strength. We further demonstrated efficient detection of a gaseous odorant using the sensor cells with the developed gas-flow device.
