Description

<p>We developed a cell-based wireless odorant sensor using a chip LED and a chip photo diode (Fig.1). Cells are expressing olfactory receptors (ORs), and they emit fluorescence when odorants are added. The measured fluorescence is transmitted to PC by wireless communication. We optimized the device by changing types of LED and filter. We also changed brightness and exposure time to maximize the S/N ratio. Then we tried to detect change in fluorescence intensity after adding odorants. The device responded to addition of buffer with odorants, whereas it returned no response when buffer without odorants is added. This device would be useful for on-site odorant detection.</p>
