Nanodisc-based bioelectronic nose. (a) Diagram of the sensor showing carbon nanotube transistors. The nanodisc-embedded TAAR13c was immobilized onto gold floating electrodes by using a half fragment antibody as a linker. (b) The response to the target ligand volatile organic compound (VOC) cadaverine is shown. The percent change in device conductance after exposure to spoiled food samples exhibiting higher responses following prolonged spoilage periods. Adapted with permission from Yang et al. 2017.
