One of the recently emerging topics in biotechnology is natural receptors including G protein-coupled receptors, ligand-gated ion channels, enzyme-linked receptors, and intracellular receptors, owing to their molecular specificity. These receptors, other than intracellular receptors, which are membrane proteins expressed on the cell membrane, can detect extracellular stimuli. Therefore, integration of conducting nanomaterials and natural receptors, as we called Receptonics, allows highly sensitive and selective responses toward target molecules such as cadaverine, geosmin, biocides and so on. Moreover, the receptonics can provide "False-Negative Zero" technologies in the field of virus detection. Based on their unique characteristics in the field of biosensors, the receptonics enable to provide next-generation diagnostics as NanoBio sensors.
