Method of making an aromagraph comprising ectopic olfactory receptors

A method for making an Aromagraph, comprising the steps of:

• providing a plurality of biosensors wherein each biosensor comprises an ectopic Olfactory Receptor, a G protein subunit Gα, a G protein subunit Gβ, a G protein subunit Gγ, and a reporter, wherein binding of the ligand to the ectopic Olfactory Receptor sends a signal through the G protein subunits resulting in a signal from the reporter, wherein at least some of the biosensors have a different ectopic Olfactory Receptor, adding the ligand to the biosensors, detecting an increase for a reporter whereby binding of the ligand to the ectopic Olfactory Receptor is detected, and recording the reporter activity for the plurality of ectopic Olfactory Receptors.
