Abstract :

We report a dose-dependent detection of androstenone in solution, as one of boar taint compounds, based on related OR 7D4 olfactory receptors immobilized on gold electrodethrough their 6-His tag and NTA-copper complex (Scheme 1), as visualized through fluorescence microscopy. Square wave voltammetry (SWV) is the method used to monitor the electrochemical transduction process. The relative variation of current Cu(I)-Cu(II) peak increases linearly versus log (concentration of androstenone) from 10-14M to 10-4M, in buffer solution. Negative tests were performed, using an unrelated odorant, helional, itself related a ligand. Cross-selectivity was also tested after immobilization.
