Langmuir and Langmuir-Blodgett films of odorant binding protein/amphiphile study for odorant biosensor
Résumé
We have investigated Langmuir and Langmuir-Blodgett films of odorant binding protein/amphiphile for elaboration of artificial olfactory system, namely odorant biosensor. Under optimised experimental conditions the mixed monolayer at air/water interface is very stable and has been transferred efficiently onto functionalised gold supports by SAMs. Electrochemical impedance spectroscopy and atomic force microscopy techniques were used to characterise mixed LB films for detecting one kind of corresponding odorant molecule isoamyl acetate.
