Functional Lipid Vesicles Based on Artificial Electric-Taster Sensor

Abstract

We have demonstrated the functional lipid vesicles based on artificial electric-taste sensor capable of identifying NaCl, HCl, sucrose and quinine. It used the membrane modified gold electrode with neutral, positive, negative, hydrophilic vesicles. The discriminative character of our taste-sensors has been confirmed by evaluating them against four basic taste solutions using electrochemical method. Each taste sensor was exhibited variations in electric current response when exposed to the four basic taste solutions. The principle component analysis (PCA) on our sensor was clearly recognized against four basic tastes.
