Then they measured the capacitance (the ability to hold an electric charge) of 4, 000 different positions to pinpoint the ideal mixture.

ECONOMIST: Combinatorial chemistry

Each bead is doped with a mixture of chemicals that become electrically charged in response to odour molecules and that charge alters the colour of the dye.
