Abstract
A method of inferring the existence of light by means of a measurement of the electrical characteristics of a nanotube bound to a dye first of all involves bringing a nanotube derivatized with a dye into contact with two conductor tracks. An electrical parameter of the nanotube is then measured via the two conductor tracks without exposure to light. Then the dye bound to the nanotube is irradiated, and the electrical parameter of the nanotube is then measured via the two conductor tracks with exposure to light. The difference between the value of the electrical parameter measured without exposure to light and the corresponding parameter measured with exposure to light is then established. Finally it is inferred, as a function of the difference established, whether light is present.
