Abstract
A light sensor comprises a nanostructure connectable to a source electrode and a drain electrode, and light sensitive moiety covalently attached to a surface of the nanostructure. The light sensitive moiety comprises a light sensitive molecule having an absorbance spectrum in a visible range. The light sensitive molecule is selected such that upon irradiation of the light sensor by light having a central wavelength within the absorbance spectrum, the sensitive molecule transfers or extracts an electron to or from the surface of the nanostructure.
