Abstract
A process of extracting date fruit melanin from the date fruit for use in electrical application comprising providing a date fruit puree, mixing the puree with an alkaline solution to solubilize melanin, followed by acid precipitation of melanin using an inorganic acid. The melanin obtained finds its use as an electrically conductive portion in an electronic component of devices comprising of a sensor, a photovoltaic cell and/or bioelectronic device.

An electronic component comprising an electrically conductive portion, the electrically conductive portion comprising one or more electrodes and a date fruit derived melanin polymer, wherein the date fruit derived melanin polymer is in connection with the one or more electrodes and exhibits a higher electrical conductivity—in the absence of incident illumination than under incident illumination, wherein the incident illumination is provided by a light source emitting within an ultraviolet-visible spectrum and wherein the electrical conductivity is measured for a date fruit derived polymer at above zero volts at 10 Hz using a current-voltage measurement method;
- and
- wherein the date fruit derived melanin polymer is derived from a method comprising:
- providing a date fruit puree;
- and
- alkaline extraction of crude melanin.
A method of forming an electrical component comprising an electrically conductive portion that comprises a date fruit derived melanin polymer, wherein the method comprises:
- extracting date fruit derived melanin polymer according to a method comprising:
- providing a date fruit puree;
- and
- alkaline extraction of crude melanin;
- forming the electrically conductive portion by incorporating the date fruit derived melanin polymer such that it is in connection with one or more electrodes, wherein the date fruit derived melanin polymer exhibits a higher electrical conductivity in the absence of incident illumination than under incident illumination, wherein the incident illumination is provided by a light source emitting within an ultraviolet-visible spectrum and wherein the electrical conductivity is measured for a date fruit derived polymer at above zero volts at 10 Hz using a current-voltage measurement method.
