摘要:
A method which serves for writing a three-dimensional arrangement of data bits to a solid-state body comprises the steps of selecting a protein having fluorescence properties that can be altered by means of an optical write signal; providing the solid-state body made from the protein, the protein being present in the solid-state body in crystalline form; setting a spatial distribution which corresponds to the three-dimensional arrangement of data bits of the fluorescence properties of the protein of the solid-state body by means of the optical write signal.
