Information storage comprising: a storage element with a nanoparticle arrangement including a plurality of nanoparticles and a support material surrounding the nanoparticles; and a structured electrode; characterized in that the storage element is configured to: generate, in a first operating state, a regionally selective electric field in the nanoparticle arrangement by means of the structured electrode contacting a subregion of the support material, so that the nanoparticles which are detected by the regionally selective electric field and which are located in an extension of the subregion extending into the support material are selectively supplied with charge carriers with increased probability compared to nanoparticles outside this extension of the subregion, and, terminate, in a second operating state, the generation of the regionally selective electric field, wherein the nanoparticle arrangement largely prevents a discharge of the supplied charge carriers from the nanoparticles after termination and wherein the supplied charge carriers reduce a fluorescence intensity of the nanoparticles to which the electric charge carriers were selectively supplied in regions during the generation of the electric field, so that by optical excitation of the nanoparticle arrangement said subregion can be determined in which the electric charge carriers were selectively supplied in regions to the nanoparticles during the first operating state. a storage element with a nanoparticle arrangement including a plurality of nanoparticles and a support material surrounding the nanoparticles; and a structured electrode; characterized in that the storage element is configured to: generate, in a first operating state, a regionally selective electric field in the nanoparticle arrangement by means of the structured electrode contacting a subregion of the support material, so that the nanoparticles which are detected by the regionally selective electric field and which are located in an extension of the subregion extending into the support material are selectively supplied with charge carriers with increased probability compared to nanoparticles outside this extension of the subregion, and, terminate, in a second operating state, the generation of the regionally selective electric field, wherein the nanoparticle arrangement largely prevents a discharge of the supplied charge carriers from the nanoparticles after termination and wherein the supplied charge carriers reduce a fluorescence intensity of the nanoparticles to which the electric charge carriers were selectively supplied in regions during the generation of the electric field, so that by optical excitation of the nanoparticle arrangement said subregion can be determined in which the electric charge carriers were selectively supplied in regions to the nanoparticles during the first operating state. generate, in a first operating state, a regionally selective electric field in the nanoparticle arrangement by means of the structured electrode contacting a subregion of the support material, so that the nanoparticles which are detected by the regionally selective electric field and which are located in an extension of the subregion extending into the support material are selectively supplied with charge carriers with increased probability compared to nanoparticles outside this extension of the subregion, and, terminate, in a second operating state, the generation of the regionally selective electric field, wherein the nanoparticle arrangement largely prevents a discharge of the supplied charge carriers from the nanoparticles after termination and wherein the supplied charge carriers reduce a fluorescence intensity of the nanoparticles to which the electric charge carriers were selectively supplied in regions during the generation of the electric field, so that by optical excitation of the nanoparticle arrangement said subregion can be determined in which the electric charge carriers were selectively supplied in regions to the nanoparticles during the first operating state.
