Combining the fascinating electronic properties of Prussian blue analogues and the exceptional processing possibilities inherent in nanostructured oxide chemistry, photo-switchable Prussian blue nanoparticles have been successfully grown within the well-defined craters of a TiO2 nanoperforated monolayer. Each Prussian blue particle can potentially act as a single memory bit.
