Thermal‐Assisted Multiscale Patterning of Nonplanar Colloidal Nanostructures for Multi‐Modal Anti‐Counterfeiting (Adv. Sci. 1/2024)

Multi-Modal Anti-Counterfeiting In article number 2305469, Tong Zhang, Dan Su, and co-workers introduce a thermal-assisted non-planar nanostructure transfer printing technique for the multiscale patterning of polystyrene nanospheres. With a resolution exceeding 2750 pixels per inch, the multiscale colloidal nanostructure patterns on a 4-inch wafer yield diverse optical images when subjected to various light excitations. This cover artwork highlights multi-modal optical anti-counterfeiting enabled by structural patterns at hierarchical length scales.
