En 中文
In the realm of modern cryptography and anti-counterfeiting, innovative approaches are crucial to encode sensitive information securely. Tailored responsive structural colors have garnered significant interest due to their feature-rich spectra and high sensitivity to external stimuli. However, high costs and complex processing involved in integrating the various delicate microstructures have impeded their widespread development. In this study, we present a straightforward multilevel chromatic encryption scheme utilizing direct-writing gradient-crosslinked microdomes. The solvent-responsive structural color of each microdome, arising from the synergistic effect of total internal reflections and interference, is adjusted independently across the entire visible region. Each microdome functions as a signal recording unit, enabling multilevel color variations through a solvent-dependent development step. This approach facilitates the encoding of enhanced information into a single pixel. To demonstrate the efficacy of our method for advanced applications, we have prepared a collection of solvent-dependent multilevel codes for algorithm cryptography, showcasing its potential for high-level anti-counterfeiting and high-density optical data storage.
