Silk-Protein-Based Nanoscale Color Filter Array and Its Security Applications

초록

영어

We present an innovative nanoscale color-filter array utilizing a metal-insulator-metal (MIM) resonator structure. The insulator layer is made of silk fibroin, with its thickness controlling the resonance frequency of the MIM cavity. Using grayscale electron-beam lithography (EBL), we achieved precise control over the silk fibroin thickness, enabling high-resolution variation. The resulting color filters demonstrated an impressive resolution of 80k dots per inch (DPI) while maintaining exceptional color purity.
