The structural color of 1D photonic crystals modified with silver nanoparticles is a function of the silver‐loading state, which translates into an optically encoded silver‐release profile. Owing to their distinct silver‐uptake properties, clay–TiO 2 Bragg stacks (see image) thus show potential for the detection of antimicrobial activity based on a label‐free optical read‐out system.
