This tunable holographic sensor offers interrogation and a reporting transducer as well as an analyte‐responsive hydrogel, rendering it label‐free and reusable. A single 6 ns laser pulse is used to fabricate holographic sensors consisting of silver nanoparticles arranged periodically within a polymer film. The tunability of the sensor is demonstrated through pH sensing of artificial urine and validated through computational modeling.
