In article number 1804916 , Ximin He and co‐workers present a universal (bio)chemical sensing platform based on hydrogel interferometry. The stimuli‐responsive gel thin film presents different colors, revealing rich environmental metrics. The unique local concentration effect and signal amplification effect lead to ultrahigh sensitivity up to the femtomol level. The high selectivity against interfering molecules grants this platform great promise in broad practical applications.
