Biocompatible silk random lasing is obtained by nanostructuring silk proteins into a disordered porous matrix via a self‐assembly technique. Lasing action is revealed by spectral narrowing and threshold behavior, and it is sensitive to pH variations in the aqueous environment. Silk random lasing provides a versatile biocompatible system, opening up opportunities for biophotonic applications and biosensing.
