Abstract Inspired by the emerging potential of photoluminescent hydrogels, this work unlocks new avenues for advanced biosensing, bioimaging, and drug delivery applications. Carbon quantum dots (CDs) are deemed particularly promising among various optical dyes, enhancing polymeric networks with superior physical chemical properties. This study presents synthesis CDs derived from Prunella vulgaris , a natural plant resource, through single‐step hydrothermal process, followed their uniform integration into hydrogel matrices via an in situ free radical graft polymerization. The resulting CD‐integrated hydrogels exhibit multifunctionality biomedical applications, featuring diffusion‐controlled release mechanism, permit concurrent therapeutic agents, enabling real‐time monitoring over 32 h. In addition, these function as broad‐range pH sensor (pH 3–11), provide robust ultraviolet (UV) shielding, demonstrate nanozyme‐like peroxidase activity. Critically, biocompatibility tests confirm non‐cytotoxicity toward fibroblast cells, establishing candidates diverse These include wound dressings that monitor healing process detect infection sensing, promote nanozymatic activity, all while maintaining moist microenvironment. exceptional suitability smart delivery, effective UV‐blocking, innovative platforms vivo sensing bioimaging.
