Abstract Cephalopods use stretchy skin and dynamic color‐tuning organs for visual communication camouflage. Inspired by these natural mechanisms, a fluorescent biomaterial deformation‐induced illumination optical is proposed. This the first report of 3D printed soft biomaterials infused with carbon dots hydrothermally derived from chitosan benzalkonium chloride. These exhibit comprehensive array properties, including significant uniaxial stretching, near‐instantaneous response to tactile stimuli pH, UV resistance, antibacterial, antioxidant, noncytotoxicity, highlighting their potential as mechano‐optical materials biomedical applications. The hydrogel's durability evaluated cyclic folding, rolling, twisting tests ensure its integrity good signal‐to‐noise ratio. diffusion mechanism determined water imbibition kinetics, network parameters, time‐dependent breathing. Overcoming common limitations short lifespans complex manufacturing processes in existing hybrids, this work demonstrates straightforward method produce durable, energy‐independent, hydrogel. Combined investigations, molecular modeling used understand interactions hydrogel components.

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.

Dental diseases, including conditions affecting oral structures, have become more common due to unhealthy lifestyle choices. Traditional antibiotic treatments face challenges related the development of resistance in bacteria. Photodynamic antibacterial chemotherapy is emerging as a promising alternative using photosensitizers generate reactive oxygen species upon exposure light. This article examines photosensitizer Rose Bengal (RB) immobilized hyaluronic acid (HA) for prolonged action. The RB-HA conjugate demonstrated molar ratio approximately three RB residues each ten units HA. exhibited high singlet quantum yield (ΔΦ = 0.90), suggesting its efficacy photodynamic treatment. A photostability analysis revealed slower photobleaching RB-HA, which essential application. Under visible light and ultrasonic treatment, effective activity against Gram-positive
