Photo-responsive electrospun polymer nanofibers: Mechanisms, properties, and applications

Stimulus Modulation of White Light Emission in Colloidal Polymer Nanoparticles by Fluorescence Resonance Energy Transfer for Temperature Sensing and Security Encryption

“…These changes serve as signals indicating the binding of guest species to the acceptor. , FRET was first integrated in small-molecule systems mainly for detection applications, which had some pros like high FRET efficiency, simplicity, and ease of preparation. However, the drawbacks include low solubility, especially in water, insufficient biocompatibility, poor structural stability, and difficulties in further functionalization, hindering their practical use. , To address these shortcomings, FRET-based smart polymer chemosensors were introduced, offering high signal amplifications, the ability to enter different recognition groups, increased analyte binding ability, high selectivity and sensitivity, and quick response with potential applications in sensors of gas, temperature, pH, humidity, and also ions through their tunable properties. − A recent trend in enhancing document and brand security involves using advanced anticounterfeiting materials based on smart polymers, which include fluorescent and photochromic substances, such as inorganic paints, organic dyes, rare earth metal complexes, polymer dots, particles, and supramolecular structures. − WLE materials, with their special coordination, combining fluorescent compounds and smart polymers, could be a strong candidate for anticounterfeiting technology. , However, very few studies on white light-emitting paper (WLEP), white light-emitting silk (WLES), and white light-emitting ink (WLEI) have recently been performed.…”
