Rhodamine-anchored poly(norbornene) for fluorescent sensing of ATP

Efficient fluorescent recognition of ATP/GTP by a water-soluble bisquinolinium pyridine-2,6-dicarboxamide compound. Crystal structures, spectroscopic studies and interaction mode with DNA

“…Fluorescent recognition of ATP/GTP has been dominated by organic articial receptors containing arrays of hydrogen bond donors of NH/CH type or polycationic moieties as binding sites for the polyphosphate fragments. [14][15][16][17][18][19][20][21][22][23][24] Typically, these receptors show binding constants between 10 2 and 10 4 M −1 . 25,26 Consequently, they are suitable to recognize ATP/GTP in the millimolar concentration range, but not signicantly below.…”

Biogenic Polymer-Based Fluorescent Assemblies: Versatile Platforms for Ultrasensitive ATP Detection and Enzyme Assay

“…Polymer matrices can shield enclosed dyes from environmental factors like light, moisture, and oxygen, thereby enhancing the stability and shelf life of the sensors . The relatively hydrophobic microenvironment surrounding the dye molecules embedded within the polymer matrix fosters stronger intermolecular interactions with target analytes. , Additionally, the local concentration of dye molecules remains significantly higher than in the bulk solution phase, ensuring multipoint supramolecular interactions that result in enhanced sensitivity. , Furthermore, by reducing background fluorescence and minimizing signal interference, polymer–dye composites can boost the signal-to-noise ratio, leading to more accurate and reliable measurements. Moreover, due to the inherent competitive interactions, these composites can be tailored to respond exclusively to the presence of specific target molecules, thus improving selectivity in sensing applications. , The optical properties of polymer–dye composites, including fluorescence emission wavelengths and quantum yields, can be fine-tuned by selecting different dyes or polymers or by adjusting their relative ratios in the composite. , This adaptability allows for the customization of polymer–dye composite materials to be compatible with a wide range of analytes, making them versatile for various sensing applications.…”
