Multimodal water-soluble luminescent sensors based on hybrid nanostructures for simultaneous temperature and pH measurement

The modern development of analytical methods in the field of temperature and pH detection in various media, including biological ones, is associated with the development of luminescent sensors. The indisputable advantage of these sensors is their low invasiveness, remoteness, and the ability to perform intracellular measurements. Moreover, the luminescent properties of such sensors often depend on several environmental parameters: temperature, acidity, presence of active centers, etc. Such a complex dependence can either be an obstacle to the creation of a luminescent sensor due to the uncertainty of the determined values or form the basis for the creation of multimodal sensors for simultaneous registration of several parameters. Water-soluble luminescent molecular plasmon nanostructures based on AuAg core, SiO2 shell and tetra-aminoporphyrin are being developed as a multimodal luminescent sensor for simultaneous precision measurement of pH and temperature. The solubility in water makes these sensors promising in measuring intracellular parameters.
