Therefore, efficient and accurate detection of excessive inorganic ions in water is urgently needed. Using an in situ encapsulation method under solvothermal conditions, we develop a series of triple-emission fluorescent sensors, C6&amp;RhB@UiO-66-Ph (C&amp;R@U), by encapsulating green-emitting Coumarin 6 (C6) and red-emitting Rhodamine B (RhB) into a blue-emitting UiO-66-Ph MOF with 1,4-H₂NDC as the ligand. Among them, C&amp;R@U3 exhibits white-light emission with a CIE coordinate of (0.32, 0.32) and is used for the detection of Fe³⁺ ions and Cr₂O₇²⁻ ions in water. When the C&amp;R@U3 fluorescent probe interacts with target ions, the three emission peaks of the probe are quenched due to the resonance energy transfer effect, resulting in significant shifts in its CIE coordinates compared to other ions. The fluorescence intensity of the C&amp;R@U3 probe demonstrates excellent linearity with Fe³⁺ ion concentrations (0–0.6 mM) and Cr₂O₇²⁻ ion concentrations (0–0.1 mM), with detection limits of 0.71 μM and 16.9 nM, respectively. Experiments with real-world water samples and portable fluorescence test papers validate the practical applicability of C&amp;R@U3, revealing its great potential in on-site inorganic ion detection.

Modern dietary habits, lack of awareness, and delays in early detection are major contributing factors to the global spread of this issue. This work reports the promising findings for diagnostic accuracy of oral cancer in pre-malignant stages by analyzing surface enhanced Raman spectroscopy (SERS) profiles of different stages of oral cancer combined with multivariate analysis. Using 99 clinical samples from which 39 samples were from malignant stage, 28 from pre-malignant and 32 from healthy controls, SERS analysis was carried out by employing label-free silver nanorods as SERS substrates. The SERS spectra of malignant and pre-malignant samples manifest distinct peaks associated with varying concentrations of inorganic metabolites and proteins. Primarily, the elevated level of thiocyanate dominates the SERS spectra in malignant samples while antioxidants like uric acid, xanthine and hypoxanthine’s are the key elements in the pre-malignant samples. A ratio-metric analysis of 2130 and 1435 cm⁻¹ peak revealed that the pre-malignant lesions consistently lie between 2 and 3, whereas malignant samples have ratio greater than 3 due to higher intensity of thiocyanate peak. The multivariate analysis successfully separates between oral cancer positive and negative samples with a sensitivity and specificity of 93.5 and 92.7 % respectively.
