Over the years, ground and surface water has been reported to be contaminated with phosphates. These phosphates are known to cause various diseases and if present in excess can lead to eutrophication. The known silane chemistry has not been thoroughly investigated for the sensing of anions. In the current study four new triazole based silanes have been prepared by the renowned Click Chemistry for the selective and sensitive detection of dihydrogen phosphate. The synthesized compounds were well characterized by various spectroscopic techniques and their absorptive and emissive responses were investigated for the recognition of dihydrogen phosphate ions. The binding ratio between triazole based silane chemosensor and dihydrogen phosphate has been discovered from Job's plot and was also confirmed by non‐linear fitting method. The value of association constant was found to be 571.18 M−1. The limit of detection (LOD) and limit of quantitation (LOQ) were calculated by fluorescence spectroscopy. The results obtained clearly illustrated that triazole based silane could be used as a potent chemosensor for selective and sensitive recognition of dihydrogen phosphate. Further, the possible binding site of chemosensor for dihydrogen phosphate has been identified from 1H NMR studies and DFT calculations. At last real sample analysis was performed to check the practical applicability of chemosensor.

“…In short, ratiometric fluorescence sensors have received increasing research attention due to their simple operation, safety, good stability, and suitability for high-throughput screening applications [ 26 ]. In the past few years, the ratiometric fluorescent sensors have been extensively used in the detection of diverse analytes including metal ions [ 27 , 28 , 29 ], anions [ 30 , 31 ], organic pollutants [ 32 ], and biomacromolecules [ 33 ]. However, a smartphone-based ratiometric fluorescent sensor for the detection of Ca 2+ content in bovine serum, to the best of our knowledge, has not been developed.…”

Hypocalcemia is a disease that adversely affects the production and reproduction of dairy cows. A portable device for rapid bovine blood calcium sensing has been growing in demand. Herein, we report a smartphone-based ratiometric fluorescence probe (SRFP) platform as a new way to detect and quantify calcium ions (Ca2+) in blood serum. Specifically, we employed a cost-effective and portable smartphone-based platform coupled with customized software that evaluates the response of Ca2+ ions to ratiometric fluorescence probe in bovine serum. The platform consists of a three-dimensional (3D) printed housing and low-cost optical components that excite fluorescent probe and selectively transmit fluorescence emissions to smartphones. The customized software is equipped with a calibration model to quantify the acquired fluorescence images and quantify the concentration of Ca2+ ions. The ratio of the green channel to the red channel bears a highly reproducible relationship with Ca2+ ions concentration from 10 μM to 40 μM in bovine serum. Our detection system has a limit of detection (LOD) of 1.8 μM in bovine serum samples and the recoveries of real samples ranged from 92.8% to 110.1%, with relative standard deviation (RSD) ranging from 1.72% to 4.89%. The low-cost SRFP platform has the potential to enable campesino to rapidly detect Ca2+ ions content in bovine serum on-demand in any environmental setting.
