Spectrophotometric, fluorimetric and electrochemical selective pyrophosphate/ATP sensing based on the dimethyltin(IV)-tiron system

Heavy metal‐free electrochemical detection of pyrophosphate ions by Nafion/carbon dots decorated screen printed carbon electrodes

“…[16] Therefore, developing an effective receptor system for selective PPi detection is very important for the early-stage detection of these diseases. Considering the importance of PPi recognition, several methods such as fluorescence spectroscopy, [12,[17][18][19] surface-enhanced Raman scattering, [20] colorimetric sensing, [21][22][23] chemiluminescence, [24] electrochemical analysis, [25,26] and dark-field microscopy [27] have been developed. These methods are generally based on the complexation of PPi with metal ions, such as Al(III), [28,29] Fe(III), [23,[30][31][32][33] Ce(III), [34] Ca(II), [21] Zn(II), [35] Pb(II), [36,37] and Cu(II).…”

Microwave-assisted synthesis of green fluorescent copper nanoclusters: a novel approach for sensing of hydroxyl radicals and pyrophosphate ions via a “turn-off–on” mechanism

“…Several techniques have been devised for the sensing of ˙OH and PPi such as fluorescence spectroscopy, 9,10 chemiluminescence-derived methods, 11,12 electrochemical biosensors, 13,14 colorimetry 15,16 and various other approaches. Fluorescence-based approaches stand out among them because of their simplified use, noninvasive nature and high sensitivity.…”

“…7 As a result, PPi recognition and quantification is crucial for diagnosing disorders; for example, calcium pyrophosphate dihydrate (CPPD) crystal deposition and chondrocalcinosis disease. 8 Several techniques have been devised for the sensing of OH and PPi such as fluorescence spectroscopy, 9,10 chemiluminescence-derived methods, 11,12 electrochemical biosensors, 13,14 colorimetry 15,16 and various other approaches.

Copper (II) Ion-Modified Gold Nanoclusters as Peroxidase Mimetics for the Colorimetric Detection of Pyrophosphate

“…Until now, a variety of different techniques have been devoted to conducting PPi detection, including fluorescence spectroscopy [ 5 , 6 , 7 ], surface-enhanced Raman-scattering (SERS) assays [ 8 ], colorimetric sensing [ 9 , 10 , 11 ], chemiluminescence [ 12 ], electrochemical analysis [ 13 , 14 ], and dark-field optical microscopy (DFM) [ 3 ]. The principle of most of the above methods is based on the complexation of PPi with metal ions (Al 3+ [ 15 ], Fe 3+ [ 9 , 16 ], Ca 2+ [ 11 ], Zn 2+ [ 17 ], and Cu 2+ [ 5 , 6 , 10 , 12 , 13 , 18 ]), as PPi is a good complexing agent.…”
