A water-soluble and reversible fluorescent probe for Al 3+ and F − in living cells

A highly sensitive and selective fluorescent probe for quantitative detection of Al3+ in food, water, and living cells

“…[16][17][18][19][20][21][22][23][24][25] However, there are still some shortcomings in reported Al 3+ uorescent probes, including a complex synthesis process, poor selectivity and sensitivity, easy interference by other metal ions, Zn 2+ , Cu 2+ , Cr 3+ , Hg 2+ , and even F À , [26][27][28][29][30] and lack of applicability to water samples and food samples. [31][32][33][34][35] Therefore, developing a uorescence probe with high sensitivity, good selectivity, rapid response and low toxicity for detecting Al 3+ is particularly meaningful.…”

Fabrication of an acylhydrazone based fluorescence probe for Al3+

“…In the last decade, many traditional analytical techniques like as ion chromatography (IC), atomic absorption spectrometry (AAS), inductively coupled plasma mass spectrometry (ICP-MS) are the most commonly employed analytical techniques used for the determination of Al 3+ and others [8]. Though these techniques generally provide accurate results, but are not very convenient for the determination of a large number of samples as they require enormous infrastructure backup, expertise and time consuming procedures.…”

“…However, many of them have suffered from cost of synthesis, the number of synthesis 6 steps, selectivity [60][61][62][63], binding constant, detection limit (except few cases [64,65]), use of harmful organic solvents, and poor water solubility ( except few cases [8,42,64] ).…”

A europium(III) metal-organic framework as ratiometric turn-on luminescent sensor for Al3+ ions

“…From this point of view, LnMOFs with ligand and Ln 3+ emissions are very attractive, because organic ligands and Ln 3+ ions as the luminescent centers possess completely different physical and chemical properties and they would produce different interactions with analytes. Thus, LnMOFs have been extensively applied to construct ratiometric sensors recently [3,22].Aluminium exists in soil, containers and structural materials, which may release Al 3+ due to the corrosion and/or dissolvation, inducing the increasing risk of Al 3+ absorption by the human body [23][24][25][26][27]. However, excessive Al 3+ in human body may cause damage to nucleic acids and proteins or the central nervous system [28][29][30].…”
