A fluorescein-based AND-logic FPSi probe for the simultaneous detection of Hg2+ and F−

A Novel Camphor-Based “Turn-on” Fluorescent Probe with High Specificity and Sensitivity for Sensing Mercury(II) in Aqueous Medium and Its Bioimaging Application

“…7,8 Moreover, once ingested by human bodies, Hg 2+ can result in a wide variety of severe health damages such as neural disorders, abdominal pain, kidney failure, hearing loss, Hunter-Russell syndrome, Minamata disease, pink disease, and even death. 9,10 WHO has explicitly stipulated that the level for Hg 2+ in drinking water should be less than 6 ppb (30 nM). 11 Consequently, developing efficient detection methods for sensitive and specific perception of Hg 2+ in an environment and living cells is an urgent demand.…”

“…The gain of reliable and effective methods for quantitative measurement of various biologically and environmentally prevalent heavy metal ions, such as Pb 2+ , Ni 2+ , Cd 2+ , Cu 2+ , Co 2+ , Zn 2+ , Bi 3+ , and Hg 2+ , is of great significance because of their deleterious effects on environmental security and public health. − Mercury ion (Hg 2+ ) as one of the most virulent and fatal heavy metal ions can easily accumulate in living organisms through food chains. , Moreover, once ingested by human bodies, Hg 2+ can result in a wide variety of severe health damages such as neural disorders, abdominal pain, kidney failure, hearing loss, Hunter-Russell syndrome, Minamata disease, pink disease, and even death. , WHO has explicitly stipulated that the level for Hg 2+ in drinking water should be less than 6 ppb (30 nM) .

Development of a novel AIE active piperazine appended chemosensor for solvent-regulated selective detection of IIB elements [Zn(ii), Cd(ii), Hg(ii)], Cl− and picric acid via varying emission colors to distinguish one another: environmental and biological applications

“…[8][9][10] Parallelly, the accumulation of Hg(II) in the human body causes a wide variety of health damages in terms of neural disorders, abdominal pain, kidney failure, hearing loss, Hunter-Russell syndrome, Minamata disease, etc., and even death. 11,12 Along with cations, several anions are biologically as well as environmentally relevant. If we consider the Cl À ion, then it has a significantly high contribution to cellular functions, including regulation of the transport system in animals.…”

“Switch-Off-On” Detection of Fe3+ and F− Ions Based on Fluorescence Silicon Nanoparticles and Their Application to Food Samples

“…F − ions exhibit the highest charge density, smallest ionic radius, a hard Lewis basic nature, and the most electronegative atom, which enable them to easily combine with metal ions to form the stable compounds [40]. According to this mechanism, many researchers have designed fluorescence sensors to detect the metal ions and F − ions, e.g., Mg [41], Al [42][43][44], Fe-EDTA [45], Ca [46], Hg [47], and Eu [48]. To the best of our knowledge, fluorescence SiNPs have not been used as an environmentally friendly material for the detection of F − ions based on the formation of FeF n -compounds.…”
