Schiff Base Fluorescent Moiety Salicylideneaniline as a Dualchannel Chemosensor: A Hg<SUP>2+</SUP>/Cu<SUP>2+</SUP> Switchable Logic Gate

Fluorescent organic nanoparticles (FONs) for selective recognition of Al3+: application to bio-imaging for bacterial sample

“…[1][2][3][4] Although analytical techniques as atomic absorption spectroscopy, colorimetric assays, spectrophotometry and voltammetry can effectively detect and quantify metal ions, these methods are either time consuming procedures or use sophisticated instrumentation; however, spectro-uorescence has high sensitivity, selectivity, rapidity and an easy operational procedure. [5][6][7] Sensors based on changes in uorescence induced by chemical species are highly sensitive, rapid, simple and there is real-time monitoring of the uorescence, and they are able to detect numerous metal ions in biological samples [8][9][10][11][12][13] as follows: Ca(II), 14 Mg(II), [15][16][17] Pb(II), [18][19][20] Cd(II), [21][22][23] Al(III), [24][25][26][27] Cr(III), 28,29 Hg(II), [30][31][32][33][34] Fe(II), 35 Co(II), 36,37 Ni(II), 38,39 Zn(II), [40][41][42][43][44][45]…”
