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

Abstract

Probe 2a exhibiting high sensitivity, good selectivity, wide pH range, lower detection limit, and rapid detection for Al3+, probe 2a was applied for the successful detection of Al3+ in water samples, food samples and HeLa cells.

A sensitive OFF–ON–OFF fluorescent probe for the cascade sensing of Al3+ and F− ions in aqueous media and living cells

“…Up to now, several uorescent probes for Al 3+ have been designed by various workers. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] And the structures of most uorescent probes for Al 3+ contain nitrogen-oxygen-rich coordination environments which provide a hard-base environment for the hard-acid Al 3+ . These probes, however, have some limitations such as poor water solubility and tedious synthetic procedure, which limited their practical applications.…”

“…Thus, only few examples of Al 3+ probes can be used for cell imaging and biological samples. 5,8,9,[12][13][14][15] Overall, it is still highly desirable to develop novel uorescent probes for Al 3+ which satises several parameters viz. easy and economical synthetic procedure, moderate water solubility and being suitable for cell imaging studies.…”

A hydroxypropiophenone based fluorescent probe for selective determination of Al3+ ions in aqueous ethanol

“…Various Al 3+ sensors based on o-hydroxyphenyl hydrazone have already been reported from our groups as well as other scientists in the world (Peng et al 2021, Kumar et al 2022, Upadhyay et al 2010, Salarvand et al 2019, Shweta et al 2016, Singh and Singh 2014, Singh et al 2013, Dwivedi et al 2018, Alagesan et al 2013, Dwivedi et al 2019, Mao et al 2007, Krishnamoorthy et al2012, Xing et al 2020, Liu et al 2021, Gupta et al 2017, Jiang et al 2019, Kumar et al 2018. The selected receptor H 2 hpoh for the present study can easily be synthesized by a simple and one-step condensation reaction (Scheme 1).…”

A hydroxypropiophenone-based fluorescent probe for the selective determination of Al(III) ions in aqueous ethanol

“…Various Al 3+ ion sensors based on o-hydroxyphenyl hydrazone have already been reported by our group, as well as other scientists around the world [16][17][18][19][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. The selected receptor N' 1 hydrazide (H2hpoh) for the present study can easily be synthesized by a simple and one-step condensation reaction (Scheme 1).…”
