Fluorescent organic nanoparticles (FONs) of rhodamine-appended dipodal derivative: highly sensitive fluorescent sensor for the detection of Hg2+ in aqueous media
A new fluorescent sensor 5 having fused imidazopyridine scaffold has been synthesized via cascade cyclization. It exhibits highly sensitive and selective detection of Fe3+ (‘turn-on’) and Hg2+ (‘turn-off’) in vitro and in HeLa cells.
An organic–inorganic nanohybrid complex of a tripodal complex was used for the selective determination of spermidine and its use in real sample analysis.
Fluorescent organic nanoparticle (FON)-based chemosensors are emerging as a valuable tool for the fast and accurate detection of metal ions in aqueous media. In this review, we highlight the recent developments in this field.
