Abstract
Bluish green emitting fluorescent organic nanoparticles (FONPs) with AIE showed selective sensing of Fe<sup>3+</sup> with a LOD of 12.5 ± 1.2 mM and was exploited in bio-imaging and detection of Fe<sup>2+</sup>/Fe<sup>3+</sup> transition inside cancer cells due to their high H<sub>2</sub>O<sub>2</sub> content.
