“…Iron disturb metabolism may affect the concentration of reactive oxygen species which can maintain stability under normal condition. As an ROS, hydroxyl radical produced during the Fenton reaction can seriously damage the cells [7]. The signi cant change of iron concentration could seriously affect the normal cellular event.…”

The transition between its various oxidation states of Iron plays a crucial part in various chemical transformation of cells. Misregulation of iron can give rise to the iron-catalyzed reactive oxygen species disorder which have been linked to a variety of diseases, so it is crucial to monitor the labile iron pool in vivo for clinical diagnosis. According to iron autoxidation and hydrogen abstraction reaction, we reported a novel "off-on" uorescent probe to response to ferrous (Fe 2+ ) both in solutions and biological systems.The probe responds to Fe 2+ with good selectivity toward competing metal ions. What's more, the probe presents signi cant uorescent enhancement to Fe 2+ in less than 1 min, making real-time sensing in biological system possible. The applications of the probe in bioimaging revealed the changes in labile iron pool by iron autoxidation or diverse stimuli.

“…Iron and copper ions, which are biological metals, play significant roles in these processes [2][3][4]. Iron exists in the form of ferrous (Fe 2+ ) and ferric (Fe 3+ ) ions and is indispensable in physiological processes such as oxygen binding, respiration, and enzymatic reactions [5][6][7][8]. Although it is of great importance in physiological processes, iron deficiency causes diabetes, anemia, liver, heart, and kidney damage, and iron accumulation causes serious diseases such as cancer, Parkinson's, and Alzheimer's [9][10][11].…”

Iron and copper ions detection are very important for environmental and biological processes. In this work, novel pyrene-functionalized Schiff base chitosan (Chit-Pyr) was synthesized, and this hybrid material was used as a “turn-off” fluorescence sensor for the detection of Fe2+, Fe3+, and Cu2+ ions. FTIR, UV-Vis, TGA, and SEM were used to examine for structural, thermal, and morphological properties of Chit-Pyr. This sensor exhibited a selectivity towards Fe2+, Fe3+, and Cu2+ ions among several common metal cations in the DMF dispersion. The results obtained that the proposed “turn off” fluorescence sensing mechanism of Chit-Pyr was simple and sensitive for the determination of Fe2+, Fe3+, and Cu2+ ions.

“…30,31 Therefore, we can choose pomegranate peel as a spectroscopic sensor to detect iron. In the present work, in continuing our recent researches in the determination of biological and metal cations and anions, [32][33][34][35][36][37] we proposed a biocompatible, green, natural, selective, and sensitive spectroscopic detection and measurement of Fe 3+ and Fe 2+ . The method was successfully employed to specify and quantify the cited ions in real matrix water samples without complicated pretreatment using multivariate calibration methods.…”

A simple, novel, biocompatible, and sensitive spectrophotometric method was developed for colorimetric detection and speciation of Fe3+ and Fe2+ ions. The method is based on the complex formation of Fe3+ and Fe2+ with organic constituents containing functional groups in pomegranate peel extract (PG). Developing of the color is specifically established in the presence of Fe3+ and Fe2+. Accordingly, in addition to direct detection of both cations, we carried out a quantitative multivariate model for their accurate determination in real matrix aqueous samples. Due to spectral interference, the simultaneous determination of Fe3+ and Fe2+ mixtures using spectrophotometry is a problematic issue. A combined multivariate as partial least squares (PLS)–artificial neural network (ANN) was used to create and adjust a model and predict said cations in test and real sample sets. In this context, the calibration model is based on absorption spectra in the 400–900 nm range for 98 different mixtures of Fe3+ and Fe2+. Calibration matrices contained 1–12 and 1–10 μg ml−1 of Fe3+ and Fe2+, respectively. The detection limits for Fe3+ and Fe2+ were 0.53 and 0.14 μg ml−1, respectively. The root mean square error of prediction (RMSEP) for Fe3+ and Fe2+ with PLS‐ANN was 0.78, 1.65 and 1.062, 0.894 in Kalugan waterfall and Tehran tap water. This strategy can simultaneously determine Fe3+ and Fe2+ in real matrix samples, and the reliability of the determination is acceptable.
