A highly sensitive and selective fluorescence chemosensor for Fe3+ based on rhodamine and its application in vivo imaging

Recent Advances on Iron(III) Selective Fluorescent Probes with Possible Applications in Bioimaging

“…The probe 29 shows a good linearity range from 0.8 to 20 μM with the estimated LOD of 11.6 nM [37]. The probe 30, possessing rhodamine and anthracene, detects Fe 3+ down to 42 nM and has been applied successfully to monitor Fe 3+ ions in living cells and zebrafish (Figure 2) [38]. The furfuran-based rhodamine B fluorescent probe 31 can be applied to detect Fe 3+ down to 0.025 μM, and the turn-on fluorescence due to the 31-Fe 3+ complex formation is shown to be reversed upon addition of B 4 O 7 2 − [39].…”

Bifunctional Cu2+/Fe3+ Probe with Independent Signal Outputs Based on a Photochromic Diarylethene with a Dansylhydrazine Unit

“…50,51 Subsequently, the LOD of 1O toward Fe 3+ was determined to be 9.73 × 10 –8 mol L –1 by the concentration-dependent fluorescence titration experiment (Figure 6C). Compared to other Fe 3+ sensors, 52−54 the LOD of 1O was much lower, suggesting that diarylethene 1O could serve as a good fluorescence sensor for Fe 3+ with high sensitivity and sensitivity.…”

A novel boronic acid-based fluorescent sensor for selectively recognizing Fe3+ ion in real time

“…11,17 However, to the best of our knowledge, there is no boronic acid-based sensor reported for Fe 3+ ion and we reported the rst one. Over past years, there are a good number of uorescent sensors for Fe 3+ have been reported, which are usually based on derivatives of macrocyclic molecules, 2,28 rhodamines, [29][30][31][32][33][34] coumarin, 36,37,56,57 quinoline, 1,[38][39][40] etc. These mother core structures usually were further modied with other functional groups, such as Schiff base.…”

“…), carbohydrates [24][25][26][27] and so on. Compared with sensing other transition metals such as Cu 2+ and Hg 2+ , there are relatively less uorescent sensors of Fe 3+ ion, which are based on derivatives of macrocyclic molecules, 2,28 rhodamines, [29][30][31][32][33][34] coumarin, [35][36][37] quinoline, 1,[38][39][40] etc. However, most Fe 3+ ion sensors reported have irreversible recognition, 30,41 long response time, 1,29,36,42 poor water solubility, 28,42,43 and are susceptible to interference from other transition metal ions such as Zn 2+ , Cr 3+ and Pb 2+ .…”
