A near-infrared fluorescent probe for rapid detection of carbon monoxide in living cells

A highly selective aggregation‐induced emission fluorogen for sensitive detection of Al3+ in living cells

“…There was a good linear relationship between fluorescence intensity (455 nm) and Al 3+ concentration in the range of 0.48–25 μM, conforming to the linear equation y = 7.5 + 10.4 × (R 2 = 0.9912) (Figure b). The detection limit of probe 1 could be calculated as 1.4 × 10 −8 M according to the reported method when the signal‐to‐noise ratio was 3 and the relative standard deviation was 4.8% . Therefore it could be affirmed that probe 1 has a high detection sensitivity.…”

Small-molecule fluorescent probes for imaging gaseous signaling molecules: current progress and future implications

“…By regulating the ICT process, some uorescent probes have been constructed by researchers to detect CO (probes 43-45). [61][62][63] These probes exhibit signicant colorimetric changes, high selectivity and sensitivity toward CO, which can be effectively used to visualize CO in vitro, in living cells or in vivo.…”

Recent Advances in Fluorescence Light‐Up Endogenous and Exogenous Carbon Monoxide Detection in Biology

“…It has also been applied to get cell image in MCF-7 cells due to its bright fluorescence. [57] Gao et al reported a simple NIR range probe COÀ B having allyl ether as the reaction site and generates red fluorescence to detect CO based on Tsuji-Trost reaction in presence of CORM-3 ( Figure 17A). COÀ B contained large Stokes shift, good water solubility, pH independency, decent cell membrane permeability, light-up NIR emission, and sensitive response with low toxicity.…”
