A new “off–on” fluorescent probe for Pd2+ in aqueous solution and live-cell based on spirolactam ring-opening reaction

A new “off–on” fluorescent probe for Al3+ in aqueous solution based on rhodamine B and its application to bioimaging

“…The binding stoichiometry of the RBP-Al 3+ complex was studied based on literature method [26]. Job's plot experiment was estab- respectively.…”

A smart NIR fluorescent probe for the highly selective detection of palladium

“…[6][7][8] In recent years, optical probes, including colorimetric or uorescent probes, emerged as powerful alternatives to monitor and sense palladium species because of their convenience, on-site detection, ease of manipulation and biological applications. [9][10][11][12][13] In particular, uorescent probes with near-infrared (NIR) emission are extremely favourable for bioimaging because of deep penetration and minimum auto-uorescence. 14,15 However, most of the reported probes for palladium display absorbance and emissions in the visible region, which greatly restricts their applications in biological imaging.…”

An effective ICT-based and ratiometric fluorescent probe for sensing sulfite

“…Ratiometric fluorescent probes can eliminate most of interferences by measuring the ratio of fluorescence intensities at two different emission wavelengths [27]. They are more appropriate for biomolecule imaging and qualitative or quantitative analysis in comparison with quenching and intensive fluorescence probes [28]. Thus, we need to develop novel ratiometric fluorescent probe for the detection of sulfite.…”
