A novel rhodamine-based fluorescent probe for the fluorogenic and chromogenic detection of Pd2+ ions and its application in live-cell imaging

A Piperazine Linked Rhodamine‐BODIPY FRET‐based Fluorescent Sensor for Highly Selective Pd2+ and Biothiol Detection

“…0.5, suggesting a 1 : 1 binding ratio of PRS and Pd 2+ (Figure S36). For the NMR titration of PRS with Pd 2+ (Figure S18), as shown by the chemical shift values [19a–d] of the podand ligand, addition of 1 equivalent of Pd 2+ caused a complete transformation of the original species into the complexed form, with no further changes observed after the addition of 2 equivalents of Pd 2+ . Unfortunately, the PRS‐Pd complex could not be identified by high resolution ESI‐MS, possibly due to decomposition of the BODIPY unit during the high energy ionization process [19e] .…”

A ready‐to‐use fluorescence probe of Pd2+ in water: novel tricyclic heterocyclic base on 1,3,4‐oxadiazole

“…It is a serious hazard to animals and plants. [4] Therefore, there is an urgent need to explore a quick, selective, and sensitive method to detect Pd 2+ .…”

Dual Fluorescence and NMR Study for the Interaction between Xanthene Dyes and Nanoparticles

“…2,17 In this work, we use an inexpensive rhodamine dye, rhodamine B (RhB), as a model for xanthene dyes because its derivatives have been extensively applied in many areas. 9,10,18 Because of their unique physicochemical properties, nanoparticles (NPs) are important in the biomedical field. To date, NPs have been used in drug delivery, bioimaging, and as biosensors.…”

“…Nonfluorescent and colorless rhodamine spirolactam or spirolactone derivatives will change color to pink and emit fluorescence once the spirolactam/lactone ring is opened. ,, Researchers have taken advantage of this characteristic and applied rhodamine and its related derivatives to many fields, including applications in biological markers and bioimaging. − For instance, rhodamine derivatives have been extensively used as fluorescent chemosensors to sense biologically and environmentally related metal ions (Cu 2+ , Hg 2+ , Zn 2+ , Pd 2+ , etc. ) − to detect pH , and to monitor enzyme activity. − Compared with other sensing methods, fluorescent probes can be easily introduced into the system and are highly sensitive and selective . For these reasons, fluorescence imaging is excellent in providing real-time imaging in cells. , In this work, we use an inexpensive rhodamine dye, rhodamine B (RhB), as a model for xanthene dyes because its derivatives have been extensively applied in many areas. ,, …”
