AIE-based Tb3+ complex self-assembled nanoprobe for ratiometric fluorescence detection of anthrax spore biomarker in water solution and actual spore samples

Tetraphenylethylene-based Eu3+-metallopolymers with aggregation-enhanced white emission for self-calibrating temperature sensing and white light-emitting diodes (WLEDs)

“…Ln 3+ -containing metallopolymers have aroused much research interest in recent years. 1–3 Owing to the advantages of high colour purity and high photoluminescence efficiency of the inorganic Ln 3+ ion, 4–6 as well as the superior mechanical properties of the organic polymer backbone, they have been good candidates for application in solid state lighting devices, 7 barcodes, 8 sensors 9 or biological imaging. 10 Particularly, the feasibility of combining multicolour emissive Ln 3+ ions into a single phase metallopolymer endows them with advantages for fabricating white light emitting materials, however, compared to the extensively studied white light emitting Ln 3+ -based complexes, 11 coordination polymers 12 or quantum dots, 13 high-efficiency white light emitting Ln 3+ -metallopolymers are still rarely reported.…”

Recent Progress in Identifying Bacteria with Fluorescent Probes

“…In recent years, Ir(III), Ru(II), Os(II), Re(I), Pt(II), Au(I), Cu(I), and Zn(II) complexes have been used in the field of bacterial detection and imaging [ 112 ]. The luminescence properties of rare earth complexes are similar to those of AIEgens, as rare earth complexes generally have high luminescence efficiency both in aggregate and solid form [ 113 ]. Gupta et al developed a new ring metal iridium (III) complex ( 1 – 3 ) ( Figure 20 ), a cationic Ir(III) complex combined with negatively charged phosphoric groups on LPS and LTA through electrostatic interaction to form LPS/LTA-Ir(III) aggregates, resulting in strong intermolecular p–p stacking to achieve rapid detection and suppression of drug-resistant bacteria [ 114 ].…”

A multi-ratiometric fluorescence sensor integrated intrinsic signal amplification strategy for a sensitive and visual assay of the anthrax biomarker based on a bimetallic lanthanide metal–organic framework

“…To date, numerous approaches have been reported for the determination of DPA, such as colorimetry, 9,10 electrochemistry, 11 surface-enhanced Raman scattering spectroscopy, 12,13 and fluorimetry. [4][5][6][7][8][14][15][16][17][18][19][20][21][22][23][24][25][26][27] Among these, fluorimetry has been widely adopted owing to its high sensitivity, quick response, and ease of operation. 28 In particular, ratiometric fluorimetry has attracted considerable research interest for DPA determination because it can achieve a more sensitive detection and visual analysis by simultaneously recording the change of different fluorescence signals.…”
