Fluorescence detection of fluorine ions in biological fluids based on aggregation-induced emission

Abstract

Schematic diagram of fluorescence detection of F− ions in biological fluids based on TPE-COOH/Al3+ polymer Aggregation-Induced Emission (AIE) “Turning on–off” mode.

Bioinspired 3D Hierarchical UiO-66-NH2 Nanoparticle/γ-AlO(OH) Nanowire for Simultaneous Detection and Removal of Fluoride Ions

“…The limit of detection (LOD) was determined by the following formula where σ is the standard deviation obtained from the parallel blank experiment. The LOD of F – detected by UiO-66-NH 2 /γ-AlO­(OH) was calculated to be 0.77 μM, which was lower than those of most reported materials, such as SPBH, B, N-GQDs, and [EuL 2 (NO 3 ) 3 ]·H 2 O …”

“…The LOD of F − detected by UiO-66-NH 2 /γ-AlO(OH) was calculated to be 0.77 μM, which was lower than those of most reported materials, such as SPBH, 45 B, N-GQDs, 46 and [EuL 2 (NO 3 ) 3 ]•H 2 O. 47 Figure 3f shows the reusability of the sample in fluorescence detection. As can be seen from the figure, the fluorescence intensity used to detect F − had almost no change after four times of repeated use, indicating that UiO-66-NH 2 /γ-AlO(OH) has good reusability in fluorescence detection.…”

ROS-responsive polymeric micelles with aggregation-induced emission effects for drug delivery and cellular imaging

“…Incorporating AIE-active species into nanocarriers constructed from amphiphilic polymers offers an effective approach for achieving fluorescence imaging (FLI), 18 enhancing biocompatibility, stability, and potential for tumor diagnosis and treatment. 12,25 By introducing AIE molecules, such as TPE, into amphiphilic block copolymers and simultaneously loading anticancer drugs, [26][27][28] multifunctional nanocarriers can be developed to observe the distribution of polymer nanoparticles in vitro and in vivo. 29 In drug-loaded nanocarriers, the formation of fluorescence resonance energy transfer (FRET) between drugs and the nanocarrier can further elucidate the drug release process in drug delivery systems.…”

Constructing spin crossover-fluorescence bifunctional iron(ii) complexes based on tetraphenyl ethylene-decorated AIEgens

“…Tetraphenyl ethylene (tpe) and its derivatives have been used in many fields, including chemical sensors, smart materials, bioimaging, and active layers in the fabrication of OLEDs because of their simple molecular structures, easily functionalized character, and efficient AIE behavior. [53][54][55][56] Owing to their propeller-like structure, tpe and its derivatives are expected to preserve strong fluorescence when introduced into the SCO system.…”
