A novel fluorescent probe of aluminium ions based on rhodamine derivatives and its application in biological imaging

Abstract

With the rapid development of fluorescence detection technology, people have put forward higher requirements for probes. Based on this, we designed and synthesized the probe RBJF, which has high selectivity...

Fluorescent dyes based on rhodamine derivatives for bioimaging and therapeutics: recent progress, challenges, and prospects

“…21). 68 In MeOH/H 2 O (1 : 1, v/v) solution, the five-membered ring structure of RBJF was in a closed state. However, the addition of Al 3+ to the solution induced the opening of the rhodamine ring owing to the rapid binding of Al 3+ to the N and O atoms in the probe, resulting in a strong fluorescence effect and color change that is visible to the naked eye.…”

“…Therefore, several researchers have utilized this property to develop various rhodamine-based probes for the detection of intracellular microenvironmental changes, metal ion levels, and various biomarkers. [67][68][69][70] To expand the application of rhodamine fluorophores, several researchers have prepared rhodamine derivatives with different absorption and emission wavelengths using various strategies. For example, Nagano et al developed a series of new nearinfrared (NIR) wavelength-excited rhodamine dyes by replacing the central oxygen atom with the silicon atom.…”

Synthesis and performance study of a ratiometric fluorescent probe for Hg(Ⅱ) detection

“…The conjugated system and rigid coplanar in its structure make its fluorescence tend to a stable state, which makes it have the characteristics of strong light stability, wide wavelength range, high fluorescence quantum yield and low pH sensitivity. It can be widely used in discipline research, biological detection, environmental protection and other fields [14][15][16][17].…”

Fabrication of Orange Fluorescent Boron-Doped Graphene Quantum Dots for Al3+ Ion Detection

“…Therefore, it is very important to detect aluminum in order to reduce its intake into the human body. The methods for detecting metal ions include electrochemical methods, precipitation methods, spectral methods, chromatography, and so on [ 2 , 3 ]. These methods can effectively detect metal ions, but their operation is complex and costly, involves expensive equipment, and they cannot quickly and sensitively identify metal ions.…”
