Recent Progress in Fluorescent Formaldehyde Detection Using Small Molecule Probes

Recent advances in the detection and removal of heavy metal ions using functionalized layered double hydroxides: a review

“…Fluorimetry shows the advantages of low background, high sensitivity and strong interference rejection, and has attracted wide research interest in the past decades. 47,48 Ligand functionalized nanomaterials (e.g., gold nanoclusters and semiconducting quantum dots) have been applied in the detection of heavy metal ions, including Pb 2+ , Hg 2+ , Cu 2+ , and so on. 49,50 Since the autofluorescence of LDHs is generally ignorable, fluorescent materials are usually introduced to construct LDH-based fluorimetric heavy metal ion detection systems.…”

Diagnosis of Bacterial Plant Diseases via a Nitroreductase-Activated Fluorescent Sensor

“…Growing plant diseases caused by plant pathogens promote the development of plant disease monitoring tools. Compared to those traditional bacterial detection technologies, such as polymerase chain reaction, , enzyme-linked immunosorbent assay, , immunofluorescence, , gas chromatography–mass spectrometry, , surface plasmon resonance, and electrochemical methods, the small-molecule fluorescent probes show some advantages including low cost, easy operation, and noninvasive visualization. − Therefore, more and more small-molecule fluorescent probes for bacterial imaging have been reported . However, most of them aim at human pathogenic bacteria such as Escherichia coli, Staphylococcus aureus, Mycobacterium tuberculosis, and Streptococcus pneumoniae and were applied in human cell and mouse models .…”

Visualization of Polymer–Surfactant Interaction by Dual-Emissive Gold Nanocluster Labeling

“…For example, Yang et al achieved the imaging of the CAC and PSP points of the sodium carboxymethyl cellulose-stepanol WA-100 system [ 18 ]. Among these techniques, the fluorimetry-based ones have attracted wide interest because of their high sensitivity and low background [ 19 , 20 ]. For instance, Jiao et al reported a fluorescence imaging tool that illustrates the CAC and PSP points of chitosan and tetraphenylethene-modified sodium dodecyl sulfonate surfactant (TPE-SDS) [ 21 ].…”
