“…Human cervical carcinoma HeLa cells and HeLa/DDP which are cis platin-resistant versions of the HeLa cells were used. A table of the linear range and comparison to other fluorescent Cu 2+ probes were made; linear ranges were prepared and the detection limit for the probe in question was determined to be 0.4 nM [154].…”

In this review from literature appearing over about the past 5 years, we focus on selected selenide reports and related chemistry; we aimed for a digestible, relevant, review intended to be usefully interconnected within the realm of fluorescence and selenium chemistry. Tellurium is mentioned where relevant. Topics include selenium in physics and surfaces, nanoscience, sensing and fluorescence, quantum dots and nanoparticles, Au and oxide nanoparticles quantum dot based, coatings and catalyst poisons, thin film, and aspects of solar energy conversion. Chemosensing is covered, whether small molecule or nanoparticle based, relating to metal ion analytes, H2S, as well as analyte sulfane (biothiols—including glutathione). We cover recent reports of probing and fluorescence when they deal with redox biology aspects. Selenium in therapeutics, medicinal chemistry and skeleton cores is covered. Selenium serves as a constituent for some small molecule sensors and probes. Typically, the selenium is part of the reactive, or active site of the probe; in other cases, it is featured as the analyte, either as a reduced or oxidized form of selenium. Free radicals and ROS are also mentioned; aggregation strategies are treated in some places. Also, the relationship between reduced selenium and oxidized selenium is developed.

“…The sensing of heavy and transition metal ions via recognition of molecules is one of among the most useful and interesting research fields, due to its special role in environmental, medicine, and biological sciences. [1][2][3] Copper is among the most abundant essential trace elements in the world's crust besides iron and zinc and is a vital transition metal element in both environmental and biological systems. Copper(II) ions play an essential role in many physiological processes such as neurotransmitter, blood cell formation, iron metabolism, free radical detoxification, and antioxidant defense in organisms ranging from bacteria to mammals.…”

A highly efficient, selective, sensitive, and colorimetric chemosensor SB for Cu 2+ detection with turn-on fluorescence behavior in CH 3 -water solution was synthesized. A good enhancement of the intensity of fluorescence was detected by the incremental addition of Cu 2+ after excitation at 286 nm. The fluorescence quantum yield (Ф) of SB-Cu 2+ was calculated for 0.41. The responsive mechanism of SB to copper ion is involved for on the combined effects of C═N isomerization and intramolecular charge transfer (ICT) process and chelationenhanced fluorescence (CHEF). The detection limit for the fluorescent chemosensor SB toward Cu 2+ was 0.6 Â 10 À6 M.

“…Compounds containing binding sites, uorophores, and a communication mechanism between the two sites are called uorescent probes or uorescent chemosensors (Wu et al 2017). Fluorescent probes typically achieve uorescence imaging through one or more common photophysical mechanisms, including intramolecular charge transfer (ICT) (G. Yang et al 2013), excited-state intramolecular protontransfer (ESIPT) (Lu and He 2021), photo-induced electron transfer (PET) (Li et al 2019), chelationinduced enhanced uorescence (CHEF) (Slassi et al 2019), aggregation-induced emission (AIE) (Lin et al 2019), etc. and the number of methods is increasing.…”

Background Fluorescent probes are used to detect and label the corresponding substances and play an important role in the detection of brain diseases. However, the general research trends in this field are poorly understood. This article explores trends in the application of fluorescent probes in brain diseases from a bibliometric perspective. Aim This holistic bibliometric analysis aim to provide a general overview of the recent advancement and the hotspots in the field of fluorescent probe from 2002 to 2022. Materials and Methods Publication between January 1 2002 and December 31 2022, relate to fluorescent probes and brain diseases research are acquired from the Web of Science Core Collection (WOSCC) database. Analysis of the volume of keyword occurrences use VOSviewer software, Scimago Graphica software is applied to country analysis, and keyword clustering, author collaboration, and institutional collaboration use CiteSpace software. Results A total of 1927 publications are extracted from the WOSCC databases. Publications are mainly from China. The keywords are divided into seven clusters, including multiple sclerosis, tumor, oxidative stress, alzheimers disease, reactive oxygen species, plasma, infection; of which, gene, single nucleotide polymorphism, schizophrenia, haplotype, apolipoprotein e, bipolar disorder are the original research hotspot in the field. Peptide, biosensor, aggregation induced emission are the main areas researched in recent years. Conclusion Current research on fluorescent probes and brain disorders have attracted increasing attention in the past two decades. This study provides a comprehensive view to understand the research trends, hot topics of research and research progress in this field.
