“…As is well known, a large Stokes shift could efficiently reduce the interference from self-absorption and auto-fluorescence . NIR emission can effectively penetrate tissues or cells and reduce tissue damage, which is beneficial to its application in the biological field. − Accordingly, such a large Stokes shift (95 nm) and long-wavelength emission (710 nm) were promising for applications to biological and food systems.…”

Despite their status of being widely used as food additives, bisulfite (HSO 3 − )/sulfite (SO 3 2− ) can pose serious health risks when they are excessively added. Therefore, it is vital to develop a new method for detecting HSO 3 − /SO 3 2− in foodstuff. In this paper, a benzopyran-benzothiazole derivative (probe DCA−Btl) with near-infrared emission was designed and synthesized by constructing a "push-pull" electronic system. DCA−Btl can selectively recognize HSO 3 − /SO 3 2− via a colorimetric and fluorescence dual channel in DMF/PBS (1:1, v/v, pH = 8.4), and the emission wavelength of DCA−Btl can reach 710 nm. The fluorescence quenching of DCA−Btl after recognition of HSO 3 − is attributed to the photoinduced electron transfer (PET) process of the adduct DCA−Btl-HSO 3 − as evaluated by the DFT/TD-DFT method. In addition, DCA−Btl has many advantages, including a large Stokes shift (95 nm), good anti-interference ability, and little cytotoxicity. What's more, DCA−Btl has been successfully applied for the detection of HSO 3 − /SO 3 2− in actual water samples and food samples such as sugar, red wine, and biscuits with satisfying results, as well as for fluorescent imaging of HSO 3 − in living MCF-7 cells.

“…However, the application of WSN in the industry is not fully understood and current research themes in this area are fragmented [1]. Zhangping Li et al summarize the application of luminescent sensors of iron and copper ions for bioimaging purposes since 2017, including fluorescence, phosphorescence, and bioluminescence [2]. Mansour Mahmoudpour et al outline applications of aerogel-based sensors with a comprehensive overview on the carbon aerogel hybrid materials and their analytical performances.…”

“…Copper can also induce unique cell death in characteristic pathways named cuproptosis [ 7 , 8 ]. Several studies demonstrated that copper is involved in the epithelial to mesenchymal transition and angiogenesis, which are considered to be related to the development and spread of cancer [ 9 , 10 ]. Copper is also atoxic, especially to unicellular microbes, and has been explored as an effective therapeutic agent against infectious pathogens and cancer [ 11 , 12 , 13 , 14 ].…”

Copper is an important trace element that plays a crucial role in various physiological and biochemical processes in the body. The level of copper content is significantly related to many diseases, so it is very important to establish effective and sensitive methods for copper detection in vitro and vivo. Copper-selective probes have attracted considerable interest in environmental testing and life-process research, but fewer investigations have focused on the luminescence mechanism and bioimaging for Cu2+ detection. In the current study, a novel fluorescein-based A5 fluorescence probe is synthesized and characterized, and the bioimaging performance of the probe is also tested. We observed that the A5 displayed extraordinary selectivity and sensitivity properties to Cu2+ in contrast to other cations in solution. The reaction between A5 and Cu2+ could accelerate the ring-opening process, resulting in a new band at 525 nm during a larger pH range. A good linearity between the fluorescence intensity and concentrations of Cu2+, ranging from 0.1 to 1.5 equivalent, was observed, and the limit detection of A5 to Cu2+ was 0.11 μM. In addition, the Job’s plot and mass spectrum showed that A5 complexed Cu2+ in a 1:1 manner. The apparent color change in the A5–Cu2+ complex under ultraviolet light at low molar concentrations revealed that A5 is a suitable probe for the detection of Cu2+. The biological test results show that the A5 probe has good biocompatibility and can be used for the cell imaging of Cu2+.
