Summary: In this study, a new ratiometric fluorescent sensor was developed by encapsulating blue-fluorescent carbon dots (B-CDs) with SiO2, coupling gold nanoclusters (GSH-AuNCs) to the surface, and anchoring a layer of Ag+. The presence of UO22+ resulted in fluorescence quenching of the ratiometric fluorescent probe in aqueous solutions, attributed to photoinduced electron transfer (PET) between B-CDs@SiO2@GSH-AuNCs/Ag+ and UO22+. With excellent selectivity, the ratiometric fluorescent probes detected UO22+ at 37 nmol/L and showed promising potential for convenient monitoring of UO22+ levels in real-world water samples.

Summary: This study investigates the Photoinduced Electron Transfer (PET) reaction between a donor (adenine analogue) and an acceptor (3-methoxychromone dye, 3MC) for designing efficient fluorescent probes as DNA sensors. The research reveals that in conjugated systems, the electron transfer between the donor and acceptor is the main cause of fluorescent quenching.

Summary: A newly amino-functionalized luminescent Zr-based metal-organic framework (NU-1000-NH2) was designed for ultra-sensitive fluorescent detection of nitroaromatic explosives. The amino constructed in cavities of NU-1000NH2 can capture and bind the nitroaromatic molecules, causing fluorescence quenching due to the electron donor-acceptor interaction. The hydrogen-bonding effect between NU-1000-NH2 and analytes was also found assisting for binding and recognizing nitroaromatic explosives molecule.

Summary: Due to the significant hazardous impact of Hg2+ on the environment and ecosystem, there is a need for highly sensitive and selective Hg2+ probes. A new imidazole-based Hg2+ probe has been synthesized and characterized, which can detect Hg2+ through an ion-specific co-ordination mechanism. The probe exhibits significant fluorescence enhancement in acetonitrile solutions containing Hg2+, with a limit of detection of 0.30 mu M. Additionally, it shows utility in detecting Hg2+ in biochemical systems and the environment based on paper test strip and HeLa cell experiments.

Summary: Typical PeT-based fluorescent probes are multi-component systems that utilize a fluorophore connected to a recognition/activating group through an unconjugated linker. These probes have been widely used in cell imaging and disease diagnosis due to their low background fluorescence and significant fluorescence enhancement towards the target. This review summarizes the research progress made in the past five years on PeT-based fluorescent probes targeting cell polarity, pH, and various biological species, emphasizing molecular design strategies, mechanisms, and applications. By providing guidance and promoting the development of new and improved PeT-based fluorescent probes, this review aims to promote the use of PeT-based systems for sensing, imaging, and disease therapy.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.

Summary: Nanozyme based sensors have been developed as an effective method for detecting harmful metal ions in water samples. In this study, a Co(II) based coordination polymer nanoparticle (Co-CP NP) was synthesized and utilized as a nanozyme to detect Fe(II) ions selectively. The Co-CP NP exhibited peroxido-reductase mimicking activity, and the detection limit for Fe(II) ions was found to be 0.66 μM. The catalytic action of the Co-CP NP was further analyzed using Michaelis-Menten kinetics, and the detection mechanism was elucidated through XPS and zeta potential analysis.
