Summary: In this study, a highly sensitive method for the determination of glutathione S-transferase (GST) was developed using a fluorescent nanosensor. The nanosensor, based on the assembly of HgZnSe quantum dots (QDs) and zeolitic imidazolate framework-8 (ZIF-8), exhibited enhanced fluorescence and improved analytical sensitivity. The platform relied on the selective enrichment of Cu2+ on the surface of ZIF-8@QDs, resulting in fluorescence quenching. However, the presence of glutathione (GSH) led to the recovery of fluorescence due to the strong affinity between Cu2+ and GSH. The catalysis of GST caused GSH to react with 1-chloro-2,4-dinitrobenzene (CDNB), resulting in the formation of an adduct that quenched the fluorescence of ZIF-8@QDs. This simple and sensitive fluorescence sensing platform showed a wide linear range of 0.05-1.2 mU/L for the determination of GST, with a limit of detection (LOD) of 0.014 mU/L. The study highlights the potential of designing and synthesizing high-performance MOF-based nanoprobes for in vitro diagnosis, with applications in bioinformatics and clinical medicine.

Summary: We synthesized water-soluble CdTe quantum dots (CdTe QDs) with longer emission wavelength and constructed a luminol-CdTe QDs chemiluminescence resonance energy transfer (CRET) system for high selectivity ratio detection of Cu2+. The system discovered that the paramagnetic ion Cu2+ generally binds more strongly to the sulfhydryl group (S-H) on CdTe QDs, which leads to surface defects and quenches the chemiluminescence (CL) signal. The method achieved a highly sensitive, selective, and reliable measurement of Cu2+ with a low detection limit of 8.4 nM, and has successfully detected Cu2+ in tap water and lake water.

Summary: Current quantum systems based on spin qubits suffer from a bottleneck caused by the use of classical electronics located outside the cryostat. To address this issue, a scalable memristor-based programmable dc source is proposed to control the biasing of quantum dots (QDs) inside the cryostat. Experimental resistance programming and simulations demonstrate the feasibility of this cryogenic approach, showing a wide voltage range and high resolution in situ memristor-based dc source for controlling double quantum dots (DQDs).

Summary: Recent research has shown that low-dimensional materials, such as quantum dots and core-shell quantum dots, exhibit strong nonlinear optical behavior and have potential applications in photo-electronics, photovoltaic nonlinear optics, light-emitting diode fabrication, and laser protections. Variations in core-shell shape and size, as well as the chemical composition of quantum dots, define their enhanced nonlinear optical properties. Specific nonlinear optical properties, such as nonlinear refraction, optical limiting, saturable absorption, and reverse saturable absorption of CdTe and CdSe quantum dots, along with core-shell quantum dots and their applications, were assessed in this study.

Summary: The emission of volatile sulfur compounds (VSCs) poses risks to the environment, product quality, and human health. Establishing sensitive and convenient analytical methods for VSCs detection is of great importance. Chemiluminescence (CL) and cataluminescence (CTL) offer promising techniques for VSCs detection due to their fast response, high sensitivity, and simplicity. CL analysis has been widely applied in various fields using auxiliary CL methods and sulfur chemiluminescence detector (SCD), while CTL detection is prosperous in the construction of gas sensors, including the exploration of sensing materials and detection modes.

Summary: In this study, a unique two-photon fluorescent probe (ER-ONOO-) was developed to detect ONOO- in aqueous solution with high sensitivity, high selectivity, and ultrafast response time. The probe successfully evaluated the levels of ONOO- at the endoplasmic reticulum (ER) in a hypoxia-induced endothelial injury model. Furthermore, it was able to monitor the changes in organ fluorescence through ONOO- variation in different stages of a cecum ligation and puncture (CLP) mouse model. The study confirmed the involvement of endoplasmic reticulum stress and oxidative stress in the CLP model, providing a reliable tool for studying ONOO- fluctuation in sepsis and offering new insights into the pathogenic and therapeutic mechanisms involved.

Summary: In recent years, the use of advanced oxidation processes (AOPs) based on peracetic acid (PAA) has gained attention for its high oxidative potential and low byproduct formation. However, there is still a need to study the activation of PAA and the degradation mechanism to develop more efficient and stable PAA-based AOPs. This study investigates a new PAA-based AOP activated by metal-organic framework-derived cobalt phosphide (CoP) and accompanied by chemiluminescence (CL) behavior. The CoP/PAA system showed efficient degradation of RhB, with a degradation rate 23.7 times higher than that of the conventional Co3O4/PAA system, and the degradation process was confirmed to be driven by O-1(2).

Summary: In this study, nitrogen-doped carbon dots (N-CDs) were found to significantly enhance the chemiluminescence (CL) intensity of the Ce (IV)-Na2S system. The mechanism was explored and discussed through experiments with free radical scavengers, CL spectra, and X-ray photoelectron spectroscopy (XPS). The enhancement is mainly attributed to the chemiluminescence resonance energy transfer (CRET) between (1O2)2*/Ce (III)* and N-CDs, where mono-dispersed N-CDs catalyze the production of more 1O2 on their surface. The new CL system was successfully utilized for the detection of H2S with a linear range of 20-200 nM and a limit of detection (LOD) of 0.32 nM. The system also demonstrated good recovery rates in different water samples, making it a promising platform for practical applications.
