Summary: An innovative electrochemically assisted Fe(III)-NTA/PDS system was proposed for the removal of BPA at neutral pH with efficient decay mainly originating from the continuous activation of PDS by Fe(II) reduced from Fe(III)-NTA complexes. BPA removal occurred mainly through graphite adsorption, direct electron transfer (DET) and radical oxidation, with sulfate and hydroxyl radicals primarily responsible for the oxidation of BPA.

Summary: The Ru(bpy)(3)(2+)-tripropylamine ECL system is widely used in commercial bioanalysis, but the presence of amines in the biological environment causes unwanted anodic interference signals. To overcome this, a cathodic Ru(bpy)(3)(2+) ECL system is proposed, which utilizes the iron-nitrogen-carbon catalyst to activate the ECL signal. This innovative system shows great potential for practical applications, demonstrated by the successful development of an ECL biosensor for detecting alkaline phosphatase activity.

Summary: In recent years, visible light assisted advanced oxidation processes (AOPs) have gained attention in pollutant removal. This study proposes an innovative and eco-friendly system, visible light enhanced Fe3+-tris(2-aminoethyl)amine (Fe3+-NTA)/peroxydisulfate (PDS), for the removal of bisphenol A (BPA). Through ligand-to-metal charge transfer (LMCT), Fe3+-NTA can activate PDS to generate Fe2+ and remove BPA. The results demonstrate that under visible light illumination, efficient BPA removal can be achieved using the appropriate concentrations of Fe3+, NTA, and PDS.

Summary: Palygorskite, as an environmentally friendly adsorbent, can effectively adsorb dyes. This study investigated the carbonized palygorskite for the activation of peroxydisulfate (PDS) to degrade bisphenol A (BPA). The results show that palygorskite carbonized at 800°C exhibits the best performance due to its high carbon defectivity and specific surface area. The carbonized palygorskite can effectively degrade BPA over a wide pH range and is resistant to various anions. The degradation mechanism is attributed to the electron transfer from BPA to PDS via a non-radical pathway.

Summary: Green synthesis of a bio-nanocomposite coating containing egg albumin, chitosan, and carbon dots was achieved, and its physical, chemical, and biological properties were explored for preserving the quality of litchi during storage. The results showed that the coating had good flexibility, antibacterial, antioxidant, and UV barrier properties. Compared to control litchi, the litchi coated with the bio-nanocomposite exhibited reduced browning, weight loss, and reducing sugar content, while maintaining high levels of vitamin C, total sugar, and sucrose, as well as improved color values. This study suggests that the bio-nanocomposite coating can be an eco-friendly method for maintaining litchi quality and reducing postharvest losses.

Summary: In this study, a highly sensitive sandwich-type electrochemical immunosensor for carcinoembryonic antigen (CEA) detection was developed. N-doped hollow mesoporous nanocarbon spheres/gold hybrids (NHMN/Au) were used as the sensing platform and Au/ferrocene (Au/Fc) were used as the signal amplifiers. The NHMN/Au nanomaterials increased the loading of primary antibody and improved the electron transport rate, while Au carried immobilized secondary antibodies and Fc derivative. Using Fc-SH as the response probe, the experiments showed an increased peak current after the specific recognition of Ab(1)-CEA-Ab(2), indicating the successful development of a novel sandwich-type CEA immunosensor. The proposed method was applied to detect CEA in human serum with satisfactory results, demonstrating its significant clinical applications.

Summary: Two fluorescent iridium nanoclusters, IrNCs-1 and IrNCs-2, were prepared by heating IrCl3 in N,N-dimethylacetamide (DMA) and N-Methylformanilide (MFA) respectively, using a facile strategy. The DMA and MFA, being amide compounds with electron-rich oxygen and nitrogen atoms, acted as electron donors and facilitated ligand-to-metal charge transfer (LMCT) complexes formation. The LMCT complexes exhibited excellent fluorescent properties and their emission bands showed red-shifting with increasing excitation wavelength, due to inhomogeneous broadening.

Summary: Antibiotic monitoring is crucial for ensuring human health and safety in the environment and food. Photoelectrochemical (PEC) sensor, as the most popular detection method, offers rapid and accurate antibiotic detection with high sensitivity, easy preparation process, and high selectivity. In this study, a highly efficient visible-light responsive ZnO/C nanocomposite combined with acetylene black was prepared to enhance electron migration efficiency. A molecularly imprinted polymer obtained by electrical agglomeration was conjugated as a specific recognition site for the target. The resulting rMIP-PEC sensor exhibited a low detection limit, wide linear detection range, excellent selectivity, and long-term stability for oxytetracycline (OTC). This work provides a novel approach of using C-doped ZnO semiconductor and molecularly imprinted polymer as photoelectrically active sensing materials for rapid and accurate analysis of antibiotics in food and the environment.
