Bimetallic-Doped Metal-Organic Gel for Efficient Electrochemiluminescence: Staircase-Mediated Energy Transfer and Applications in Epinephrine Detection.

This study presents the development of a novel bimetallic-doped metal-organic gel (Tb-Eu-MOG) synthesized by codoping terbium (Tb(III)) and europium (Eu(III)) with the Hcptpy ligand and explores its application in electrochemiluminescence (ECL) for sensitive detection of epinephrine (EP). The Tb-Eu-MOG exhibits unique petal nanoflower-like morphology and remarkable ECL signals, attributed to the dual sensitization effects of Tb(III) and Eu(III) on the Hcptpy ligand. The Tb(III) doping facilitates energy transfer and enhances ECL efficiency through a staircase effect.

Amines-enriched vertically-ordered silica nanochannels for conductivity-regulated electrochemiluminescence sensing and bacterial metabolism detection.

An innovative amine-enriched vertically-ordered mesoporous silica film (VMSF) on indium tin oxide (ITO) electrodes (A-VMSF/ITO) utilizing an anionic template strategy was successfully developed, resulting in the inner walls of the nanochannel being adorned with well-ordered and abundant tertiary amine groups. In the context of A-VMSF/ITO, the elevated solution conductivity not only facilitates the permeation of Ru(bpy) within nanochannels by compressing the inner electric double layer (EDL), but also greatly improves the electron-transfer efficiency that is critical for enhanced electrochemiluminescence (ECL) generation. Therefore, the A-VMSF/ITO platform exhibited a consistent increase in ECL intensity with rising ionic strength.

Blocking Antibody Induced by Immunization with Hypoallergenic Derivatives of Scy p 1 Alleviated Mud Crab Allergy Symptoms.

Crab triggers severe IgE-mediated allergic reactions. A rabbit anti-IgG antibody induced by hypoallergenic derivatives of Scy p 1 (mtScy p 1) effectively blocked wild-type Scy p 1 (wtScy p 1) binding to serum IgE; however, its protection against allergic symptoms needs to be further studied. In this paper, rabbit anti-mtScy p 1 IgG antibody could inhibit wtScy p 1-induced basophil degranulation, mainly due to the overlap of 2 IgG conformational epitopes and 4 IgG linear epitopes with IgE epitopes.

Changes in enzyme activity and microbial community of rhizosphere soil under continuously monocultured Passiflora edulis treatment.

In response to the severe continuous cropping obstacles encountered during the cultivation of passion fruit, which leads to significant declines in yield and quality, as well as rampant pests and diseases, it is particularly important to explore strategies for mitigating these obstacles. The present study used the rhizosphere soil samples from one-year-old (FY, first-year cropping) and two-year-old (SY, second-year cropping) "Golden Passion Fruit" plants, along with soil from uncropped land (CK) as a control and the techniques such as high-throughput sequencing, qRT-PCR, and HPLC-MS to analyze the main physicochemical properties, phenolic acid content, and microbial community changes in the rhizosphere soil of passion fruit under different continuous cropping durations, the results indicated that the contents of total nitrogen, total phosphorus, available nitrogen, available phosphorus, available potassium, and organic matter in FY soil were significantly higher than those in SY soil, and the pH value of the FY soil was also significantly higher than that of SY soil. Additionally, compared with FY soil, the activities of polyphenol oxidase, peroxidase, urease, and invertase in SY soil were significantly reduced by 18.
