A multimode fiber-based sensor is proposed and demonstrated for the detection of lead traces in contaminated water. The sensing mechanism involves using a light sheet to excite a specific group of skew rays that optimizes light absorption. The sensing region features an inline microbubble structure that funnels the skew rays into a tight ring, thereby intensifying the evanescent field.

Methods: Comprehensive bioinformatics tools were used to screen hub genes in castration-resistant prostate cancer and were verified in androgen-dependent prostate cancer and castration-resistant prostate cancer in TCGA and the SU2C/PCF Dream Team database, respectively.
Nanomaterial-derived quantum dots (QDs) are excellent electrochemiluminescence (ECL) luminophores and play an important role in optical sensing due to their excellent water solubility, good biocompatibility and tunable molecular size. In this work, a novel strategy was designed to form nano-hybrid TiC QDs-AuNPs in situ as a luminophore based on the unique reducibility of TiC QDs, which showed remarkable and stable ECL performance. Here, AuNPs were formed in situ without the addition of reducing agents and stabilizers, leading to threefold enhancement of the ECL signal of TiC QDs due to their excellent charge transfer capability.

Patients And Methods: Patients with pathologically confirmed stage IIA‒IVA ESCC were randomized 1:1 to receive conventional fractionated 60 Gy or 50 Gy to the tumor and regional lymph nodes. Concurrent weekly chemotherapy (docetaxel 25 mg/m2; cisplatin 25 mg/m2) and two cycles of consolidation chemotherapy (docetaxel 70 mg/m2; cisplatin 25 mg/m2 days 1‒3) were administered.
Electrochemiluminescence (ECL) is a powerful readout method for the development of (bio)sensors, whose performances depend on the electrode materials and the architecture of its surface. Herein, we demonstrate that the precise control of the sensing interface using the versatility of two-dimensional (2D) transition metal carbides (TiCT MXene) leads to the enhancement of the ECL signal. This electrode material, which exhibits remarkable structural and electrochemical properties was decorated by the in situ formation of gold nanoparticles (AuNPs) owing to the Ti reducibility.

In this work, we studied three rice genotypes (T-35, RZ-1, and RZ-2) to quantify the diverse PTE effects and tolerances by examining morphology, physiology, and DNA methylation patterns. Morphological results showed that T-35 exhibits the highest tolerance to all studied PTE stressors (Cu, Cd, Cr).

Biomedical implants-associated bacterial infections have become a major threat to human health. Therefore, it is meaningful to develop new antibacterial strategies to solve this problem. In this study, we conjugated acetylated lentinan (AceLNT) with α-terpineol (AceLNT-g-α-ter), a highly effective natural antibacterial compound, to constitute a novel AceLNT-g-α-ter membrane (AceLNT-g-α-terM).

Herein, TiC with rich Ti vacancy defects was used as reducing agent, and Au NPs were generated in situ and anchored on the TiC (Au NPs-TiC). Moreover, the Au NPs-TiC composites were used as a carrier and provided a large number of sites for the efficient linking of luminol through Au-N bonds to form stable luminol-Au NPs-TiC.

To improve the loading and delivery for hydrophobic drugs and optimize the release efficiency in tumor microenvironment, a novel core-shell magnetic micro-organogel carrier was successfully prepared by a sono-catalysis process in the study. As-synthesized magnetic micro-organogel had an appropriate dispersibility in water owing to the hydrophilicity of protein shell and could be kept steadily with a well-defined spherical morphology owing to the three-dimensional gel structure of oil core, and it promised an accessible targeted drug delivery owing to its good magnetism-mediated motion ability. Moreover, the magnetic micro-organogel showed a high loading efficiency up to 94.
