Summary: This study provides the first direct evidence of neurotoxicity induced by nanoplastics, using single-vesicle electrochemistry. The researchers observed cellular uptake of polystyrene nanoplastics, leading to cell viability loss and reductions in vesicular catecholamine content, exocytotic activity, neurotransmitter release, and fusion pore opening-closing speed. Mechanistic investigations suggest that nanoplastics disrupt F-actin assemblies. This research offers important insights into how nanoplastics affect neurotransmitter secretion and neural functions.

Summary: In recent years, photocatalytic reactions using graphitic carbon nitride (g-C3N4) as the catalyst and enzyme-catalyzed degradation using horseradish peroxidase (HRP) have shown great potential in degrading organic pollutants. The coupling effect of g-C3N4 and HRP improves the efficiency of carrier separation and generates more active species, leading to the solar-driven non-selective destruction of organic pollutants. This study provides a detailed description of the alteration of g-C3N4 and the immobilization of HRP, and outlines recent developments in the photo-enzyme coupling of g-C3N4 and HRP.

Summary: In this study, hydrogel films of poly(N,N-diethylacrylamide) (PDEA) were synthesized on glassy carbon (GC) electrodes to investigate the switchable electrochemical behavior of isoniazid (INH), an electroactive pharmaceutical molecule. The electrochemical response of INH on PDEA-modified electrodes was found to be sensitive to pH, temperature, and salt concentration, leading to the design and construction of a 3-input/8-output combinational pharmaceutical logic gate network and a 3-to-8 decoder. Furthermore, the relationship between the oxidation peak current (Ipa) and INH concentration (CINH) was studied using differential pulse voltammetry (DPV). This research provides a new approach and model for designing drug sensors and has potential applications in intelligent medical diagnostics and drug release.

Summary: The development of low-cost and high-efficiency iodine sorbents is essential for nuclear pollution control. In this study, we intercalated the tin sulfide cluster of [Sn2S6](4-) into Mg/Al-type layered double hydroxides to obtain Sn2S6-LDH, which exhibited highly efficient capture performance for iodine in both vapor and solution forms. The adsorption capacity of Sn2S6-LDH for iodine vapor reached 2954 mg/g, mainly through physisorption, while the sorption capacity for iodine in solutions achieved a significantly large value of 1308 mg/g. During iodine capture, the reduction of I-2 molecules to I- ions by S2- in [Sn2S6](4-) led to the formation of SnI4, where the amount of captured iodine was four times that of Sn. The excellent iodine capture capability of Sn2S6-LDH makes it a promising material for trapping radioactive iodine.

Summary: In this study, Cd-doped Ni3S2 nanosheet arrays were fabricated via a hydrothermal strategy and Cd/Ni ratio tuning. The optimized Cd-Ni3S2/NF-1/4 exhibited the best electrocatalytic performance for water splitting, requiring ultralow overpotentials for both the hydrogen evolution reaction and oxygen evolution reaction. Furthermore, the Cd-doped Ni3S2 demonstrated improved overall water splitting performance due to enhanced electroconductivity and active sites accessibility. This work provides an effective strategy for the fabrication of highly efficient bifunctional electrocatalysts for hydrogen production.

Summary: Radiotherapy (RT) is widely used in clinics and has advantages like strong penetration, high energy intensity, and low systemic side effects. However, tumor hypoxia during RT significantly reduces its therapeutic effect. Tumor hypoxia, a common characteristic of locally advanced solid tumors, promotes tumor cell proliferation, invasion, and metastasis. In recent years, the use of biocatalytic nanomaterials (BCNs) to reverse tumor hypoxia during RT has been explored. This review focuses on oxygen-generating BCNs and their potential in relieving tumor hypoxia in RT. The classification, engineering nanocatalytical activity of oxygen-generating BCNs, and combination therapy based on these BCNs are discussed. The challenges and prospects of using oxygen-generating BCNs in RT applications are summarized.
