Remote‐Controlled Release of Nitric Oxide by Plasmonic Waveguide Coated With Metal–Organic Frameworks

Small, EarlyView.
Remote‐controlled intracellular delivery is achieved using a plasmonic waveguide coated with a photoresponsive NO‐releasing MOF. Surface plasmon polariton propagation remotely induces photocleavage and localized nitric oxide release in a target single live cell without direct light exposure, while biological relevance is demonstrated through transient ...

Ammonia Oxidation for Energy Conversion and Environmental Remediation: Mechanism‐Guided Catalyst Design for Electrochemical, Photocatalytic, and Photoelectrochemical Systems

Small, EarlyView.
This review establishes a mechanism‐guided framework for catalyst design in electrochemical, photocatalytic, and photoelectrochemical ammonia oxidation. By correlating catalyst structure, reaction mechanisms, catalytic performance, and device‐level architectures, it highlights rational engineering strategies and future directions toward efficient ...

A single‐molecule prodrug synergistically suppresses MYC‐amplified osteosarcoma through sequential nitric oxide release and photodynamic therapy

Smart Molecules, EarlyView.
A cascade‐responsive small‐molecule prodrug (DHU‐NO3) sequentially releases methylene blue (triggered by reactive oxygen species) and nitric oxide (controlled by 405 nm light), enabling precise spatiotemporal coordination of photodynamic therapy and NO gas therapy to effectively inhibit MYC‐amplified osteosarcoma growth.

Off‐Stoichiometric Synthesis of Porphyrin‐Based Covalent Organic Frameworks for Structural Modulation and Enhanced Chemiresistive NO2 Sensing

SusMat, EarlyView.
This study reports the sustainable synthesis of nanoscale porphyrin‐based covalent organic frameworks in aqueous solution under ambient conditions. By tuning the monomer stoichiometric ratio, defect‐rich structures are engineered within the framework, resulting in exceptional chemiresistive NO2 sensing performance, with a response of up to 7780 toward ...

Comprehensive Evaluation of Bisphenol A Toxicity Reveals Neurobehavioral, Metabolic, and Reproductive Impairments in Girardia tigrina

Environmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), a common industrial chemical used in plastics and consumer products, is increasingly detected in aquatic environments, raising serious concerns about its potential ecological impacts. This study evaluated the sublethal and acute toxic effects of BPA on the freshwater planarian Girardia tigrina, a recognized model for ...

Ecotoxicological Insights From Ex Vivo Exposure of Whole Blood to PFOS and Glyphosate: Oxidative Stress and Immune Disruption

Environmental Toxicology, EarlyView.
ABSTRACT This study investigated the immunomodulatory effects of PFOS and glyphosate (GLY), both individually and in combination, on the whole blood of three ruminant species (cow, goats, and sheep) exposed ex vivo to environmentally relevant concentrations. The research focused on key biomarkers of oxidative stress (MDA), inflammation (myeloperoxidase

Effect of nitrogen dioxide on nitrite oxidation and nitrite-oxidizing populations in soil

Soil Biology and Biochemistry, 1977
Abstract When nitrogen dioxide was added to soil at a rate equivalent to 51μg Ng −1 soil, the nitrite formed was oxidized logarithmically. The numbers of nitrite-oxidizing microorganisms also increased logarithmically, but the final count was too low to account for the amount of nitrite metabolized. In soil treated with NO 2 at a rate equivalent to

Deregulation of Ribosome Biogenesis in Nitrite-Oxidizing Bacteria Leads to Nitrite Accumulation

Environmental Science & Technology, 2023
Nitrite (NO2-) accumulation caused by nitrite-oxidizing bacteria (NOB) inhibition in nitrification is a double-edged sword, i.e., a disaster in aquatic environments but a hope for innovating nitrogen removal technology in wastewater treatment. However, little information is available regarding the molecular mechanism of NOB inhibition at the cellular ...

Photocatalytic oxidation of nitrite in water to nitrate

Environmental Pollution, 1989
It is found that the nitrite in water is converted into nitrate by irradiation in the presence of oxygen and titanium dioxide which acts as a catalyst. As nitrate is a less hazardous contaminant, this method might be worth investigating further for the treatment of water.
