Reaction of peroxynitrite with thiols, hydrogen sulfide and persulfides

Redox Biochemistry and Chemistry
Three decades of research on the biochemistry of peroxynitrite (ONOOH/ONOO−) have established that this stealthy oxidant is formed in biological systems, and that its main targets are carbon dioxide (CO2), metalloproteins and thiols (RSH).

Design and Functional Characterization of a Plasma‐Activated Aerosol System for Microbial Inactivation

Plasma Processes and Polymers, Volume 23, Issue 2, February 2026.
Plasma‐activated aerosol (PAA) can produce RONS‐rich droplets useful for microbial inactivation. PAA treatment induces near‐complete inactivation of both bacterial and fungal loads, highlighting peroxynitrite‐driven antimicrobial activity and strong potential for scalable sanitization.

Airborne remote sensing of nitrous acid in the troposphere: potential sources of excess HONO [PDF]

Atmospheric Chemistry and Physics
The photolysis of nitrous acid (HONO) produces hydroxyl radicals (OH), the most important cleaning agent of the troposphere. For decades, HONO has been measured in concentrations which exceed the photo-stationary concentration arising from its gas phase ...

Parameters Influencing the Plasma‐Mediated Inactivation of Microorganisms and Viruses in Wastewater

Plasma Processes and Polymers, Volume 23, Issue 2, February 2026.
Wastewater parameters, e.g., chemical oxygen demand (COD), influences the antimicrobial and antiviral efficacy of plasma. ABSTRACT Pathogenic microorganisms and viruses in water pose an environmental risk demanding for effective remediation tools like physical plasma. However, parameters influencing its efficiency are mostly descriptive.

Therapeutic Potential of Melatonin in Gastrointestinal Cancers: Molecular Mechanisms, Preclinical Evidence and Clinical Implications

Journal of Pineal Research, Volume 78, Issue 1, January 2026.
ABSTRACT Gastrointestinal (GI) cancers remain a leading cause of global morbidity and mortality, necessitating novel therapeutic strategies. Melatonin (MEL), an indoleamine with pleiotropic biological activities, has emerged as a promising adjuvant in oncology due to its antiproliferative, proapoptotic, and antioxidant properties.

A guide to reactive oxygen species in tumour hypoxia: measurement and therapeutic implications

Molecular Oncology, Volume 19, Issue 11, Page 3003-3022, November 2025.
Hypoxia reshapes tumour redox landscapes by altering compartmental ROS production (mitochondria, NOX, ER, peroxisomes). Accurate interpretation requires oxygen‐contextualised measurement (live biosensors, chemical probes, EPR, LC–MS) and awareness of artefacts (reoxygenation, probe specificity).
