Fluorescent Detection of Reactive Oxygen Species in Saccharomyces Cerevisiae Applied to Chronological Lifespan [PDF]
, 2018 During the course of normal aerobic metabolism, cells are exposed to a wide range of reactive oxygen species such as the superoxide anion, hydrogen peroxide, and the hydroxyl radical. These reactive oxygen species (ROS) are highly reactive metabolites of

Electric Pulse Regulated MXene Based Nanozymes for Integrative Bioelectricity Immuno‐Cancer Therapy
Advanced Functional Materials, EarlyView.MXenzyme‐mediated bioelectricity cancer therapy (MXenzyme‐BECT) enhances cancer cell death through irreversible depolarization, ion channel disruption, ROS generation, and immunogenic cell death. Computational simulations reveal the electrical mechanisms by which MXenzyme acts on single cells and support to predict treatment parameters. Next‐generation
