这种基于铂金属元素（Os）设计的人工酶，具有强大的电子传输能力和高度暴露的活性位点，可以有效地在肿瘤微环境（TME）的酸性环境中催化过氧化氢（H2O2）生成ROS。在低强度超声辐照的作用下，这一催化过程被显著放大，所产生的ROS不仅能够破坏肿瘤细胞的 ...

Reactive Oxygen Species (ROS): Chemically reactive molecules containing oxygen, which can lead to cellular damage if not regulated. Excited-State Intramolecular Proton Transfer (ESIPT): A ...

Among them, reactive oxygen species (ROS) are key regulators and play pivotal roles during plant stress responses. ROS such as hydrogen peroxide (H2O2), superoxide anions (O2−.), hydroxyl radical (OH− ...

To examine ROS during tail regeneration, they measured the level of H2O2 (hydrogen peroxide, a common reactive oxygen species in cells) using a fluorescent molecule that changes light emission ...

However, they also produce reactive oxygen species (ROS), which are molecules ... researchers to monitor oxygen consumption and hydrogen peroxide release from mitochondria in real-time.

Abstract: We studied the cytoprotective effect of triphlorethol-A against γ-ray radiation- induced oxidative stress. In this study, hydrogen peroxide, which is a reactive oxygen species (ROS), was ...

Plant cellular metabolism is continuously producing ROS such as superoxide anion radical (O2•–), hydrogen peroxide (H2O2), and singlet oxygen (1O2) at basal levels that are incapable to cause damage, ...

The ROS (reactive oxygen species), which is generated from hydrogen peroxide can lead to lipid peroxidation. It is a chain reaction, which can damage cell membranes, disrupt membrane integrity ...
