Advances in the Scavenging Materials for Reactive Oxygen Species

Life obtains oxygen from breathing, which further oxidizes carbohydrates and acquires energy in mitochondria to support life processes. However, in the process of oxidation, highly reactive oxygen species (ROS) will be generated. When the human bodies lose its control on ROS, its concentration will be greatly increased, causing oxidative stress and irreversible damage to the body, thus resulting in aging, tumor, cardiovascular and neurological diseases, etc. Antioxidants are the core substances that resist ROS, and control the oxidative stress and protect the body from being damaged. In this paper, we briefly review the research progress on the scavenging materials for ROS in recent years, and see a pyramidic structure with three levels on the design of related scavenging materials. The design of nano-hybrid free radical scavenger might not only solve the toxicity problem of inorganic nanoparticles, but also afford the system with the additional functions. Hopefully, this review may enlighten some clues for the people working in the area to design highly functional ROS scavenger materials with high performances.
