PDA@CeMn nanozyme for enhanced myocardial protection via ROS scavenging and inflammation suppression
摘要
The mortality rate of cardiovascular diseases (CVD) remains alarmingly high. Studies have shown that reactive oxygen species (ROS)-mediated inflammatory responses and oxidative stress are key pathological mechanisms driving CVD. Nanozymes, nanomaterials with enzyme-like activities, offer several advantages over natural enzymes, including enhanced stability and scalability. Previous research has demonstrated that nanozymes containing cerium (Ce) or manganese (Mn) possess excellent ROS-scavenging capabilities. Dopamine, a positive inotropic agent commonly used in clinical practice to improve cardiac function in patients with heart failure, has also been shown to self.
