A non-invasive way of detecting measurable, low levels of hydrogen peroxide and other ROS to provide a viable way to detect inflammation
Inflammation is the hallmark of many human diseases, from infection to neurodegeneration. The chemical balance within a tissue is disturbed, resulting in the accumulation of reactive oxygen species (ROS) such as hydrogen peroxide, which can cause oxidative stress and associated toxic effects.
Although some ROS are important in cell signaling and the body’s defense mechanisms, these chemicals also contribute to and are indicators of many diseases, including cardiovascular dysfunction. A non-invasive way of detecting measurable, low levels of hydrogen peroxide and other ROS would provide a viable way to detect inflammation. Such a method would also provide a way to selectively deliver drugs to their targets.
Adah Almutairi, PhD, associate professor at the Skaggs School of Pharmacy and Pharmaceutical Sciences, the Department of NanoEngineering, and the Materials Science and Engineering Program at the University of California, San Diego, and colleagues have developed the first degradable polymer that is extremely sensitive to low but biologically relevant concentrations of hydrogen peroxide.
