“…Organic-based electrochemical sensors use components such as DNA [ 243 , 244 ], conductive polymers [ 245 , 246 , 247 , 248 ], and organic molecules [ 249 , 250 ]. On the other hand, inorganic electrochemical methods rely on metal oxide nanoparticles [ 251 , 252 , 253 ] and carbon-based materials [ 254 , 255 ]. Among them, the most common electrochemical sensors for the detection of •OH are those in which organic elements are immobilized on an electrode surface to act as the sensing element toward •OH.…”

Reactive oxygen species (ROS) have been found in plants, mammals, and natural environmental processes. The presence of ROS in mammals has been linked to the development of severe diseases, such as diabetes, cancer, tumors, and several neurodegenerative conditions. The most common ROS involved in human health are superoxide (O2•−), hydrogen peroxide (H2O2), and hydroxyl radicals (•OH). Organic and inorganic molecules have been integrated with various methods to detect and monitor ROS for understanding the effect of their presence and concentration on diseases caused by oxidative stress. Among several techniques, fluorescence and electrochemical methods have been recently developed and employed for the detection of ROS. This literature review intends to critically discuss the development of these techniques to date, as well as their application for in vitro and in vivo ROS detection regarding free-radical-related diseases. Moreover, important insights into and further steps for using fluorescence and electrochemical methods in the detection of ROS are presented.

“…As Ce 3+ sites are responsible for the reaction with • OH, several research groups have seeked to maximize the concentration of Ce 3+ sites on CeNPs to improve their • OH scavenging capacity. 33,34 In order to minimize the size of CeNPs, and thus, maximize the amount of Ce 3+ sites for • OH scavenging and detection, we employed Surface Organometallic Chemistry (SOMC) to obtain nanosized CeO x . 35,36 We hypothesized that the size and dispersion of the CeO x nanoclusters could be adjusted by controlling the loading of the organometallic precursor.…”

To ensure a sustainable future, a tremendous range of energy conversion and storage devices including fuel cells, photovoltaics, and electrolyzers, has been developed in recent decades for the eco-friendly production and consumption of energy, without increasing CO 2 emissions. [1] The main concern about those devices for practical realization is maximizing the overall lifetime of their operation, which is largely affected by the durability of device-configuring materials under the specific operation condition for each device. In particular, soft polymeric materials are some of the key materials in those devices and are widely applied as active sites for energy conversion, charge carrier transporting media, material transporting media, etc. However, degradation of those polymeric materials in the device inevitably occurs during device operation in physical and chemical manner.
