How far can hydroxyl radicals travel? An electrochemical study based on a DNA mediated electron transfer process.

چکیده
Using photocatalytic reactive nanoparticles and DNA composite modified gold electrodes, exploiting the sensitivity of DNA-mediated electron transfer to base pair stacking, we examined the effects of DNA oxidation damage by photocatalytically generated hydroxyl radicals (˙OH) on charge transfer efficiency and proposed an electrochemical technique to read the effective diffusing distance of ˙OH.

Selective and sensitive determination of hydroxyl radicals generated from living cells through an electrochemical impedance method.
An efficient protocol for selective and sensitive detection of generated hydroxyl radicals was first developed in the photocatalytic system through an electrochemical impedance method and further successfully applied to monitor hydroxyl radicals in the LPS-mediated cellular ROS/RNS burst process.
متن کاملUsing an electrochemical nanobiosensor based on titanium carbide-carbon nanotubes polymeric nanocomposite for the epithelialovarian cancer early detection
Background & Aim: Ovarian cancer is the most lethal among female malignancies. So far, treatment improvements have affected patient survival, but it is still more important to provide an early diagnosis that can detect the disease in its early stages. Therefore, introducing a rapid, accurate, and low-cost method to disease detection can be important and necessary. Methods: This study introduce...
متن کاملKinetics and Mechanism of Trithionate and Tetrathionate Oxidation at Low pH by Hydroxyl Radicals
The oxidation kinetics of trithionate (S3O 2− 6 ) and tetrathionate (S4O 2− 6 ) with hydroxyl radicals (OH∗) have been investigated in systems analogous to acid mine drainage (AMD) environments. The discovery of hydroxyl radical (OH∗) formation on pyrite surfaces (Borda et al., 2003) suggests hydroxyl radicals may affect the oxidation kinetics of intermediate sulfur species such as tetrathionat...
متن کاملTreatment of Aqueous Solution Containing Acid red 14 using an Electro Peroxone Process and a Box-Behnken Experimental Design
Background & Aims of the Study: Azo dyes utilized in industrial processes, such as the textile manufacturing, lead to the creation of huge amounts of colored wastewaters that contain non-organic and organic constituents. Therefore, it is necessary to search for remedies in this regard. This study investigated the degradation and mineralization of Acid red 14 (AR14), which is a mono Azo dye gene...
متن کاملFree radical scavenging, DNA protection, and inhibition of lipid peroxidation mediated by uric acid.
Uric acid (UA) has been proposed to be the dominant antioxidant in birds. The objective of this study was to investigate the quenching effect of varying concentrations of UA, including those found in avian plasma, on specific reactive oxygen species (ROS) and to determine the ability of UA to protect DNA and cellular membranes from ROS-mediated damage. Hydroxyl (OH) and superoxide (O2-) radical...
