Methods to Unravel Pathways of Reactive Oxygen Species in the Photodynamic Inactivation of Bacteriams. Here, we describe the effect of the media and the addition of ROS scavengers to obtain insight about the oxidative processes that take place during the photokilling of bacteria. In addition, 9,10-dimethylanthracene was used to sense the generation of singlet molecular oxygen, O.(.Δ.), in microbi

EPR Spectroscopy as a Method for ROS Quantification in the Skin,an life as it stimulates vitamin D synthesis and well-being. However, an excessive dose of solar radiation leads to the formation of free radicals. Here, we describe an EPR method for measuring the amount of radicals induced by UVA irradiation in excised skin. For the first time, a wavelength stable

Detection of Superoxide Radical in Adherent Living Cells by Electron Paramagnetic Resonance (EPR) Sradicals, such as superoxide and hydroxyl radicals, in living cells. Detection is usually performed on cell suspensions introduced in glass capillaries, gas-permeable tubing, or flat cells, even when cells normally require attachment for growth. However, radical production may be influenced by cell

A General Method to Establish the Relative Efficiency of Different Sonosensitizers to Generate ROS is the use of specific ROS inhibitors. We present a general method to establish the relative efficiency of different sonosensitizers which produce the same ROS. To demonstrate it, we use peroxides as sonosensitizers which produce singlet molecular oxygen. The method is easily generalized by all type

Lipid Peroxidation Assay Using BODIPY-Phenylbutadiene Probes: A Methodological Overview,uction of cell damage at low and high concentrations, respectively. Detection of lipid peroxidation with sensing probes such as some BODIPY dyes has now wide application in studies using fluorescent microplate readers, flow cytometry, and fluorescence microscopy. Two phenylbutadiene derivatives of B

The Use of Fluorescent Probes to Detect ROS in Photodynamic Therapy,ty of reactive oxygen species (ROS) by an interaction between the long-lived PS triplet states with ambient oxygen. The most important type of ROS in photodynamic therapy (PDT) is singlet oxygen, which is produced by a Type II energy transfer process. On the other hand, superoxide, hydrogen peroxide

The Use of Fluorescent Probes to Detect ROS in Photodynamic Therapy,tease apart these different ROS produced when various PS are illuminated in solution. Singlet oxygen sensor green (SOSG) is used for singlet oxygen, 4-hydroxyphenyl-fluorescein (HPF) for hydroxyl radicals, Amplex Red for hydrogen peroxide, and nitroblue-tetrazolium or XTT for superoxide.
