Reevaluation of analytical methods for photogenerated singlet oxygen
The aim of the present study is to compare different analytical methods for singlet oxygen and to discuss an appropriate way to evaluate the yield of singlet oxygen photogenerated from photosensitizers. Singlet oxygen photogenerated from rose bengal was evaluated by electron spin resonance analysis using sterically hindered amines, spectrophotometric analysis of 1,3-diphenylisobenzofuran oxidat...
متن کاملBactericidal Action of Photogenerated Singlet Oxygen from Photosensitizers Used in Plaque Disclosing Agents
BACKGROUND Photodynamic therapy (PDT) has been suggested as an efficient clinical approach for the treatment of dental plaque in the field of dental care. In PDT, once the photosensitizer is irradiated with light of a specific wavelength, it transfers the excitation energy to molecular oxygen, which gives rise to singlet oxygen. METHODOLOGY/PRINCIPAL FINDINGS Since plaque disclosing agents us...
متن کاملSinglet Oxygen
Singlet oxygen (O2) is a higher energy state molecular oxygen species. It is one of the most active intermediates involved in chemical and biochemical reactions. To fully appreciate the reactivity of O2, it is necessary to understand its physical and chemical nature. This paper reviews the generation, quenching and detection of O2. Its properties, possible chemical reactions are presented as we...
متن کاملAnalytical methods for nanomaterial characterization
In recent years, it has become evident that it is necessary to systematically and accurately define particle characteristics in order to understand the potential toxicity of nanoparticles to biological systems. The properties that need to be emphasized are size, shape, dispersion, doping, aggregation, functionalization, physical and chemical properties, surface area, and surface chemistry. Rout...
