Web2,2,6,6-Tetramethyl-4-piperidinol (TEMP) is a spin-trap agent for electron spin resonance (ESR) that is usually employed in solution. However, in this study, TEMP is mixed with hydroxypropyl methylcellulose (HPMC) to form a film for the detection of singlet oxygen in vacuo. The ESR intensity achieved is 3.3 times higher than that for a previously reported … WebSinglet oxygen (1O2) is highly oxidative and exerts strong cytotoxic effects. We tried to establish the best combination of a singlet oxygen generation system and a detection method with ESR, for measurement of the quenching activities of various substances.

WebAntioxidant and free radical scavenging activities Inactivation of the superoxide and hydroxyl radical, and inhibition of singlet oxygen formation are two important beneficial effects of PBE. PBE was reported to exert protective effects against lipid peroxidation, thiobarbituric acid reactive products generation, and oxidative hemolysis induced ... Webdetected directly by ESR. However, the reaction of singlet oxygen with a stable molecule can generate a moderately long-lived free radical, which can then be detected by ESR. Spin-label 2,2,6,6-tetramethyl-4-piperidone (TEMP) is used as a spin-trapping probe. As shown in Fig. 3, the reaction of singlet oxygen with TEMP leads to the production ... bing.com hosts
