Highly stable dendritic trityl radicals as oxygen and pH probe.
Novel dendritic trityl radicals (DTR1 and DTR2) with a TAM radical core, PAMAM branching and carboxylate exterior surface exhibit high stability towards oxidoreductants as evidenced by their electrochemical and EPR properties, offering potential application as dual oxygen and pH probe.
متن کاملAction of ascorbic acid as a scavenger of active and stable oxygen radicals.
Free radicals attack lipids, proteins, enzymes, and DNA to cause pathological events and cancer. Ascorbic acid is one of the strongest reductants and radical scavengers and reduces stable oxygen, nitrogen, and thyl radical and acts as a primary defense against aqueous radicals in the blood. When radicals were formed in aqueous suspensions of erythrocytes or low-density lipoprotein (LDL), ascorb...
متن کاملTrityl radicals: spin labels for nanometer-distance measurements.
Spin labelling with trityls: to gather information about the structure and dynamics of trityl radicals, spin-labelled polymers were measured with pulsed electron-electron double resonance (PELDOR) and double-quantum coherence (DQC). This study demonstrates that trityl radicals have great potential as spin labels that eliminate some limitations of nitroxide spin labels.
متن کاملNanoencapsulation of perfluorinated trityl radicals and evaluation as sensors for EPR oximetry
Introduction Triarylmethyl radicals (trityls) EPR oxygen sensors are characterized by a narrow EPR Line Width (LW) and high signal to noise ratio for EPR spectra or images. Trityls are also characterized by a good in vivo half-life compared to other soluble probes (nitroxides). However, one limitation of these sensors is their very low LW variation (∆LW) compared to particular probes. Oxygen is...
متن کاملNano-emulsions of fluorinated trityl radicals as sensors for EPR oximetry.
This article reports the development and evaluation of two nano-emulsions (F45T-03/HFB and F15T-03/PFOB) containing fluorinated trityl radicals dissolved in perfluorocarbons. Preparation with a high-pressure homogenizer conferred sub-micronic size to both nano-emulsions. In vitro and in vivo EPR spectroscopy showed that the nano-emulsions had much greater oxygen sensitivity than the hydrophilic...
