Ubiquinone electrochemistry in analysis and sensing

Ubiquinone (UQ) is a lipophilic compound present in most living organisms, where UQ's interesting but complex electrochemistry serves an important role the transfer of electrons and protons within across mitochondrial membrane. We briefly review electrochemical characteristics UQ its reduced state, ubiquinol, solution immobilized on electrodes, together with application sensing detection systems, for example, measuring redox status reference to reactive oxidative species. The importance local environment, solvent, electrolyte, organic membrane, pH, behavior UQ, also discussed. discuss techniques used direct such as liquid chromatography-electrochemistry. Mediated allows quantitative measurements ions, small molecules, other analytes glucose via chemical sensors biosensors.
