Dioctylamine-Sulfonamide-Modified Carbon Nanoparticles as High Surface Area Substrates for Coenzyme Q10-Lipid Electrochemistry

Abstract:

Dioctylaminesulfonamide-modified carbon nanoparticles are characterised and employed as high surface area substrate for (i) coenzyme Q10 and (ii) 1,2-dimyristoyl-sn-glycero-3-phosphocholine (or DMPC) - Q10 redox processes. The carbon nanoparticles provide a highly hydrophobic substrate with ca. 25Fg -1 capacitance when bare. Q10 or DMPC-Q10 immobilised onto the carbon nanoparticles lower the capacitance, but give rise to well-defined pH-dependent voltammetric responses. The DMPC-Q10 deposit s...
