We report in this paper an original way to covalently bind the macrocyclic ligand, 1,4,8,11-tetraazacyclotetradecane (cyclam), through diazonium salt chemistry, on the surface of carbon screen-printed electrodes (SPEs). The in situ synthesis of the diazonium salt obtained from the amine precursor derived from the cyclam and its electrografting are described. X-ray Photoelectron Spectroscopy was used...
We report in this paper an all-covalent method to obtain highly nanostructured carbon screen printed electrodes (SPEs) bearing gold nanoparticles (AuNPs) functionalized by complexing groups using diazonium salts chemistry. SPEs were first modified with 4-aminophenyl functions (SPE-Ph-NH2). The amino moieties were then converted into diazonium salts (SPE-Ph-N2+ Cl−). These reactive SPEs were then used...
