Abstract
Multifunctional nanoparticles (NPs) that consist of silica-coated magnetic cores and luminescent ruthenium(II) polypyridine complexes have been prepared. These multifunctional nanocomposites were shown to exhibit superparamagnetic behavior, high emission intensity, and electrochemiluminescence. An intense low-oxidation-potential electrochemiluminescence signal was observed by attachment of these functional NPs onto a fluorosurfactant-modified gold (Au(m)) electrode via application of an external magnetic field.
