Intensification of the electrochemiluminescence of luminol on hollow TiO2 nanoshell-modified indium tin oxide electrodes

The electrochemiluminescence of luminol on titania nanotubes functionalised indium tin oxide glass for flow injection analysis

“…Currently, several nanostructured TiO 2 materials, such as nanotubes, arrayed nanotubes, nanobelts, nanowires and nanorods, have been synthesised for a lot of important research fields [17][18][19][20] because of their better performance than artless titania nano-particles (TiO 2 NPs). We have also synthesised the hollow-shells of nano-titania (TNHSs), and affirmed its better efficiency than TiO 2 NPs by improved light transparence [21], reaching the level of those nano-composites, such as nano-titania hybrids of Au or AuAg [14,15]. Nevertheless, the synthesis of TNHSs is very complex, difficult and low yielding.…”

Progress of the Electrochemiluminescence Biosensing Strategy for Clinical Diagnosis with Luminol as the Sensing Probe

“…Also a reagentless ECL electrode has been designed with luminol‐aniline co‐polymer as luminophore on nano‐TiO 2 functionalized ITO by means of cyclic voltammetry for utilizing as sensing matrix . Hollowed titania nanoshells, which were synthesized by a SiO 2 sacrificial template method, titania nanotubes, and Au decorated nano‐titania, have also been applied to enhance the ECL of luminol. Thereafter the nano‐titania supported AuAg alloy NCs had been immobilized onto ITO working electrode, the intensification of AuAg and PtAg alloy NCs on the ECL of luminol has been also investigated .…”

Enhanced Electrochemiluminescence of Luminol on Indium Tin Oxide Modified with Dendrimer‐Encapsulated Au Nanoparticles

“…The use of nanomaterials in luminol ECL‐based analyses has been suggested in order to intensify the ECL intensity of luminol and thus to enhance sensitivity further in the analyses 14–16. Of all the suggested nanomaterials, the use of nanoparticles has been particularly interesting due to the unique benefits of nanoparticles, such as high surface area‐to‐volume ratio and electrocatalytic activity 17, 18.…”
