Multiple enhancement of luminol electrochemiluminescence using electrodes functionalized with titania nanotubes and platinum black: ultrasensitive determination of hydrogen peroxide, resveratrol, and dopamine

Synthesis, characterization and photoluminescence properties of Tm3+-doped Ca2YTaO6 blue-emitting phosphors

“…Ttantalates enjoy the merits of excellent chemical and physical stability, which have drawn widespread attention in the synthesis of phosphors. Recently, Eu 3+ , Sm 3+ , Dy 3+ , and Mn 4+ doped Ca 2 YTaO 6 phosphors were proved to be well applied in the WLED applications [14,15] [16][17][18][19]. In this work, Ca 2 YTaO 6 :Tm 3+ phosphors were firstly synthesized through solid-state reaction (at 1550 °C, in air condition).…”

Deciphering the Platinized Surface Reactivity to Improve the Detection of Hydrogen Peroxide in Bioanalyses

“…[25][26][27][28][29] In general, the great sensitivity achieved by these biosensors is explained by both the roughness, and consequently high surface-area of the Pt-black deposits, and the catalytic activityo ft his materialt oward the electro-oxidation of H 2 O 2 . [30][31][32] Surprisingly,t hought he mechanism of this reaction has been extensively studied on polycrystalline platinum electrodes, [33][34][35][36][37][38][39] little is known about what happensexactly on Pt-blacka nd which features provide specific activity to this surface.…”

“…The good compatibility between Pt‐black surfaces and biological systems has been illustrated by the incorporation of this material in the construction of implantable electrodes and in the fabrication of numerous biosensors, among which glucose biosensors occupy an important part . In general, the great sensitivity achieved by these biosensors is explained by both the roughness, and consequently high surface‐area of the Pt‐black deposits, and the catalytic activity of this material toward the electro‐oxidation of H 2 O 2 . Surprisingly, though the mechanism of this reaction has been extensively studied on polycrystalline platinum electrodes, little is known about what happens exactly on Pt‐black and which features provide specific activity to this surface.…”

A New Tactic for Label-Free Recognition of β-Trophin via Electrochemiluminescent Signalling on an AuNPs Supported Immuno-Interface

“…To understand this case, another possible factor emerges as a clue. Indeed, there is a bypass reaction of oxygen that would influence the sensing performance 49 , 50 . We can see from route “a” in Fig.…”
