We report here the development of coreactant-based electrogenerated chemiluminescence (ECL) as a surface-confined microscopy to image single cells and their membrane proteins. Labeling entire cell allows one demonstrate that, by contrast with fluorescence, ECL emission is only detected from fluorophores located in immediate vicinity electrode surface (i.e., 1–2 μm). Then, present potential diagnostic applications our approach, we selected carbon nanotubes (CNT)-based inkjet-printed...
Fast recombination of electrons from semiconductors with the oxidized redox species in electrolyte represents a major bottleneck improvement ZnO-based dye-sensitized solar cells (DSSCs). While processes at semiconductor-electrolyte interface are well studied on TiO2 electrodes, interactions ZnO surface solution DSSCs less explored. This work aims clarifying different impact two contrasting couples I3-/I- or [Co(bpy-pz)2]3+/2+ (bpy-pz = bis(6-(1H-pyrazol-1-yl)-2,2'-bipyridine)) electrolytes...
We describe a method to confine electrochemiluminescence (ECL) at the oil–water interface of emulsion droplets that are stabilized by luminophore-grafted microgels. These hydrogel nanoparticles incorporating covalently bound Ru(bpy)32+ as luminophore irreversibly adsorbed micrometric oil dispersed in continuous aqueous phase. study electrochemical and ECL properties this multiscale system, composed collection close contact presence two types model coreactants. emission is observed upon...
The dye regeneration in dye-sensitized solar cells (DSSCs) is improved by optimizing the charge separation at level of sensitized semiconductor treatment mesoporous electrode TiCl4 that passivates surface for back electron transfer reactions. dye-regeneration kinetics analyzed DN216- and D358-sensitized porous TiO2 electrodes with without a means scanning electrochemical microscopy (SECM). Different mass transport limitation [Co(bpy)3]3+ mediator through found comparison structurally similar...
