Bipolar electrochemistry, a phenomenon which generates an asymmetric reactivity on the surface of conductive objects in wireless manner, is important concept for many purposes, from analysis to materials science as well generation motion. Chemists have known basic long time, but it has recently attracted additional attention, especially context micro- and nanoscience. In this Account, we introduce fundamentals bipolar electrochemistry illustrate its recent applications, with particular focus...
In recent years, several experimental studies have shown that different values of single molecule conductance can be observed for the same type molecule. Although this observation has been tentatively attributed either to differing molecular conformations or contact geometries, reason groups remains still unclear. To elucidate issue, a comparison four methods measure is presented here case alkanedithiols between gold electrodes, which considered model system. Three fundamental exhibiting...
The first observation of circular polarization electrochemiluminescence (ECL) from a purely organic derivative is reported. A bispyrene scaffold mounted on constrained polyether macrocycle displaying intense excimer fluorescence and highly circularly-polarized (CP) photoluminescence has been selected for this purpose. compound displays an ECL dissymmetry factor about |8×10-3 |, which in good agreement with the corresponding value. This step towards molecular engineering tailored dyes that...
Based on the principles of bipolar electrochemistry, localized pH gradients are generated at surface conducting particles in solution. This allows toposelective deposition inorganic and organic polymer layers via a pH-triggered precipitation mechanism. Due to intrinsic symmetry breaking process, concept can be used generate straightforward way Janus particles, with one section consisting deposits obtained from non-electroactive precursors. These indirect electrodeposits, such as SiO(2),...
We present herein the combined local enzymatic sensing and dynamic ECL reporting of a glucose concentration gradient explored by bipolar swimmer.
Electrogenerated chemiluminescence is extended to the 3D by generating light at level of millions micro-emitters addressed remotely bipolar electrochemistry.
Controlling electrochemiluminescence (ECL) color(s) is crucial for many applications ranging from multiplexed bioassays to ECL microscopy.
Electrochemiluminescence (ECL) behavior of luminol derivative was investigated in reduction on different electrode materials. We found that and its widely used L-012 derivative, emitting at physiological pH values, exhibit strong cathodic ECL emission iron stainless steel electrodes with hydrogen peroxide, whereas no signal observed other classic materials (Au, Pt, C). On a Ni electrode, low observed. This points out to the essential role iron-containing enhance emission. Under reported...
Amine and carboxylic acid-bifunctionalized iron oxide nanoparticles with robust silane linkages to the nanoparticle surface were prepared a versatile direct grafting protocol. The contrast in chemistry of these two groups was highlighted by attaching fluorophore, Rhodamine B isothiocyanate (RITC) onto amine group an antibody (EPCAM – epithelial cell adhesion molecule) acid groups. core RITC tags provide MRI-fluorescent bi-modal imaging capability. EPCAM is specific protein ubiquitously...
Because electron transfer is often highly sensitive to bridge length and molecular conformation, changes in these can have a large impact on the conductance of single molecule electrical junctions. In this study, pH used control conformation effective junctions containing peptide sequence H(EL)5C (where H stands for histidine, E glutamic acid, L leucine, C cysteine). The ionizable acid residues result an oligo-peptide structure pH. At low pH, exists its more compact α-helical state, while at...
Miniaturized structures that can move in a controlled way solution and integrate various functionalities are attracting considerable attention due to the potential applications fields ranging from autonomous micromotors roving sensors. Here we introduce concept which allows, depending on their specific design, directional motion of objects water, combined with electronic such as emission light, sensing, signal conversion, treatment transmission. The approach is based electric field-induced...
The combination of enzymes, as recognition elements for specific analytes, and electrogenerated chemiluminescence (ECL) a readout method has proven to be valuable strategy sensitive analytical detection. However, ECL is intrinsically 2D process which could potentially limit the analysis inhomogeneous samples. Here, we show how bulk signal, generated by thousands carbon microbeads remotely addressed via bipolar electrochemistry, are implemented powerful tool concomitant sensing imaging two...
The redox couple resazurin-resorufin exhibits electrofluorochromic properties which are investigated herein by absorption and fluorescence spectroelectrochemistry electrochemically coupled-fluorescence confocal laser scanning microscopy (EC-CLSM). At pH 10, the highly fluorescent resorufin dye is generated at electrode surface electrochemical reduction of poorly resazurin. Performing EC-CLSM surfaces allows to monitor spatially resolved processes in situ real time. Using a small (315 μm...
