Electropolymerization of Polypyrrole by Bipolar Electrochemistry in an Ionic Liquid
In our last paper published in Langmuir, pyrrole has been electropolymerized on a bipolar electrode - either in ionic liquid or in acetonitrile - and the resulting polymer films were characterized by Scanning Electron Microscopy and by contact profilometry.
A new tool for Transfer of Technology
Launched in last January, the BrivaTech cluster is your privileged interlocutor if you are interested in using some of the technologies developed in the NSysA research group.
Site-Selective Synthesis of Janus-type Metal-Organic Framework Composites
Bipolar electrochemistry is applied in a straightforward way to the site-selective in situ synthesis of metal–organic framework structures. The novelty of the presented work is that the deposit can be intentionally confined to a defined area of a substrate without using masks or templates.
Electrochemistry of Biosystems
Part of our research activities are devoted to the development of sensors and methodologies for the detection of biological activities in order to elucidate with biologists and clinicians fundamental metabolic or genetic mechanisms.
Mapping the Electrogenerated Chemiluminescence Reactivity in Space: Mechanistic Insight into Model Systems Used in Immunoassays
The remarkable characteristics of electrogenerated chemiluminescence (ECL) as a readout method are successfully exploited in microbead-based immunoassays.
Straight-forward Synthesis of Ringed Particles
Here, we report the straightforward chemical synthesis of complex metallic ring structures on the surface of spherical particles using an original template-free bulk process.
Impact of pNIPAM Microgel Size on their Ability to stabilize Pickering Emulsions
In this Langmuir publication, we studied the influence of the particle size on the ability of poly(N-isoprolylacrylamide) microgels to stabilize direct oil-in-water Pickering emulsions. The microgel size wass varied from 250 to 760 nm, the cross-linking density being kept constant.
Here, we describe a new aspect of multicolor potential-resolved electrochemiluminescence (ECL) based on bipolar electrochemistry (BPE). BPE involves a potential gradient established along a polarized conducting object which thus acts as a bipolar electrode (BE). The resulting driving forces can induce electron-transfer reactions, necessary for processes such as ECL occurring at different longitudinal locations along the same BE. In this work, we exploit the entire spatial domain where anodic polarization occurs to demonstrate for the first time how the potential gradient along a BE may be used to simultaneously resolve the emissions of ECL-active luminophores with differing oxidation potentials. The control of both size and position of the ECL-emitting domains was achieved by tuning the applied electric field. Multicolor light-emission was analyzed in detail to demonstrate spatial and spectral resolution of a solution containing different emitters.
