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.

Nanostructured artificial receptor materials with unprecedented hierarchical structure for determination of human serum albumin (HSA) are designed and fabricated. For that purpose a new hierarchical template is prepared. This template allowed for simultaneous structural control of the deposited molecularly imprinted polymer (MIP) film on three length scales. A colloidal crystal templating with optimized electrochemical polymerization of 2,3′-bithiophene enables deposition of an MIP film in the form of an inverse opal. Thickness of the deposited polymer film is precisely controlled with the number of current oscillations during potentiostatic deposition of the imprinted poly(2,3′-bithiophene) film. Prior immobilization of HSA on the colloidal crystal allows formation of molecularly imprinted cavities exclusively on the internal surface of the pores. Furthermore, all binding sites are located on the surface of the imprinted cavities at locations corresponding to positions of functional groups present on the surface of HSA molecules due to prior derivatization of HSA molecules with appropriate functional monomers. This synergistic strategy results in a material with superior recognition performance. Integration of the MIP film as a recognition unit with a sensitive extended-gate field-effect transistor (EG-FET) transducer leads to highly selective HSA determination in the femtomolar concentration range.
