Linking Glucose Oxidation to Luminol-based Electrochemiluminescence using bipolar Electrochemistry
Asymmetric Modification of TiO2 Nanofibers with Gold by Electric-Field-Assisted Photochemistry
Stimuli-responsive microgels for electrochemiluminescence amplification
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.
Our group is part of the Institute of Molecular Sciences (ISM) of the University of Bordeaux and is located at the Graduate School of Chemistry, Biology and Physics (ENSCBP). The main activities are focused on the development of new analytical tools and techniques with a special accent on miniaturized systems applied to the study of biological systems and biomedical issues. Our research addresses problems resulting from the ever increasing demands of our modern society concerning various aspects like public health, security and environmental issues.
Distinguishing molecules with almost identical physico-chemical properties, tracking their evolution with a high spatio-temporal resolution, detecting them at the cell or subcellular level in complex environments, are some of the challenges that we work on. Current projects include biofunctionalized nanoparticles, chemical sensors for Biology, electrochemistry of biosystems, micro/nanoscale imaging and smart functional nanostructures. In order to work successfully on these topics, our group is an interdisciplinary team with know-how ranging from Electrochemistry and Optics to organic or colloidal synthesis and Cell Biology. The resulting synergy is the guarantee for solutions to some of the current problems in the field of Analytical Chemistry.
