Miniaturized Pathogen Detection System Using Magnetic Nanoparticles and Microfluidics Technology

Benjamin Garlan, Amine Rabehi, Kieu Ngo, Sophie Neveu, Reza Askari Moghadam, Hamid Kokabi

Rapid detection of a biological agent is essential to anticipate a threat to the protection of biodiversity and ecosystems. Our goal is to miniaturize a magnetic pathogen detection system in order to fabricate an efficient and portable system. The detection device is based on flat, multilayer coils…

Role of Hydroxyl Groups in the Basic Reactivity of MgO : a Theoretical and Experimental Study

Céline Chizallet, Guylène Costentin, Hélène Lauron-Pernot, Jean Marc Krafft, Philippe Bazin, Jacques Saussey, Françoise Delbecq, Philippe Sautet, Michel Che

Clean (i.e., carbonate- and hydroxyl-free) and hydroxylated MgO surfaces of various morphologies were used to study the correlation between thermodynamic Brønsted basicity (evaluated by the deprotonation of methanol and propyne followed by FTIR) and basic reactivity (evaluated by the conversion of…

Quantitative Investigation of MgO Bronsted Basicity: DFT, IR, and Calorimetry Study of Methanol Adsorption

Hugo Petitjean, Konstantin Tarasov, Francoise Delbecq, Philippe Sautet, Jean-Marc Krafft, Philippe Bazin, Maria Cristina Paganini, Elio Giamello, Michel Che, Helene Lauron-Pernot, Guylene Costentin

The adsorption geometries, energies, and vibrational frequencies of methanol on MgO defective surfaces have been calcd. by periodic DFT simulations. The results are very comparable with those obtained with water and are also in very good accordance with microcalorimetry and IR expts. At low…

Biosensors elaborated on gold nanoparticles, a PM-IRRAS characterisation of the IgG binding efficiency.

Anne-Laure Morel, Souhir Boujday, Christophe Méthivier, Jean-Marc Krafft, Claire-Marie Pradier

This work is focused on studying the grafting of gold nanoparticles (Np) on a cystamine self-assembled monolayer on gold, in order to build sensitive immunosensors. The synthesis and deposition of gold nanoparticles, 13 and 55 nm sizes, were characterised by combining Polarisation Modulation…

A combined EXAFS and DFT study of the Ni2+ environment in dehydrated Ni/NaX

Hazar Guesmi, Pascale Massiani

The location of the divalent nickel cation exchanged in low amount in dehydrated NaX is identified by a combination of experimental (XAS) and theoretical (DFT) approaches. The Ni-O and Ni-T distances as well as the coordination numbers evaluated from experiments are in good agreement with the…
