Caractérisations par microscopie, spectroscopie et électrochimie d'un biofilm à partir d'une eau potable sur acier inoxydable

Jean Gamby, Alain Pailleret, C. Boucher, Claire Marie Pradier, Bernard Tribollet

Nous avons suivi la formation d’un biofilm sur l’acier inoxydable (AISI 316) immergé dans un circuit d’eau potable pour deux températures (20 ◦C et 37 ◦C à pH = 8,25 – 8,5), à l’aide de techniques de caractérisation par spectroscopies : PM-IRAS (infrarouge de surface), XPS (spectroscopie des…, Microscopic, spectroscopic and electrochemical methods to investigate development of potable water biofilms on stainless substrate. We studied biofilm formation on stainless steel occurring in a drinking water distribution system which operated at two different temperature (20 ◦C and 37 ◦C at pH =…

Polyoxometalate nanostructured gold surfaces for sensitive biosensing of benzo[a]pyrene

Dimitri Mercier, Maroua Ben Haddada, Maria Huebner, Dietmar Knopp, Reinhard Niessner, Michèle Salmain, Anna Proust, Souhir Boujday

We report the design of a polyoxometalate-nanostructured immunosensor for benzo[a]pyrene (B[a]P) detection. The organic–inorganic hybrid polyoxometalate (POM) (NBu4)3[PW11O39{(SiC6H4NH2)2O}] carrying two amine functions was covalently attached to a functionalized gold substrate to achieve a…

Gold nanoparticle-based localized surface plasmon immunosensor for staphylococcal enterotoxin A (SEA) detection

Maroua Ben Haddada, David Hu, Michèle Salmain, Lu Zhang, Chen Peng, Yi Wang, Bo Liedberg, Souhir Boujday

We describe the engineering of stable gold nanoparticle (AuNP) bioconjugates for the detection of staphylococcal enterotoxin A (SEA) using localized surface plasmon resonance (LSPR). Two types of AuNP bioconjugates were prepared by covalently attaching anti-SEA antibody (Ab) or SEA to AuNPs. This…

Insights into OCP Identification and Quantification in the Context of Apatite Biomineralization

Marc Robin, Stanislaw von Euw, Guillaume Renaudin, Sandrine Gomes, Jean-Marc Krafft, Nadine Nassif, Thierry Azaïs, Guylene Costentin

Calcium phosphates (CaPs) are one of the major mineral families of wide interest in biomineralization and biomaterial development. The identification and quantification of the different CaP phases (crystalline and amorphous) remains a major challenge in both in vitro and in vivo systems. This work…

Mechanical properties of nanostructured films with an ultralow volume fraction of hard phase

Marion Chenal, Cyril Véchambre, J.-M. Chenal, Laurent Chazeau, Vincent Humblot, Laurent Bouteiller, Costantino Creton, Jutta Rieger

We demonstrate in this paper how polymerization induced self-assembly (PISA) using RAFT can be used to synthesize very asymmetric but monodisperse poly(acrylic acid)-b-poly(n-butyl acrylate) block copolymers, PAA-b-PBA, with a short PAA block and a long PBA block. In the course of the surfactant-…

Jolanda Spadavecchia, Ramesh Perumal, Alexandre Barras, Joël Lyskawa, Patrice Woisel, William Laure, Claire-Marie Pradier, Rabah Boukherroub, Sabine Szunerits

We show in this article that doxorubicin-modified gold nanoparticles (Au NP-DOX) can be used for the post-amplification of the wavelength shift of localized surface plasmon resonance (LSPR) signals after DNA hybridization events. We take advantage of the intercalation properties of DOX with guanine…
