Amplified plasmonic detection of DNA hybridization using doxorubicin-capped gold particles

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…

Targeted polyethylene glycol gold nanoparticles for the treatment of pancreatic cancer: from synthesis to proof-of-concept in vitro studies

Jolanda Spadavecchia, Dania Movia, Caroline Moore, Ciaran Manus Maguire, Hanane Moustaoui, Sandra Casale, Yuri Volkov, Adriele Prina-Mello

The main objective of this study was to optimize and characterize a drug delivery carrier for doxorubicin, intended to be intravenously administered, capable of improving the therapeutic index of the chemotherapeutic agent itself, and aimed at the treatment of pancreatic cancer. In light of this…

Polyethylene glycol Gold-Nanoparticles: Facile Nanostructuration of Doxorubicin and its complex with DNA molecules for SERS detection

Jolanda Spadavecchia, Ramesh Perumal, Sandra Casale, Jean-Marc Krafft, Christophe Methivier, Claire-Marie Pradier

We report the synthesis of dicarboxylic acid-terminated polyethylene-glycol (PEG)-gold nanoparticles by a simple one-step method, and their further use to form nanostructured surfaces for biomolecule immobilization. The synthesized nano-scale particles were conjugated with probe/target…

Chimie : un vecteur vert

Jacques Maddaluno, Claire-Marie Pradier, Anne Imberty, Dominique Massiot

Les faits, longtemps sujets à discussion, sont désormais là. Le cinquième rapport du GIEC (2013) qualifie d'« extrêmement probable » un lien entre les dérèglements climatiques observés depuis 1950 et les variations de la composition de l'atmosphère terrestre provoqués par l'…

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…

Biomineralization Patterns of Intracellular Carbonatogenesis in Cyanobacteria: Molecular Hypotheses

Jinhua Li, Isabel Margaret-Oliver, Nithavong Cam, Thomas Boudier, Marine Blondeau, Eric Leroy, Julie Cosmidis, Feriel Skouri-Panet, Jean-Michel Guigner, Céline Férard, Melanie Poinsot, David Moreira, Purificacion Lopez-Garcia, Corinne Cassier-Chauvat, Franck Chauvat, Karim Benzerara

The recent discovery of intracellular carbonatogenesis in several cyanobacteria species has challenged the traditional view that this process was extracellular and not controlled. However, a detailed analysis of the size distribution, chemical composition and 3-D-arrangement of carbonates in these…

A combined experimental and theoretical study of the simultaneous occupation of SIa and SI0 sites in fully dehydrated K-LSX

Hazar Guesmi, Pascale Massiani, Habiba Nouali, Jean-Louis Paillaud

In the case of fully potassium exchanged X and LSX faujasites, it was reported from a single crystal X-ray study on zeolite X and preliminary powder X-ray diffraction (PXRD) study on zeolite LSX that K+ ions can be found concomitantly in both sites I and I' with partial or full occupancy of…

Electrostatic interactions at the nanoscale can lead to novel properties and functionalities that bulk materials and devices do not have. Here we used Kelvin probe force microscopy (KPFM) to study the work function (WF) of gold nanoparticles (NPs) deposited on a Si wafer covered by a monolayer of…
