The structural and the photoelectrochemical properties of ZnO–ZnS/ITO 1D hetero-junctions prepared by tandem electrodeposition and surface sulfidation: on the material processing limits

A. Brayek, S. Chaguetmi, M. Ghoul, I. Ben Assaker, R. Chtourou, P. Decorse, P. Beaunier, S. Nowak, F. Mammeri, S. Ammar

ZnO–ZnS 1D hetero-nanostructures were prepared by an easy and scalable processing route. It consists of ZnO nanorod electrodeposition on ITO substrate and surface sulfidation by ion exchange in an aqueous Na 2 S solution. Increasing the treatment contact time (t c) from 8 to 48 h involves different…

Nanostructured and spiky gold in biomolecule detection: improving binding efficiencies and enhancing optical signals

E. E. Bedford, S. Boujday, C.-M. Pradier, F. X. Gu

Nanostructured gold can improve the ability to detect biomolecules. Whether planar nanostructured surfaces or nanostructured particles are used, similar principles governing the enhancement apply. The two main benefits of nanostructured gold are improved geometry and enhancement of optical…

Fischer carbene mediated covalent grafting of a peptide nucleic acid on gold surfaces and IR optical detection of DNA hybridization with a transition metalcarbonyl label

Pratima Srivastava, Mahsa Ghasemi, Namrata Ray, Amitabha Sarkar, Jana Kocabova, Stepanka Lachmanova, Magdalena Hromadova, Souhir Boujday, Silvia Cauteruccio, Emanuela Licandro, Pramod Thakare, Céline Fosse, Michèle Salmain

Amine-reactive surfaces comprising N-hydroxysuccinimide ester groups as well as much more unusual Fischer alkoxymetallocarbene groups were generated on gold-coated surfaces via self-assembled monolayers of carboxy- and azido-terminated thiolates, respectively. These functions were further used to…
