Spectroscopies à l'échelle de la molécule individuelle : dynamique de force pour l'interaction d'oligopeptides sur or et diffusion Raman exaltée par effet de pointe sur rotaxanes, Spectroscopy on the scale of the individual molecule: dynamics of strength for the interaction of oligopeptides on gold and distribution Raman excited by state-of-the-art effect on rotaxanes

Marie Steffenhagen

Au-delà de la simple imagerie, les techniques de champ proche permettent sonder des interactions moléculaires de manière contrôlée sur un nombre réduit de molécules, voire une seule. Dans ce sujet, deux techniques de spectroscopie à sonde locale ont été mises à profit. D’une part, la spectroscopie…, Beyond simply imaging, near-field techniques allow to probe and control molecular interactions onto a reduced number of molecules, if not a single one. In this subject, we took advantage of two local-probe spectroscopies. On the one hand, dynamic force spectroscopy (AFM-DFS) was applied to measure…

Life on Minerals: Binding Behaviors of Oligonucleotides on Zirconium Silicate and its Inhibitory Activity for the Self-Cleavage of Hammerhead Ribozyme

Kunio Kawamura, Jean-François Lambert, Louis Ter-Ovanessian, Jacques Vergne, Guy Hervé, Marie-Christine Maurel

The role of minerals in the chemical evolution of RNA molecules is an important issue when considering the early stage of the Hadean Earth. In particular, the interaction between functional ribozymes and ancient minerals under simulated primitive conditions is a recent research focus. We are…

Characterizing a supported catalyst : a methodological approach

Eric Marceau

The characterization of supported catalysts requires the combination of several physicochemical and spectroscopic techniques in order to investigate the support and active phase composition, morphology and reactivity. The most common techniques used at the laboratory are detailed in this chapter…

A connective tissue is a cooperative set of differentiated cells entangled in an extracellular matrix (ECM). The latter, which is particularly abundant, is composed mainly of proteins, such as collagens, and a viscous gel made up of water and negatively charged polysaccharides: proteoglycans. All…, Un tissu conjonctif est un ensemble coopératif de cellules différenciées enchevêtrées dans une matrice extracellulaire (ECM). Cette dernière, particulièrement abondante, se compose principalement de protéines, telles que les collagènes, et d'un gel visqueux constitué d'eau et de…
