Observation of Oscillatory Surface Reactions of Riboflavin, Trolox, and Singlet Oxygen Using Single Carbon Nanotube Fluorescence Spectroscopy

Ardemis Anoush Boghossian

Single-mol. fluorescent microscopy allows semiconducting single-walled carbon nanotubes (SWCNTs) to detect the adsorption and desorption of single adsorbate mols. as a stochastic modulation of emission intensity. In this study, we identify and assign the s ...

Extent-based incremental identification of reaction systems – Minimal number of measurements for full state reconstruction

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

The identification of kinetic models is an essential step for the monitoring, control and optimization of industrial processes. This is particularly true for the chemical and pharmaceutical industries, where the current trend of strong competition calls fo ...

Comparison of Three Methods of Biocompatible Multi-Walled Carbon Nanotubes Confinement for the Development of Implantable Amperometric Adenosine-5′-Triphosphate Biosensors

Giovanni De Micheli, Sandro Carrara, Andrea Cavallini

An amperometric biosensor for adenosine 5 -triphosphate (ATP) was developed applying a competitive assay of two glucose converting enzymes: glucose oxidase (GOD) and hexokinase (HEX). Competition between GOD and HEX for glucose in presence of ATP, lead to ...

First-Principles Study of Non-heme Fe(II) Halogenase SyrB2 Reactivity

Nicola Marzari

We present here a computational study of reactions at a model complex of the SyrB2 enzyme active site. SyrB2, which chlorinates L-threonine in the syringomycin biosynthetic pathway, belongs to a recently discovered class of alpha-ketoglutarate (alpha KG), ...

Mechanical effects of alkali silica reaction in concrete studied by SEM-image analysis

Mohsen Ben Haha

The occurrence of alkali-silica and alkali-silicate reactions causes damage in concrete. Even though the reaction has been known for some time, the progress of reaction in affected structures is difficult to predict. This research programme aims to study t ...

RNA-sequence or nucleoside/nucleotide analogues and method for producing the analogues

Sébastien Porcher

Nucleic acid sequence analogues, in particular tRNA analogues comprising in the place of a 3'-terminal adenosine a 3'-terminal 2'-deoxy-2'-thioadenosine are able to react site-specifically with weakly activated amino acid derivatives (e.g. phenylthioesters ...

2006

The first results of a study aiming at an efficient prepn. of a large variety of 2'-O-[(triisopropylsilyl)oxy]methyl(=tom)-protected ribonucleoside phosphoramidite building blocks contg. modified nucleobases are reported. All of the here presented nucleosi ...
