Molecular intercalation in the van der Waals antiferromagnets FePS3 and NiPS3

Bruce Normand, Ying Chen, Sheng Xu, Shuo Li, Xiaoyu Xu, Zeyu Wang, Weiqiang Yu

We have performed electrochemical treatment of the van der Waals antiferromagnetic materials FePS3 and NiPS3 with the ionic liquid EMIM-BF4, achieving significant molecular intercalation. Mass analysis of the intercalated compounds, EMIMx-FePS3 and EMIMx-N ...

An Organometallic Compound which Exhibits a DNA Topology-Dependent One-Stranded Intercalation Mode

Paul Joseph Dyson, Ursula Röthlisberger, Giulia Palermo, Thibaud Edouard Alistair von Erlach, Benjamin Samuel Murray

Understanding how small molecules interact with DNA is essential since it underlies a multitude of pathological conditions and therapeutic interventions. Many different intercalator compounds have been studied because of their activity as mutagens or drugs ...

Influence of DNA Binding Dyes on Bare DNA Structure Studied with Atomic Force Microscopy

Giovanni Dietler, Aleksandre Japaridze, Aleksandr Benke, Sylvain Renevey

Fluorescent dyes are widely used for staining and visualization of DNA in optical microscopy based methods. Even though for some dyes the mechanism of binding is known, how this binding affects DNA remains poorly understood. Here we present a novel experim ...

Mechanistic Study on the Formation of Cl-/Br-/I-Trihalomethanes during Chlorination/Chloramination Combined with a Theoretical Cytotoxicity Evaluation

Urs von Gunten

Chlorination followed by chloramination can be used to mitigate the formation of potentially toxic iodinated disinfection byproducts (I-DBPs) while controlling the formation of regulated chloro-bromo-DBPs (Cl-/Br-DBPs). Water samples containing dissolved o ...

Mitonuclear protein imbalance as a conserved longevity mechanism

Johan Auwerx, Graham Knott, Laurent Mouchiroud, Richardus Houtkooper, Dongryeol Ryu, Elena Katsyuba, Norman Lionel Moullan

Longevity is regulated by a network of closely linked metabolic systems. We used a combination of mouse population genetics and RNA interference in Caenorhabditis elegans to identify mitochondrial ribosomal protein S5 (Mrps5) and other mitochondrial riboso ...

Time-Lapse AFM Imaging of DNA Conformational Changes Induced by Daunorubicin

Giovanni Dietler, Sandor Kasas, Giovanni Longo, Livan Bladimir Alonso Sarduy

Cancer is a major health issue that absorbs the attention of a large part of the biomedical research. Intercalating agents bind to DNA molecules and can inhibit their synthesis and transcription; thus, they are increasingly used as drugs to fight cancer. I ...

Study of Topoisomerase-DNA Interaction Using Atomic Force Microscopy

Livan Bladimir Alonso Sarduy

The aim of this thesis was to explore the topoisomerase-DNA interactions using atomic force microscopy (AFM) in a liquid environment. Firstly, we present a programmable microcontroller-driven injection system for the exchange of an imaging medium while usi ...

A Biochemical and Biophysical Investigation of 5-HT3 Receptor Stability

Menno Berend Tol

The 5-hydroxytryptamine 3 receptor (5-HT3R) is a member of the pentameric ligand-gated ion channel (pLGIC) family, that plays an important role in fast signal transduction and cell-cell communication in synapses: They convert a chemical signal from a neuro ...

Hydrogel-based three-dimensional matrix for neural cells

Patrick Aebischer, Nicolas Bouche

The ability to organize cells in three dimensions (3D) is an important component of tissue engineering. This study sought to develop an extracellular matrix (ECM) equivalent with a physicochemical structure capable of supporting neurite extension from prim ...
