Resolving bacterial cell biology: from replisome dynamics to cell wall synthesis
Bacteria are ubiquitous single cellular organisms. Compared to eukaryotic cells, bacteria have two unique characteristics: the membrane-less nucleoid and the cell wall built of peptidoglycan (PG). In most bacteria, a single circular chromosome is compacted ...
EPFL2024Quantification of Native Lignin Structural Features with Gel-Phase 2D-HSQC0 Reveals Lignin Structural Changes During Extraction
Jeremy Luterbacher, Stefania Bertella
Our ability to study and valorize the lignin fraction of biomass is hampered by the fundamental and still unmet challenge of precisely quantifying native lignin's structural features. Here, we developed a rapid elevated-temperature H-1-C-13 Heteronuclear S ...
Wiley-V C H Verlag Gmbh2024Protocol for live imaging of intracellular nanoscale structures using atomic force microscopy with nanoneedle probes
Atomic force microscopy (AFM) is capable of nanoscale imaging but has so far only been used on cell surfaces when applied to a living cell. Here, we describe a step-by-step protocol for nanoendoscopy-AFM, which enables the imaging of nanoscale structures i ...
2023Biofilm morphogenesis on soft hydrogels
Bacteria often colonize their environment in the form of surface attached multicellular communities called biofilms. Biofilms grow from surface-attached cells that undergo division while self-embedding in a viscoelastic matrix. Biofilms grow at the surface ...
EPFL2023RUM: Reconfigurable Umbrella Mesh
Mark Pauly, Florin Isvoranu, Uday Kusupati, Seiichi Eduardo Suzuki Erazo
We propose Reconfigurable Umbrella Meshes (RUMs), a new class of preassembled deployable structures. A RUM has a compact rest state that can be easily altered to deploy into different bending-active 3D target shapes. RUMs consist of elastic beams and rigid ...
De Gruyter2023Influence of structural dynamics on cell uptake investigated with single-chain polymeric nanoparticles
Francesco Stellacci, Lixia Wei, Arthur Eliot Bouchez, Suiyang Liao
Most nanoparticles' parameters affect their interactions with cells. To date, all the parameters studied are basically static (e.g., size, shape, ligands, and charge). This is unfortunate, because proteins have struc-tural dynamics that most nanoparticles ...
CELL PRESS2023Investigating the bioaccumulation potential of anionic organic compounds using a permanent rainbow trout liver cell line
Kristin Schirmer, Juliane Hollender, Fabian Gerhard Peter Balk
Permanent rainbow trout (Oncorhynchus mykiss) cell lines represent potential in vitro alternatives to experiments with fish. We here developed a method to assess the bioaccumulation potential of anionic organic compounds in fish, using the rainbow trout li ...
PERGAMON-ELSEVIER SCIENCE LTD2023Carbon nanotube uptake in cyanobacteria for near-infrared imaging and enhanced bioelectricity generation in living photovoltaics
Ardemis Anoush Boghossian, Melania Reggente, Benjamin Paul Johanès Gabriel Lambert, Mohammed Mouhib, Charlotte Elisabeth Marie Roullier, Alice Judith Gillen, Alessandra Antonucci, Vitalijs Zubkovs, Nils Schürgers
Single-walled carbon nanotubes (SWCNTs) have unique optoelectronic properties that make them suitable for applications ranging from phototherapy to imaging and sensing, but their uptake has mainly been explored in eukaryotic cells. Here the authors explore ...
2022Fluorescent D-Amino Acids for Super-resolution Microscopy of the Bacterial Cell Wall
Suliana Manley, Luc Reymond, Chen Zhang, Ophélie Rutschmann, Willi Leopold Stepp, Faustine Ambroisine Charline Ryckebusch, Juliette Griffie, Jiangtao Qiao
Fluorescent D-amino acids (FDAAs) have previ-ously been developed to enable in situ highlighting of locations of bacterial cell wall growth. Most bacterial cells lie at the edge of the diffraction limit of visible light; thus, resolving the precise details ...
AMER CHEMICAL SOC2022Benthic Biofilms in Glacier-Fed Streams from Scandinavia to the Himalayas Host Distinct Bacterial Communities Compared with the Streamwater
Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Emmy Marie Oppliger, Virginia Tadei, Tyler Joe Kohler, Jade Brandani, Stylianos Fodelianakis, Paraskevi Pramateftaki, Vincent Henri De Staercke, Matteo Tolosano, Michail Styllas, Martina Andrea Schön
Microbial life in glacier-fed streams (GFSs) is dominated by benthic biofilms which fulfill critical ecosystem processes. However, it remains unclear how the bacterial communities of these biofilms assemble in stream ecosystems characterized by rapid turno ...
