Membrane nanotubes drawn by optical tweezers transmit electrical signals between mammalian cells over long distances

Horst Vogel, Marinela Gjoni Boillat, Pedro Pascoal, Davor Kosanic

Biological cells continuously change shape allowing essential functions such as cell motility, vesicle-mediated release/uptake of soluble and membrane components or nanotube-mediated cell–cell communications. Here we use single cell micromanipulation to in ...

Optical trapping and micromanipulation of biological objects in microfluidic channels

Marinela Gjoni Boillat

The main aim of this project was to develop novel concepts for miniaturization of bioanalytical techniques for investigating biomolecular interactions. We used optical tweezers to selectively address individual biological objects in microfluidic channels. ...

Determining a receptor-ligand interaction useful in e.g. drug screening involves repetitive application of reversibly binding fluorescent ligands with fast association-dissociation kinetics

Rudolf Hovius, Horst Vogel, Marinela Gjoni Boillat, Jean-Manuel Segura, Christoph Schreiter

NOVELTY - Determining a receptor-ligand interaction involves repeatedly contacting a cell comprising a receptor, with a ligand, of the receptor in which the ligand has a fluorescence labeling group and binds reversibly to the receptor under conditions in w ...

Synthesis of nanoscopic optical fibers using lipid membranes as templates

Rudolf Hovius, Pierre Stadelmann, Horst Vogel, Dimitrios Stamou, Marinela Gjoni Boillat, Jean-Manuel Segura, Gopakumar Gopalakrishnan, Kurt Schenk, Cédric Gaillard

High-aspect-ratio, monocryst. Cd chloride nanowires doped with fluorescent CdS nanoparticles were synthesized using planar lipid membranes as templates. Cd2+ ions bound to the lipid bilayers (a) are released at low pH to the nanometer-sized, interlamellar ...

Reversible sequential-binding probe receptor-ligand interactions in single cells

Rudolf Hovius, Horst Vogel, Marinela Gjoni Boillat, Jean-Manuel Segura, Christoph Schreiter

With the reversible sequential (ReSeq) binding assay, we present a novel approach for the ultrasensitive profiling of receptor function in single living cells. This assay is based on the repetitive application of fluorescent ligands that have fast assocn.- ...
