Shape-shifting of vesicles induced by artificial tubular networks

Projektbeschreibung

Dynamische Vesikel mit künstlichem Zytoskelett optimiert

Vesikel sind von einer Doppellipidschicht umgeben und dienen als künstliche Modelle von Zellmembranen. Ein wissenschaftliches Team aus dem EU-finanzierten Projekt SHINEShift will nun Vesikel in dynamische Strukturen umwandeln, die auf externe Reize reagieren und mechanischem Druck standhalten können. Mithilfe von synthetischer Chemie wird in den Vesikeln ein künstliches Zytoskelett aufgebaut, das aus peptidbasierten kleinen Kanälen besteht. Diese Kanäle reagieren auf Licht, indem sie Formen bilden und wachsen. Für solche technisch optimierten Vesikel ergeben sich noch viele weitere Anwendungsmöglichkeiten. Die entstandenen Methoden können außerdem auch in anderen Bereichen, wie der synthetischen Biologie oder Werkstoffwissenschaft, zum Einsatz kommen.

Ziel

The most commonly used artificial cell membrane models are vesicles. However, these static structures, consisting of a lipid bilayer surrounding a fluid, are poor in resisting mechanical stress. Enhancing their mechanical properties with a dynamic artificial cytoskeleton will both allow stabilizing their shape and transforming these passive objects into dynamic stimuli-responsive systems. In this MSCA project photo-responsive synthetic supramolecular tubules will be used as an artificial cytoskeleton inside vesicles. My aim is to develop stiff and at the same time responsive tubules based on cyclic peptide design that can grow and generate pushing forces during the fueling step, and disassemble when the fuel stops, both in a fully reversible manner. This cutting edge interdisciplinary project brings together several disciplines in chemistry, i.e. organic synthesis and supramolecular chemistry with colloidal chemistry (and/or microfluidics), and its scientific impact will spread through various fields – from supramolecular chemistry to material science (leap from static vesicles to dynamic ones), and synthetic biology (relevance for future applications in the field of artificial cells). My expertise as experienced researcher in the field of organic synthesis will be applied to the field of dynamic supramolecular systems based on photo-switchable compounds in which the host (Dr. Kudernac) has made notable recent progress. During this training-through-research project I will be able to learn the preparation processes for the vesicles and microscopy techniques that are fundamental for investigating (dynamic) supramolecular assemblies and which will further expand my horizontal skills. In addition, training activities during this fellowship will strongly enhance my leadership and transferable skills. Hence, the Fellowship will allow me to become a distinctive researcher in a highly competitive scientific environment.
