Information about our lab's research projects

	Fast Super-resolution microscopy Project 1: Structured illumination microscopy >>> more information Project 2: Rotating coherent scattering (ROCS) microscopy >>> more information
	Nano-mechanics of helical bacteria in optical line traps Spiroplasms – propagation dynamics of the simplest form of life, trapped and scanned in a light tube. >>> more information
	Particle binding and uptake into cells >>> Graphical overview <<< Project 1: The nano-mechanics of phagocytosis >>> more information Project 2: *Cargo-transport by coupled molecular motors* >>> more information Project 3: *Membrane biophysics with giant unilamelar vesicles (GUV)* *>>> more information*
	Light-sheet microscopy (LSM) with self-reconstructing beams *Project 1: LSM using holographically shaped beams* >>> more information Project 2: LSM using Bessel beams with two photon excitation or STED >>> more information
	Momentum transport through bio-polymer networks We investigate viscoelastic properties of single and multiple microtubules coupled by thermally fluctuating trapped beads as nucleation sites. *>>> more information*
	Dynamics of MREB filaments inside Bacillus Subtilis With fast SR techniques we investigate cytoskeletal MreB filaments. These move through poorly understood mechanisms underneath the membrane of rod -shaped bacteria and help to organize the cell wall. *>>> more information*
	Surface Imaging with optically trapped probes Surface scanning with optically trapped probes in the presence of phase disturbing structures. *>>> more information*
	Plasmonic coupling of optically trapped particles We use video rate spectroscopy and MHz interferometric particle tracking to to understand the formation of metal nanoparticles (NP) to more complex structures inside an optical trap. *>>> more information*
	Simulations Wave optics. We developed theories and program code to describe light propagation in inhomogeneous media, scattering, optical forces and advanced 3D imaging. *>>> more information* Brownian Dynamics. We develop theories and program code to describe particular diffusion and binding in complex environments. *>>> more information*
	Dynamic Particle interactions Interferometric tracking of dynamic particle interactions with scanning line optical tweezers. *>>> more information*
