STED microscopy with two-photon photoactivation in the visible range & Application of generative adversarial networks for image reconstruction in STED microscopy
(2023-01-31)The resolution limit of classical optical far-field microscopes was broken with the invention of super-resolution microscopy. Today, a variety of these techniques achieving different degrees of resolution exist. Image formation ... -
Localizing and tracking of single molecules with a MINFLUX-microscope for various applications
(2022-01-25)Recently MINFLUX microscopy was first published, a technique that localizes single fluorescent molecules by probing with a structured illumination excitation beam featuring a central intensity minimum. Single nanometer ... -
Quantum Sensing with NV Centers in Diamond
(2019-10-22)This thesis is concerned with studies involving quantum sensing based on Nitrogen-Vacancy (NV) center in diamond. Essentially, it attempts to address two important problems. First, enhancing the sensitivity of a single ... -
Towards Solid-State Spin Based, High-Fidelity Quantum Computation
(2018-11-30)This thesis is divided into two parts. Both of them investigate current topics in quantum information processing. The first employs super-resolving stimulated emission depletion (STED) fluorescence microscopy for the ... -
Coordinate-targeted optical nanoscopy: molecular photobleaching and imaging of heterostructured nanowires
(2018-11-22)Super-resolution far-field fluorescence microscopy (optical nanoscopy) is a mature set of methods which enable visualization of the nanometer-scale distribution of objects such as organic molecules, photoswitchable proteins, ... -
Intelligent-Illumination STED
(2018-04-10)Recently established fluorescence superresolution microscopy techniques, such as stimulated emission depletion (STED), are capable of imaging fixed and living cells at the nanometer scale. In STED, ON- and OFF-switching ... -
Localizing and tracking of fluorescent molecules with minimal photon fluxes
(2018-01-19)In this thesis MINFLUX is presented, a novel optical scheme to determine the position of individual photon emitters in space. By probing the emitter with adapted illumination profiles featuring an intensity zero, the number ... -
Einzelmolekülstudien auf Nanoskalen: STED Fluoreszenzfluktuationsspektroskopie
(2009-06-17)Fluorescence Microscopy Methods are widely used in the Life Sciences to visualize and spectroscopically analyze biologically processes. Single molecule methods, such as FCS (Fluorescence ... -
High-Resolution Microscopy with Photoswitchable Organic Markers
(2009-03-23)The resolution of conventional microscopes is limited by Abbe"s diffraction barrier. The resolution barrier, however, can be fundamentally broken by sequentially switching marker substances ... -
3D STED Microscopy with Pulsed and Continuous Wave Lasers
(2008-04-16)STED microscopy improves the resolution of fluorescence microscope by effectively quenching the population of the excited state in the outer regions of the focus. The resolution capability in STED microscopy has already ... -
Ground State Depletion Fluorescence Microscopy
(2008-01-16)Microscopy is one of the most important analysis tools of modern science. One defining attribute of a microscope is its resolution as it specifies the minimum distance at which one can ...
