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, ... -
Fluorescence nanoscopy in three dimensions
(2010-03-11)Live-cell microscopy faces two challenges when neither the spatial nor the temporal information about the specimen should be lost. First, the microscope must be able to resolve the smallest ... -
Fast STED Microscopy
(2010-02-12)The spatial resolution of optical far-field microscopes was hampered by diffraction until STED microscopy broke the diffraction limit. This thesis for the first time combines the high spatial ... -
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 ... -
High-Resolution Fluorescence Microscopy with Photoswitchable Fluorescent Proteins
(2009-02-12)The diffraction limit in far-field fluorescence microscopy can be overcome by photoswitching the marker molecules between a fluorescent and a non-fluorescent state. Photoswitching enables ... -
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 ...
