Adaptive Scanning for STED Microscopy
(2020-02-06)Optical nanoscopy allows for highly specific imaging of biological tissue, cellular components and even single molecules and has therefore become an integral part of modern biomedical research. In STED microscopy, being ... -
Advanced multiplexing techniques in single molecule localisation microscopy
(2022-05-13)DNA point accumulation for imaging in nanoscale topography (DNA-PAINT) is a powerful super-resolution technique highly suitable for multi-target (multiplexing) bio-imaging applications. However, multiplexed imaging of cells ... -
Fast, Three-Dimensional Fluorescence Imaging of Living Cells
(2022-01-21)This thesis focuses on multi-plane fluorescence microscopy for fast live-cell imaging. To improve the performance of multi-plane microscopy, I developed new image analysis methods. I used these methods to measure and analyze ... -
High-Resolution Reflection Microscopy via Absorbance Modulation
(2023-01-11)The properties of composite materials are primarily governed by their microstructural features, which can vary in size from a few nanometres to several micrometres. Optical microscopy is one of the primary tools for ... -
Hochauflösende Bildgebung und NEXAFS-Spektroskopie mit weicher Röntgenstrahlung aus laserinduzierten Plasmen
(2019-01-24)Soft x-ray microscopy and absorption spectroscopy are extremely useful tools for high-resolution imaging and chemical analysis of samples in various scientific fields. However, due to the required high photon flux of ... -
Investigation of laser-induced structures on metal surfaces produced via two-beam and laser-plasmon interference
(2023-03-15)Periodic surface structures can change the properties of material surfaces. The obtained various functionalities strongly depend on the type of the specific structures. This work deals with the generation of periodic ... -
isoSTED microscopy for live cell imaging
(2019-05-08)Far-field fluorescence microscopy is a versatile tool for the non-invasive investigation of intracellular structures and thus for live cell imaging. This is a major advantage over other microscopy methods such as electron ... -
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 ... -
Low-dose, high-throughput scanning small-angle X-ray scattering of adherent mouse embryonic fibroblasts
(2022-02-24)Biological cells are highly variable: differences in e. g. gene expression emerge even among monoclonal cells in the same culture dish. The characterization of a highly variable statistical population calls for high-throughput ... -
New Concepts for STED Microscopy
(2022-01-04)Fluorescence nanoscopy allows to non-invasively resolve three-dimensional cellular structures beyond the diffraction limit. One of these high resolution imaging techniques is stimulated emission depletion (STED) microscopy. ... -
Statistical analysis methods for time varying nanoscale imaging problems
(2019-03-28)Microscopy is a valuable imaging method in life sciences. It was thought for a long time that its resolution was fundamentally limited by diffraction, described by Abbe's resolution limit. But this limit only takes into ... -
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 ... -
Stereo 3D-SMS microscopy of large sample volume
(2018-12-20)The functionality of the human body and with it many of its diseases are based on single cells or even on single cellular components. It is therefore essential to gain insight into the intra- and intercellular processes ... -
UV laser modification of transparent materials for photonic applications
(2023-04-28)Photonic applications have experienced strong growth in recent years. Due to increasing digitalization and automation in all areas of life, further growth of photonics is expected in the future. The broad range of photonic ...
