Investigation of active mechanical properties in the cytoplasm of living cells
(2024-07-09)Over the past decades, the study of intracellular active mechanical properties has experienced a growth in interest. This is mainly caused by recognizing that vital cellular functions rely on the intricate interplay ... -
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 ... -
Modeling electrodynamics in the vicinity of metal nanostructures
(2019-03-08)In this work, we show how a profound theoretical understanding of a seemingly exotic phenomenon, namely the influence of metal structures on fluorescence lifetimes, has lead to the development of a microscopy technique ... -
Mechanosensing and Symmetry of Potassium Channels Studied by Molecular Dynamics Simulations
(2018-10-02)Potassium channels are relevant in a variety of physiological processes in all three kingdoms of life. In mammals these processes including nerve signaling, heartbeat regulation, and osmotic regulation of cells. Thus a ... -
Mechanical and biochemical stimulation of suspended cells in a microfluidic device probed with dual optical tweezers
(2018-01-30)Cells communicate with their environment through biochemical and mechanical interactions. They can respond to stimuli by undergoing shape- and, in some situations, volume changes. Key determinants of the mechanical response ... -
X-Ray Micro- and Nano-Diffraction Imaging on Human Mesenchymal Stem Cells and Differentiated Cells
(2017-06-13)Recent advances in hard x-ray optics, instrumentation and detection have made it possible to probe biological samples by combining diffraction with raster scanning, using step sizes on the order of cellular organelle ... -
Single-Molecule Metal-Induced Energy Transfer: From Basics to Applications
(2016-12-16)Single-molecule detection and spectroscopy have revolutionized the field of fluorescence microscopy. Due to their enormous potential in studying physics, chemistry and biology at molecular level, the number of single-molecule ... -
Atomic force microscopy study on the mechanics of influenza viruses and liposomes
(2012-11-28)Physics exists wherever there is matter: measures such as energy, mass, temperature, speed, dimension and stiffness are all examples of the physical properties. Such quantities are important characterizations for ...
