In Vitro Fiber-Probe-Based Identification of Pathogens in Biofilms by Raman Spectroscopy
Biofilms are the preferred habitat of microorganisms on living and artificial surfaces. Biofilm-related infections, such as infections of medical implants, are difficult to treat, and due to a reduced...
Publications | 25.03.2022Advances in laboratory-scale ptychography using high harmonic sources [Invited]
Extreme ultraviolet microscopy and wavefront sensing are key elements for nextgeneration ultrafast applications, such as chemically-resolved imaging, focal spot diagnostics in pump-and-probe experiments,...
Publications | 21.03.2022Second Harmonic Generation Exploiting Ultra-Stable Resistive Switching Devices for Secure Hardware Systems
In the era of Big Data and Internet of Things (IoT), information security has emerged as an essential system and application metric. The information exchange among the ubiquitously connected smart electronic...
Publications | 21.03.2022Endoscopic Imaging Using a Multimode Optical Fibre Calibrated with Multiple Internal References
The interferometric acquisition of the transmission matrix (TM) of a multimode optical fibre (MMF), which is at the heart of multimode fibre-based endoscopic imaging methods, requires using a reference...
Publications | 21.03.2022Looking Inside Non-Destructively: Label-Free, Raman-Based Visualization of Intracellular Coxiella burnetii
The life cycle of intracellular pathogens is often complex and can include different morphoforms. Treatment of intracellular infections and unperturbed studying of the pathogen inside the host cell are...
Publications | 21.03.2022Wide-Bandgap Double Perovskites with Multiple Longitudinal-Optical Phonon Scattering
Alloyed lead-free double perovskites display intense photoluminescence, are environmentally friendly, and their devices show long-term operation. Thanks to these properties, which make them excellent warm...
Publications | 18.03.2022High-Resolution Kinoform X-Ray Optics Printed via 405 nm 3D Laser Lithography
Efficient focusing of X-rays is essential for high-resolution X-ray microscopy. Diffractive X-ray optics called kinoforms offer the highest focusing efficiencies in theory. However, they have long remained...
Publications | 18.03.2022Influence of non-Hermitian mode topology on refractive index sensing with plasmonic waveguides
We evaluate the sensing properties of plasmonic waveguide sensors by calculating their resonant transmission spectra in different regions of the non-Hermitian eigenmode space. We elucidate the pitfalls...
Publications | 18.03.2022Multispectral imaging flow cytometry for process monitoring in microalgae biotechnology
In the course of efficient development and optimization of biotechnological processes, the need for methods to track morphological and compositional changes of single cells is increasing. So far, the material...
Publications | 17.03.2022Super-resolution microscopy: a brief history and new avenues
Super-resolution microscopy (SRM) is a fastdeveloping field that encompasses fluorescence imaging techniques with the capability to resolve objects below the classical diffraction limit of optical resolution....
