Polydopamine coated CdSe@CdS dot-in-rod heterostructures with Rhodium-based catalysts for stable photocatalytic NAD+ reduction
We report on a photocatalytic system consisting of CdSe@CdS nanorods, coated with a polydopamine (PDA) shell functionalized with molecular rhodium catalysts. The PDA shell was implemented to enhance photostability...
PublicationsBiochemical analysis of leukocytes after in-vitro and in-vivo ac-2 tivation with bacterial and fungal pathogens using Raman 3 spectroscopy
Biochemical information from activated leukocytes provide valuable diagnostic infor-27 mation. In this study, Raman spectroscopy was applied as a label-free analytical technique to char-28 acterize the...
PublicationsSupramolecular Reorientation During Deposition Onto Metal Surfaces of Quasi-Two-Dimensional Langmuir Monolayers Composed of Bifunctional Amphiphilic, Twisted Perylenes
Supramolecular dye structures, which are often ruled by ð−ð interactions between planar chromophores, crucially determine the optoelectronic properties of layers and interfaces. Here, we present the...
PublicationsDissecting molecular membrane organization – a super-resolution fluorescence spectroscopy story
Molecular interactions are key in cellular signaling. They are usually ruled by the organization and mobility of the involved molecules. We present different fluorescence spectroscopic tools that are able...
PublicationsDirect supercritical angle localization microscopy for nanometer 3D superresolution
3D single molecule localization microscopy (SMLM) has emerged as a powerful method for structural cell biology, as it allows probing precise positions of proteins in cellular structures at a resolution...
PublicationsQuantification of membrane fluidity in live epithelial cells treated by Candidalysin, a fungal peptide toxin secreted by C.albicans during invasion
To become pathogenic and translocate across the intestinal epithelium C.abicans fungus needs to change its morphology from yeast to invasive filamentous. Fungal cytolytic peptide toxin, Candidalysin secreted...
PublicationsUltrafast particle tracking of single lipid molecules in membranes through ISCAT and MINFLUX microscopy
The diffusion dynamics of lipids on cellular membranes have always proven particularly challenging to study in optical microscopy, given the highly heterogeneous nature of their environment. Given the...
PublicationsExchangeable polarity-sensitive dyes for real-time quantification of membrane biophysical properties using STED super-resolution microscopy
The understanding of the plasma membrane nano-scale organisation in living cells requires microscopy techniques with high temporal and spatial resolution that allow for the quantification of membrane biophysical...
PublicationsPolarization-resolved second-harmonic generation imaging through a multimode fiber
Multimode fiber-based endoscopes have recently emerged as a tool for minimally invasive endoscopy in tissue, at depths well beyond the reach of multiphoton imaging. Here, we demonstrate label-free second-harmonic...
PublicationsThree component SQUID based system for Airborne Natural Field Electromagnetics
Natural source electromagnetic surveys are today routinely performed from airborne platforms but limitations in measured components or bandwidth set margins to exploration depth and resolution. Utilizing...
