Long-term STED imaging of membrane packing and dynamics by exchangeable polarity-sensitive dyes
Understanding the plasma membrane nanoscale organization and dynamics in living cells requires microscopy techniques with high spatial and temporal resolution that permit for long acquisition times and...
PublicationsA dinuclear osmium(II) complex near-infrared nanoscopy probe for nuclear DNA
With the aim of developing photostable nearinfrared cell imaging probes, a convenient route to the synthesis of heteroleptic OsII complexes containing the Os(TAP)2 fragment is reported. This method was...
PublicationsImproved temporal contrast of streak camera measurements with periodic shadowing
Periodic shadowing, a concept used in spectroscopy for stray light reduction, has been implemented to improve the temporal contrast of streak camera imaging. The capabilities of this technique are first...
PublicationsSuper-resolution imaging of highly curved membrane structures in giant vesicles encapsulating molecular condensates
Molecular crowding is an inherent feature of cell interiors. Synthetic cells as provided by giant unilamellar vesicles (GUVs) encapsulating macromolecules (polyethylene-glycol and dextran) represent an...
Publications | 29.10.2021Modulating the Excited-State Decay Pathways of Cu(I) 4H‑Imidazolate Complexes by Excitation Wavelength and Ligand Backbone
Cu(I) 4H-imidazolato complexes are excellent photosensitizers with broad and intense light absorption properties, based on an earth-abundant metal, and hold great promise as photosensitizers in artificial...
PublicationsAssessment of shifted excitation Raman difference spectroscopy in highly fluorescent biological samples
Shifted excitation Raman difference spectroscopy (SERDS) can be used as an instrumental baseline correction technique to retrieve Raman bands in highly fluorescent samples. Genipin (GE) crosslinked equine...
PublicationsA Molecular Photosensitizer in a Porous Block Copolymer Matrix-Implications for the Design of Photocatalytically Active Membranes
Recently, porous photocatalytically active block copolymer membranes were introduced, based on heterogenized molecular catalysts. Here, we report the integration of the photosensitizer, i. e., the light...
PublicationsRaman Stable Isotope Probing of Bacteria in Visible and Deep UV-Ranges
Raman stable isotope probing (Raman-SIP) is an excellent technique that can be used to access the overall metabolism of microorganisms. Recent studies have mainly used an excitation wavelength in the visible...
PublicationsBio-inspired self-assembly of large area 3D Ag@SiO2 plasmonic nanostructures with tunable broadband light harvesting
Tremendous efforts have been made to fabricate large-scale plasmonic nanostructures, which show wide applications in surface plasmon resonance (SPR) sensing, catalytic conversion, photothermal conversion,...
PublicationsThree-dimensional tracking of nanoparticles by dual-color position retrieval in a double-core microstructured optical fiber
Elastic light scattering-based three-dimensional (3D) tracking of objects at the nanoscale level is essential for unlocking the dynamics of individual species or interactions in fields such as biology...
