Raman and Infrared Spectroscopy Distinguishing Replicative Senescent from Proliferating Primary Human Fibroblast Cells by Detecting Spectral Differences Mainly Due to Biomolecular Alterations
Cellular senescence is a terminal cell cycle arrested state, assumed to be involved in tumor suppression. We studied four human fibroblast cell strains (BJ, MRC-5, IMR-90, and WI-38) from proliferation...
PublicationsApplication and fabrication aspects of sub-micrometer-sized Josephson junctions
We present the description of two methods for the fabrication of sub-micron sized Josephson junctions, namely the shadow-evaporation technique and the cross-type technology. Their importance for the field...
PublicationsSelf-organized growth of germanium nanocolumns
The crystalline germanium nanostructures were obtained on silicon surface by chemical vapor deposition technique using a germanium (IV) iso-propoxide ([Ge(OiPr)4]) metalorganic precursor as a germanium...
PublicationsFiber Fabry-Perot Interferometer for Curvature Sensing
A curvature sensor based on a Fabry-Perot (FP) interferometer is proposed. A capillary silica tube is fusion spliced between two single mode fibers, producing an FP cavity. Two FP sensors with different...
PublicationsBacterial community and PHB-accumulating bacteria associated with the wall and specialized niches of the hindgut of the forest cockchafer (Melolontha hippocastani)
A characterization of the bacterial community of the hindgut wall of two larval and the adult stages of the forest cockchafer (Melolontha hippocastani) was carried out using amplicon sequencing of the...
PublicationsPhotophysics of BODIPY dyes as readily designable photosensitisers in light-driven proton reduction
A series of boron dipyrromethene (BODIPY) dyes was tested as photosensitiser for light-driven hydrogen production in combination with the complex [Pd(PPh3)Cl2]2 as the source for catalytically active...
PublicationsPolymeric Halogen-Bond-Based Donor Systems Showing Self-Healing Behavior in Thin Films
The synthesis and comprehensive characterization of a systematic series of cleft-type anion receptors imbedded into a polymeric architecture is presented. For the first time, isothermal calorimetric titrations...
PublicationsStabilizing silica nanoparticles in hydrogels: impact on storage and polydispersity
For a successful nanomedicine, it is important that the unique, size-dependent physicochemical proprieties of the nanomaterial remain predictably constant during both the storage and the manipulation with...
PublicationsPolymeric Halogen-Bond-Based Donor Systems Showing Self-Healing Behavior in Thin Films
Dieser Beitrag beschreibt die Synthese einer systematischen Reihe polymerbasierter Anionenrezeptoren und deren anschließende umfassende Charakterisierung sowohl in Lösung als auch im Polymerfilm. Erstmals...
Publications(Sub)picosecond processes in DNA and RNA constituents: a Raman spectroscopic assessment
In this work, Raman total half bandwidths and the corresponding global relaxation times of seven nucleic acid constituents (adenosine, guanosine hydrate, cytidine, thymidine, uridine, adenosine 50-monophosphate...
