Molecular Plasmonics – light meets molecules at the nanoscale
Certain metal nanoparticles exhibit the effect of localized surface plasmon resonance when interacting with light, based on collective oscillations of their conduction electrons. The interaction of this...
PublicationsNanoscale structural analysis using tip-enhanced Raman spectroscopy
Tip-enhanced Raman scattering (TERS) enables the label free investigation of biochemical interfaces with nanometer lateral resolution by combining the benefits of the intrinsic molecular specificity of...
PublicationsVisualization and characterisation of defined hair follicle compartments by Fourier transform infrared (FTIR) imaging without labelling
Background: To visualise and characterise skin architecture, the tissue usually has to be destroyed and labelled. Objectives: The use of Fourier transform infrared (FTIR) spectroscopy as a label-free,...
PublicationsTip-Enhanced Raman Scattering (TERS) from Hemozoin Crystals within a Sectioned Erythrocyte
Tip-enhanced Raman scattering (TERS) is a powerful technique to obtain molecular information on a nanometer scale, however, the technique has been limited to cell surfaces, viruses, and isolated molecules....
PublicationsTuning of photocatalytic hydrogen production and photoinduced intramolecular electron transfer rates by regioselective bridging ligand substitution
Artificial photosynthesis based on supramolecular photocatalysts offers the unique possibility to study the molecular processes underlying catalytic conversion of photons into chemical fuels in great...
PublicationsORMOCER coated Fiber-Optic Bragg Grating Sensors at Cryogenic Temperatures
ORMOCER coated Fiber-Bragg-Gratings (FBG) were investigated at cryogenic temperatures. Below T = 40 K the Bragg wavelength of uncoated FBG is nearly independent on temperature. ORMOCER coated FBG are temperature...
PublicationsExcited-state annihilation in a homodinuclear ruthenium complex
Ultrafast excited-state annihilation in a homodinuclear ruthenium complex is observed. This coordination compound constitutes a model system for approaches towards artificial photosynthetic systems. The...
PublicationsSimultaneous topographic and amperometric membrane mapping using an AFM probe integrated biosensor
The investigation of the plasma membrane with intercorrelated multiparameter techniques is a prerequisite for understanding its function. Presented here, is a simultaneous electrochemical and topographic...
PublicationsAu/Ag/Au double shell nanoparticles with narrow size distribution obtained by continuous micro segmented flow synthesis
In this paper we present a two-step micro continuous flow-through method for synthesizing colloidal dispersions of noble metal core/shell and multishell nanoparticles in aqueous solutions in the presence...
PublicationsPlasmonic Nanofabrication by Long-Range Excitation Transfer via DNA Nanowire
Driven by the demand for ongoing integration and increased complexity of today’s microelectronic circuits, smaller and smaller structures need to be fabricated with a high throughput. In contrast to...
