Raman spectroscopy towards clinical application: drug monitoring and pathogen identification
Raman spectroscopy is a label-free method that measures quickly and contactlessly, providing detailed information from the sample, and has proved to be an ideal tool for medical and life science research....
PublikationenData transmission with twisted light through a free-space to fiber optical communication link
Mode division multiplexing (MDM), where information is transmitted in the spatial modes of light, is mooted as a future technology with which to transmit large bits of information. However, one of the...
PublikationenFour-wave-mixing-based optical parametric oscillator delivering energetic, tunable, chirped femtosecond pulses for non-linear biomedical applications
A novel concept for an optical parametric oscillator based on four-wave mixing (FOPO) in an optical fiber is presented. This setup has the ability of generating highly chirped signal and idler pulses with...
PublikationenThe Green Gut: Chlorophyll Degradation in the Gut of Spodoptera littoralis
Chlorophylls, the most prominent natural pigments, are part of the daily diet of herbivorous insects. The spectrum of ingested and digested chlorophyll metabolites compares well to the pattern of early...
PublikationenRaman imaging to study structural and chemical features of the dentin enamel junction
The structure and chemical features of the human dentin enamel junction (DEJ) were characterized using Raman spectroscopic imaging. Slices were prepared from 10 German, and 10 Turkish teeth. Raman images...
PublikationenSize-dependent magnetic properties of iron oxide nanoparticles
Uniform iron oxide nanoparticles in the size range from 10 to 24 nm and polydisperse 14 nm iron oxide particles were prepared by thermal decomposition of Fe(III) carboxylates in the presence of oleic acid...
PublikationenThe effect of 3-amino benzoic acid linker and the reversal of donor-acceptor pairs on the electrochemical performance and stability of covalently bonded poly(pyrrole) nanotubes
The multiwall carbon nanotubes-polypyrrole (MWCNTs-PPy) composite is a well-known hybrid material suitable for energy storage applications such as capacitors. Since the electrochemical activity, and longterm...
PublikationenSurface Mobility and Ordered Rearrangement of Immobilized DNA Origami
The immobilization of DNA nanostructures on a surface is a key step for the integration of DNA-based material in nanotechnology for electronic or sensorial applications. Thereby the arrangement and distribution...
PublikationenStudying different illumination patterns for resolution improvement in fluorescence microscopy
Various types of non-uniform illumination can be used for resolution improvement in fluorescence microscopy. Here we study the differences between several types of incoherent illumination patterns, such...
PublikationenUltrafast transient absorption microscopy: Study of excited state dynamics in PtOEP crystals
We report a novel transient absorption microscope based on a tailor-made femtosecond fiber laser system operating at 250 kHz. The setup is applied to study PtOEP crystals embedded in a PBMA polymer matrix...
