Self-defining tree-like classifiers for interpretation of Raman spectroscopic experiments
In this contribution, a technique is proposed to create a data-driven interpretation of a given chemometric analysis of a Raman dataset. In real-world applications, the chemometric analysis is fixed by...
PublicationsHyperspectral imaging of plasmon resonances in metallic nanoparticles
The spectroscopy of metal nanoparticles shows great potential for label-free sensing. In this article we present a hyper-spectral imaging system combined with a microfluidic system, which allows full spectroscopic...
PublicationsDemonstration of carbon catabolite repression in naphthalene degrading soil bacteria via Raman spectroscopy based stable isotope probing
Carbon catabolite repression (CCR) is a regulatory phenomenon occurring in both lower organisms like bacteria andhigher organisms like yeast which allows them to preferentially utilize a specific carbon...
PublicationsTunable nanoporous silicon oxide templates by swift heavy ion tracks technology
Nanoporous silicon oxide templates formed by swift heavy ion tracks technology have been investigated. The influence of the heavy ion characteristics, such as type of ion, energy, stopping power and irradiation...
PublicationsSpatial Resolution of Tip-Enhanced Raman Spectroscopy – DFT Assessment of the Chemical Effect
Experimental evidence of extremely high spatial resolution of tip-enhanced Raman scattering (TERS) has been recently demonstrated. Here, we present a full quantum chemical description (at the density functional...
PublicationsDetection of protein glycosylation using tip-enhanced raman scattering
The correct glycosylation of biopharmaceutical glycoproteins and their formulations is essential for them to have the desired therapeutic effect on the patient. It has recently been shown that Raman spectroscopy...
PublicationsSingle particle analysis of herpes simplex virus: Comparing the dimensions of one and the same virions via atomic force and scanning electron microscopy
Currently, two types of direct methods to characterize and identify single virions are available: electron microscopy (EM) and scanning probe techniques, especially atomic force microscopy (AFM). AFM in...
PublicationsSpectral characteristics of draw-tower step-chirped fiber Bragg gratings
This paper presents research results on the spectral properties of step-chirped fiber Bragg grating arrays written during the fiber drawing process into a birefringent optical fiber with an elliptical...
PublicationsDesign and First Applications of a Flexible Raman Micro-spectroscopic System for Biological Imaging
Typical commercial Raman micro-spectroscopic systems do not offer much flexibility to the end user, thus limiting potential research applications. We present a design of a simple, highly flexible and portable...
PublicationsRaman-based identification of circulating tumor cells for cancer diagnostics
Circulating tumor cells (CTCs) that can be extracted from body fluids offer new prospects in cancer diagnostics. An overview about our recent achievements is presented to use Raman-based methodologies...
