Detection 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...
PublikationenSingle 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...
PublikationenSpectral 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...
PublikationenDesign 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...
PublikationenRaman-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...
PublikationenSignal amplification in a qubit-resonator system
We study the dynamics of a qubit-resonator system, when the resonator is driven by two signals. The interac-tion of the qubit with the high-amplitude driving we consider in terms of the qubit dressed states....
PublikationenTemperature sensing up to 1300°C using suspended-core microstructured optical fibers
We demonstrate a new approach to high temperature sensing using femtosecond laser ablation gratings within silica suspended-core microstructured optical fibers. The simple geometry of the suspended-core...
PublikationenTaming the Light in Microstructured Optical Fibers for Sensing
In this review, we examine recent developments in the field of chemical and biological sensing utilizing suspended-core, exposed-core, and hollow-core microstructured optical fibers. Depending on the intended...
PublikationenInterferometric-type optical biosensor based on exposed core microstructured optical fiber
This work presents a novel biosensor using the multimode interference effect in an exposed core microstructured optical fiber (ECF). In this work biotin molecules are immobilized onto the ECF core surface...
PublikationenSchwertmannite formation at cell junctions by a new filament-forming Fe(II)-oxidizing isolate affiliated with the novel genus Acidithrix
A new acidophilic iron-oxidizing strain (C25) belonging to the novel genus Acidithrix was isolated from pelagic iron-rich aggregates (‘iron snow’) collected below the redoxcline of an acidic lignite...
