Structural properties of magnetic nanoparticles determine their heating behavior – an estimation of the in vivo heating potential
Magnetically induced heating of magnetic nanoparticles (MNP) in an alternating magnetic field (AMF) is a promising minimal invasive tool for a localized tumor treatment by sensitizing or killing tumor...
PublikationenLocalisation microscopy with quantum dots using non-negative matrix factorisation
We propose non-negative matrix factorisation with iterative restarts (iNMF) to model a noisy dataset of highly overlapping fluorophores with intermittent intensities. We can recover high-resolution images...
PublikationenRaman Imaging with a Fiber-Coupled Multichannel Spectrograph
Until now, spatial-resolved Raman Spectroscopy required a time-consuming step by step scanning of the sample. Here we present a new technique, which allows the capture of an entire Raman image within one...
PublikationenReflectivity enhanced refractive index sensor based on a fiber-integrated Fabry-Perot microresonator
We discuss a fiber-integrated refractive index sensor with strongly improved detection performance. The resonator has been implemented by means of focused-ion beam milling of a step index fiber and shows...
PublikationenNanoparticle and nanosphere mask for etching of ITO nanostructures and their reflection properties
Au nanoparticles and polystyrene nanospheres were used as mask for plasma etching of indium tin oxide (ITO) layer. By reactive ion etching (RIE) processes, the morphology of polystyrene nanospheres can...
PublikationenPlasma treatment of ITO films for the formation of nanoparticles toward scalable production of novel nanostructure-based solar cells
Plasma treatment of indium tin oxide (ITO) has been studied to form metallic nanoparticles (NPs) for nanostructure-based solar cells. It is demonstrated that NPs can be formed at temperatures as low as...
PublikationenDiscrimination and Classification of Liver Cancer Cells and Proliferation States by Raman Spectroscopic Imaging
Discrimination of nodular lesions in cirrhotic liver is a challenge in the histopathologic diagnostics. For this reason, there is an urgent need for new detection methods to improve the accuracy of the...
PublikationenMulticrystalline silicon solar cells on glass based on a laser crystallization process using a new 980 nm diode laser developed by LIMO
This paper presents the preparation of multicrystalline silicon layers for thin film solar cells on glass by using a line focus diode laser emitting a wavelength of 980 nm. Previously, a diode laser emitting...
PublikationenDiffusion and Interface Effects during Preparation of All-Solid Microstructured Fibers
All-solid microstructured optical fibers (MOF) allow the realization of very flexible optical waveguide designs. They are prepared by stacking of doped silica rods or canes in complex arrangements. Typical...
PublikationenSilicon Thin Film Solar Cells Based on Diode Laser Crystallization and a-Si:H Hetero-Emitter
We present progress in multicrystalline silicon thin film solar cells on glass substrates with Absorbers based on a liquid phase diode laser crystallization process resulting in grains up to 1 mm in size....
