Ferrofluids of magnetic multicore nanoparticles for biomedical applications
For a variety of magnetically based biomedical applications, it is advantageous to use sedimentation stable suspensions of relatively large (d >20 nm) magnetic core–shell nanoparticles. Water-based...
PublicationsMagnetic nanoparticles coated with carboxymethylated polysaccharide shells-Interaction with human cells
The interaction of magnetic core shell nanoparticles with living cells depends on the structure of the shell. In this paper we demonstrate a strong difference in the cell–nanoparticle interaction depending...
PublicationsEffect of supplementary manganese on the sporulation of Bacillus endospores analysed by Raman spectroscopy
It is a common practice in microbiology to induce and accelerate sporulation of spore-forming bacteria by adding small amounts of divalent manganese to the cultivation medium. By micro-Raman spectroscopy...
PublicationsBragg Grating Inscription in GeO2-Doped Microstructured Optical Fibers
PublicationsInscription of Fiber Bragg Grating Arrays in Pure Silica Suspended Core Fibers
Fiber Bragg grating (FBG) arrays in pure silica fourleaf-clover-shaped suspended core fibers were inscribed with two-beam interference and a deep UV femtosecond laser source. The target fibers are pure...
PublicationsTowards a specific characterisation of components on a cell surface – combined TERS-investigations of lipids and human cells
Supported lipid structures and human cells (human dermal derived keratinocyte, HaCaT) were investigated using tip-enhanced Raman spectroscopy (TERS) to use the high spatial resolution capabilities of TERS,...
PublicationsInvestigating Transverse Loading Characteristics of Microstructured Fiber Bragg Gratings With an Active Fiber Depolarizer
In this letter, the transverse loading characteristics of Bragg gratings in microstructured optical fibers were investigated by use of an active fiber depolarizer. Increasing transverse load shifts the...
PublicationsTip-enhanced Raman scattering studies of histidine on novel silver substrates
Tip-enhanced Raman scattering (TERS) experiments of histidine immobilized on an atomically flat silver surface are presented. The substrate consists of silver nanoplates with a diameter of a few micrometers...
PublicationsMagnetic iron oxide nanopowders produced by CO2 laser evaporation-‘In situ’ coating and particle embedding in a ceramic matrix
The CO2 laser evaporation technique is not only well suited for the production of magnetic iron oxide nanopowders, but also allows for their conditioning. Two optional methods, the ‘in situ’ coating...
