Towards 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,...

Investigating 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...

Tip-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...

Magnetic 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...

SERS as tool for the analysis of DNA-chips in a microfluidic platform

Separation of CARS image contributions with a Gaussian mixture model

Coherent anti-Stokes Raman scattering (CARS) gained a lot of importance in chemical imaging. This is due to the fast image acquisition time, the high spatial resolution, the non-invasiveness, and the molecular...

Substitution-controlled ultrafast excited-state processes in Ru-dppz-derivatives

Ru–dppz (dppz = dipyrido[3,2-a:2′,3,3′-c]phenazine) complexes play an important role as environmentally sensitive luminescence sensors and building blocks for larger supramolecular compounds. Their...

Passive Submillimeter-wave Stand-off Video Camera for Security Applications

Axial p-n Junctions Realized in Silicon Nanowires by Ion Implantation

The electrical properties of vertically aligned silicon nanowires doped by ion implantation are studied in this paper by a combination of electron beam-induced current imaging and two terminal current-voltage...

Tip-Enhanced Raman Spectroscopy

This special issue of the Journal of Raman Spectroscopy deals with the advances of Tip-Enhanced Raman Spectroscopy (TERS) since its experimental verification about 10 years ago. The contributed papers...
