In view of future generations of biosensors, the immobilization of biomolecules onto selected materials with a well controlled topical addressability is of primary importance. Photoimmobilization is a technique allowing the immobilization of a biomolecule ...
We will present experimental and theoretical studies of optical fields with subwavelength structures, in particular phase singularities and coherent detection methods with nanometric resolution. An electromagnetic field is characterized by an amplitude, a ...
Visualization of ice particles in a rectangular cavity and ice slurry flows in a pipe are performed. The form and size of ice particles is investigated by optical microscopy, which permits a statistical evaluation of the geometrical shapes of the ice cryst ...

Scanning near-field optical microscopy (SNOM) makes it routinely possible to overcome the fundamental diffraction limit of standard (far-field) microscopy. Recently, aperture-based infrared SNOM performed in the spectroscopic mode,using the Vanderbilt Univ ...
Using a fully vectorial three-dimensional numerical approach (generalized field propagator, based on Green's tensor technique), we investigate the near-field images produced by subwavelength objects buried in a dielectric surface. We study the influence of ...
The phase equilibria of the ternary Al-AlCo-AlNi system were investigated around the decagonal phase. Isopleths with 70, 71.5 and 72.5 at.% Al and with 10 and 13 at.% Ni are elaborated with the aid of differential thermoanalysis, magnetothermal analysis, o ...
Scanning near-field optical microscopy (SNOM) is an optical microscopy whose resolution is not bound to the diffraction limit. It provides chemical information based upon spectral, polarization and/or fluorescence contrast images. Details as small as 20 nm ...
We present three-dimensional simulations of the image formation process in near-field optical microscopy, Our calculations take into account the different components of a realistic experiment: an extended metal coated tip, a subwavelength sample and its su ...
This paper. discusses recent theoretical efforts to develop a general and flexible method for the calculation of the field distributions around and inside complex optical systems involving both dielectric and metallic materials. Starting from the usual lig ...
A new class of molecules for the preparation of self-assembling biomaterials were synthesized. These molecules consist of a cholesteryl-moiety attached via an oligo(ethylene oxide) or oligo(L-lactic acid) segment to a biologically relevant headgroup. The o ...
