Group of nanostructures and technology:

Nanotechnology laboratory

The group is working on development, understanding and application of one of the most important surface investigation technique: Scanning Probe Microscopy (SPM) in UHV, and on application Molecular Beam Evaporation (MBE) for insulator/semoconductor and metal/insulator thin films.

Within the group's focus are:
Scanning Probe Microscopy, and especially Dynamic Force Microscopy (DFM) application to complex reconstructed semiconductor surfaces, and image interpretation. more...
Development of equipment and understanding of Kelvin Force Probe Microscopy, especially on ion-modified semicondutor surfaces.
Investigation of growth of ultra-thin films and nanostructures by MBE. more...

Physics of surfaces and nanostructures

The group is carrying out investigation into understanding of surface of complex reconstructed semiconductor surfaces and into process leading to surface nano-modification.

The main topics are:
Ion-induced modification of semiconductor surfaces leading to creation nanoscale wires.
Electron- and photon- induced desorption of alkali halides leading to topography dependent surface erosion. more...
Investigation of atomic stucture of III-group element rich reconstructions of AIIIBVcoumpounds. more...

Biophysics laboratory

The group is focused on the monitoring of the phenotypic changes of various cells stimulated with active agents, like drugs, nanoparticles or environmental factors. Our laboratory is fully equipped in order to maintain and develop cell cultures. The key experimental techniques are based on the Atomic Force Microscopy. Our group actively develops AFM-derived methods, like nanoindentation spectroscopy with an AFM tip or dynamic force spectroscopy, which enable to characterize not only the topography, but elasitic and adhesive properties of the cells as well. Additionally, fluorescent microscopy is used to track changes of cell's structural elements. Moreover, Raman spectroscopy coupled with AFM opens possibilities to characterize chemical composition with high resolution using SERS and TERS techniques. 

The areas of interest:

  • the influence of drugs on the phenotype of the cells more...
  • bio-molecular interactions studied with Dynamic Force Spectroscopy more...
  • cell apoptosis, in particular of the tumor cells more...
  • development of high resolution Raman spectroscopy techniques more...
