Official IOE MUT Nanotechnology Group




The research activities of the IOE MUT Nanotechnology Group related to fabrication of various nanostructures are focused on the chemical fabrication of nanostructures and their composites as well as plasma deposition of nanostructured thin films.

The chemical methods are used in our laboratory to synthesize various nano- and submicro-particles with main focus on plasmonic nanoparticles (AuNPs, AgNPs) as well as SiO2 and TiO2 particles. In addition, we synthesize core-shell structures in various configurations based on Au, Ag, SiO2 and TiO2.

The surface modifications of fabricated nanostructures carried out in our laboratory allow i.e. to transfer synthesized nanoparticles to organic solvents and finally to form their composites with various materials, such as liquid crystals. The surface modification of various substrates is used for assembly of the nanoparticles on their surfaces. Such formed nanoparticles arrays can be further utilized to in example thin semicontinuous metal films. 

The plasma deposition of nanostructured thin layers is carried out using Pulsed Laser Deposition (PLD) system equipped with KrF excimer laser. The PLD method allows for deposition of very thin layers of complex materials on various kinds of substrates, including bio-compatible layers on implants or on artificial heart. Stoichiometric composition of the layer is comparable with stoichiometric composition of material being deposited what allows for deposition of layers having properties of initial material and thus obtaining, e.g., thin crystalline layers.


The spectroscopic techniques, such as UV-Vis-NIR, Fluorescence and Raman spectroscopies, provide important information about investigated materials. Our UV-Vis spectrometer equipped with integrating sphere allow us to measure optical properties of solid (powders, films) and liquid (solution, suspensions) samples. These measurements are especially useful for determination of plasmon resonance of plasmonic nanostructures or band gap of materials based on the TiO2.

Raman spectroscopy in recent years has become very important tool for characterization of various materials. In our laboratory we use this technique i.e. to investigate crystal phase composition of fabricated materials based on titania. In addition, in collaboration with other groups we investigate carbon materials such as graphene, carbon nanotubes or carbon gels. Our Raman system allows also for Raman imaging, which become more and more often use tool in our studies.

The AFM microscopy is a technique that allows imaging surface of any solid state material regardless of whether it is conductive or not. AFM topographic imaging provides information on the size of grains, their shape, orientation and distribution, surface roughness, structure height and other. In addition, advanced AFM techniques also allow high resolution imaging of various physical properties of micro-scale objects: local hardness, friction coefficient, electrical conductivity, surface potential and many others. Our AFM microscope is also integrated with a Raman spectroscopy. Integration of Raman spectroscopy with AFM microscopy opens a wide range of new capabilities in imaging and characterizing many types of samples. Raman maps with corresponding AFM images provide complimentary information to the AFM topography. 

The X-ray Photoelectron Spectroscopy is a very powerful tool used to study the surface properties of materials; in particular to study the chemical composition and determine the type of chemical bonds between the elements. In this method, the sample is illuminated by a beam of X-rays, and the recorded signal constitute the photoelectrons coming from the electron shells. Due to the small depth (up to 10 nm), from which the photoelectrons are recorded, this method is particularly useful to study the nanolayers and the surface-modified materials. In our group XPS spectroscopy is used mainly for study the polymers, metal oxides and carbon materials.

In the Particle Characterisation Laboratory we gathered particles analysers based on the DLS, SLS, NTA, TRPS and DCS methods as well as pycnometer for the density measurements. These instruments allow us to characterise following paramaters of the various type of particles: 

  • Size (from 0.3 nm to 80 µm)
  • Size distribution
  • Concentration
  • Zeta Potential
  • Surface Charge
  • Molecular Weigth
  • Density

The nanostructures fabricated by chemical methods, plasmonic nanoparticles, core-shells and thin films, were so far used for Surfaced Enhanced Raman Spectroscopy of chemical compounds and biological materials. Our portable Raman spectrometers should allow us to tests our nanostructures and methodologies outside the laboratory. Some of our structures were tested for use in Surface Enhanced Fluorescence (in collaboration with Prof. Maćkowski Group).

More recently we started exploring also new directions. Our studies on the TiO2 based nanostructures have led us to synthesis of materials suitable for photocatalysis and photovoltaics. In addition, we started work on the fabrication of the composites based on the plasmonic nanoparticles and liquid crystals for use in fibre optics (in collaboration with Prof. Woliński Group).

The thin layers of various materials deposited using PLD method were used mainly for biomedical and energy applications. The bio-compatible layers of hydroxyapatites were deposited in studies on implants and artificial heart.  The studies related to energy field involved fabrication of materials for fuel cells and hydrogen storage.
