Division of Optometry and Spectroscopy

The Division of Optometry and Spectroscopy mainly conducts research using Raman and FTIR spectroscopy in the near and far infrared range in biological systems, including human tissues. One of the main research topics carried out by the Department is the spectroscopic verification of chemical changes occurring in the eye tissues (lens, capsule, fluid from the anterior chamber of the eye) during the occurrence of diseases of this organ and the coexistence of other diseases, such as diabetes. These studies are conducted in cooperation with ophthalmologists. In addition, the research performed in the Department includes the analysis of oncological samples and rare (genetic) diseases as well as spectroscopic evaluation of their treatment process, in particular:
  • Analyses of changes in breast tissues during the cancer disease.
  • Evaluation of the impact of tissue sample preparation methods for FTIR spectroscopy (paraffinized and non-waxed tissues).
  • Evaluation of the effectiveness of the applied anti-cancer therapy for breast tissue samples.
  • The use of FTIR in the diagnosis of Ewing sarcoma..
  • The use of FTIR in the diagnosis of neoplastic changes in lung tissue.
  • The use of the FEWS technique (Fiber Evanescent-Wave Spectroscopy) in optical studies of liquid biological samples.

Staff

Conducted research

Dr hab. Józef Cebulski, prof. UR - head of the division

Raman and IR (Fourier transform FTIR) spectroscopy investigations of semiconductor crystals, glasses and tissues. In crystals, research concerns the electron-phonon interaction. In glasses structural properties are studied. Tissues are investigated in order to establish the markers that can be useful in the treatment of selected cancerous tumors.

Dr inż. Grzegorz Gruzeł

 Preparation of noble metal nanoparticles and so-called nanoframes with different morphologies (shape, size, chemical composition, phase segregation) as potential nanocatalysts in fuel cells by chemical methods. Characterization of the obtained nanostructures by transmission and scanning electron microscopy, XRD, zeta potential measurements, and examination of their electrochemical properties in alcohol oxidation reactions.

Dr Yaroslav Shpotyuk

Investigation of amorphous materials based on chalcogenide glasses and ceramics used in infrared photonics, biomedical sensors and optoelectronic devices.
