Discover fields of our research work

The Laboratory of Clinical Biophysics is devoted primarily to theoretical and experimental research of clinically relevant problems by including methods of physics. We stand for life-friendly methods and promote collaboration between different fields of knowledge.

The properties of cell and phospholipid membranes are studied with special emphasis on cellular vesicles and small (anisotropic) structures such as nanotubules and pores. Nanotubules and microexovesicles are considered as transport systems within the body and are important in basic physiological processes in health and disease.

A noninvasive method for determination of the contact hip stress in adult human hip and hip endoprothesis (HIPSTRESS) has been developed and validated in collaboration with orthopedic surgeons and traumatologists.

Other subjects of interest include theory of electric double layer, theory of elastomechanics, theory of self-assembly, theory of thin anisotropic structures (organic and inorganic nanotubes, ribbons, stripes and nonlamelar lipid structures) and experiments with giant phospholipid vesicles, human blood constituents and cell cultures.

Collaborative partners are Laboratory of Physics, Faculty of Electrical Engineering, , Department of Orthopaedic Surgery, University Medical Centre Ljubljana, and Laboratory for Extracellular Vesicles and Mass Spectrometry, National Research Council of Italy, Naples, Italy

The head of the Laboratory of Clinical Biophysics Veronika Kralj-Iglic is presently coordinating a project "Optimization of autologous platelet and extracellular vesicles rich plasma for treatment of postoperative wounds in otorhinolaryngology" financed by Slovenian Research Agency (ARRS) by the number J3-3066. The overall objective of the project is to improve the methodology of preparation of autologous blood-derived products. This is being achieved through the collaboration of an international multidisciplinary team addressing the following specific goals within the workpackages (WPs):

(i) To determine the effects of processing on plasma and on EV isolate composition  (WP1)

(ii) To set-up and apply analytical pipeline to a comprehensive characterization of key molecular players in plasma (WP2)

(iii) To implement and validate the preparation in a clinical study (WP3)

(iv) To propose individualized protocol and develop new device for next-generation plasma preparation (WP4)
