AB  - In this paper the authors present the results of surface characterisation of a lead telluride alloy conducted by atomic force microscopy and magnetic force microscopy. Relationship between surface morphology, in the range of several nanometres, and the magnetic properties allows precise determination of nanomagnetic particles size with their distribution within a scanned area. This method allows the characterisation of nanoparticles in dimensional and magnetic sense since the paramagnetic and diamagnetic range can be examined.

AB  - Hydrogen bond has dual property, classical (electrostatic interaction based on Coulomb's law) and quantum (wave function based on Schrodinger equation). Since Planck's constant is one of the main criteria for decision which process is quantum, or how much is close to be quantum, we use electrical and magnetic forces of valence electrons, as point of departure, to develop method for opto-magnetic fingerprint of matter. During the study of different type of matter we observed phenomena from spectral convolution data of digital images which characterize matter from both covalent and non-covalent bonding. Since water is matter that is most abundant with hydrogen bonds, we present results of 18.2 M Omega water investigation on different temperature and under influence of constant and variable magnetic fields by opto-magnetic method. Bearing in mind that Linus Pauling, in his book Nature of the Chemical Bond (Cornel University Press, 1939), for the first time presented the systematic concept of the hydrogen bond to the molecular world and its machinery, this paper is written in honor to him and 70th anniversary of one of the most important scientific paradigm.

AB  - Bioelectro-mechanical properties of skin can be very valid data for analyzing fractal
characteristics of skin structure. In this paper, bioelectrical impedance method and fractional calculus have been utilized for the characterization of the human skin. Our fractional model presents the generalized continuous Cole model which may predicts structural – functional parameters as a lot of Cole complex relaxation times. It is shown, using the proposed model and experimental results, that these parameters depend on the fractional indexes as a degree of the fractional derivatives in interval (0, 1] . These relaxation time constants correspond to structural – functional characteristics of the skin. The integral approximation of continuous fractional Cole model was done from ten points corresponding to orderly connected known reduced Cole elements. It was observed that five reduced Cole elements had significant values of corresponding relaxation times. At last, advantages of the proposed model are discussed.

AB  - In this paper we present applied physics research results of gas-permeable contact lenses (CL) that are manufactured from fluorosilicone acrylate based material (Boston T type). During contact lenses production the conformation states of polymers belonging to near surface layers of CL surface are changed. Since CL quality crucially depends on surface roughness and optical properties, the properties of surface molecules conformation state and their orientation come into perspective as important factors acting on the molecular level. Therefore, we investigated CL surface by phase contrast atomic force microscopy (PC-AFM), magnetic force microscopy (MFM), and optomagnetic fingerprint (OMF) technique and found out that surface quality and magnetic properties of contact lenses have influence on physical properties of light transmission and that these changes can be detected on the nanolevel of magnetism, as well as optomagnetism. These results carry important biophysically based implications for CL industry, biomedical application industry and applied optical science.

AB  - Motivated by characterization of paramagnetic materials (Al, Mn and Ti) and diamagnetic materials (Cu, C and Zn) by opto-magnetic method that is based on light-matter interaction using digital imaging, we present results of Epstein Barr virus (EBV) and cytomegalovirus (CMV) detection in blood plasma. To investigate light-blood plasma interaction we use wavelength difference of diffuse white light and reflected polarized light in red and blue channels of digital images (opto-magnetic method). Digital images of samples are analyzed by spectral convolution algorithm for light-matter interaction analysis. Since opto-magnetic method can detect very small difference between normal and pathological tissue states it is advantageous in comparison with classical methods. Especially it is important for early detection of suspicious tissue states and detection of viral infection presence in plasma. We compared our results with results of standard biomedical test for EBV and CVM, as a reference, and found out for group of 40 samples significant correlation of 93. 6%.
