Описание:The course is devoted to physics of interaction of laser radiation with biological objects and to analysis on these grounds of concrete examples of the applications of advanced laser technologies for diagnostics and modification of biomolecules, cells and tissues. The emphasis is made on the methods based on elastic, quasielastic and inelastic light scattering and, also, fluorescence of protein and DNA molecules, viruses, cells and tissues, and their physical models. State of the art is discussed in development of such novel perspective biophotonics techniques as coherence, diffuse and photoacoustic tomography, molecular imaging, laser manipulation of biological microstructures (laser tweezers), scanning laser microscopy, etc. Laser measurement techniques are described such as laser Doppler flowmetry and speckle velocimetry, diffractometry, polarimetry, etc. Also, the role of multiple scattering is discussed in the transfer of CW and pulsed radiation in biological objects, in particular, in imaging of such nonhomogeneities in tissues as blood vessels and tumors. Methods of numerical simulation are discussed in biophotonics research.
