Learning outcomes of the learning unit
To visualise (macro)molecules and macromolecular structures and their interactions over time and space is essential to the understanding of the physiology of biological systems: from the basic organisation of a cell to the complex development of organisms. Molecular imagery today presents many possibilities - reaching the level of the nanometre and the millisecond - and it is used in the study of the dynamics of certain processes of great interest in living and functioning cells in various physiological situations, and under stress. Considerable advances in the area of cellular biology are continually being helped by technological advances. These include confocality, multiphoton, high resolution and high sensitivity detectors, cryomicroscopy, electron microscope tomography, deconvolution, etc. The object of the course is to acquaint students with these imaging tools briefly and to continue by examining applications of imaging techniques in the study of cells, and in the area of developmental biology.
