Prerequisites:
None

Academic preconditions:
General and broad knowledge corresponding to at least two years’ studies within basic sciences or medical sciences.

Course introduction
To provide the students with an understanding of the importance of quantitative, physical and physico-chemical concepts, experimental methods, and theoretical considerations in the description of complex biological systems, e.g. in relation to biomedical problems and applications.

Expected learning outcome
Upon completion of the course the student will be able to:

-characterize the most important physical techniques, concepts, and models used to describe biological systems and to account for their strong and weak points
- account for the importance of interfaces in relation to key biomedical systems, problems, and technological applications
- compose and present a talk on a topic within the broad area covered by the course (science students only)

Subject overview
The course combines fundamental concepts and phenomena in modern molecular biology and biomedicine with the use of these imaging and micromanipulation techniques to obtain cutting-edge knowledge of current problems, such as self-organization and assembly of biological structures; transport, diffusion and secretion of proteins; mechanical properties of membranes, nuclei, and whole cells; lateral organization of membranes in terms of lipid domains (rafts); traffic inside cells; interaction between lipids and proteins/receptors/enzymes; the role of unsaturated fats and cholesterol for membrane structure, membrane fluidity and permeability; the functioning of ion and water channels; the action of drugs and anaesthetics on membranes. Specific topics include: Membrane structure and channel function. Molecular mechanism of anaesthesia. Neurotransmitter action. Self-assembly. Energy and forces in biology. Membrane structure and dynamics. Lateral membrane structure: domains, rafts, and function. Lipid-protein interactions. Anti-microbial peptides. Cholesterol in membranes. Membrane fluidity, permeability, and mechanics. The liquid-ordered phase and its relation to rafts. Molecular evolution vs the evolution of species. Cholesterol transport in cells. Molecular biophysics of the living state of matter. Cellular function from the beginning to the end: apoptosis, ceramides, and programmed cell death. Biological imaging. Fluorescence microscopy techniques. Imaging by nano-particles in tissue. Visualization by atomic-force microscopy. Examples: Lung surfactant film; models of the human skin and the dermal barrier. Atomic force spectroscopy. Ligand-receptor interactions. Visit to the fluorescence-microscopy and atomic-force laboratories. Soft matter and forces between soft surfaces. Enzymatic action on soft surfaces and membranes. Liposomes for micro- and nano-scale encapsulation and drug delivery. LiPlasomes and their optimization for use in cancer therapy. Lipoprotein particles and atherothrombosis – molecular and cellular relationships. Red blood cells, cell nuclei and their shapes and shape transformations.
