The student should be able to:
- analyse binding phenomena and generate binding partition functions for biological systems and generate models for given equations;
- analyse the kinetics of binding phenomena and extract information from kinetic curves; design kinetic experiments to extract rate constants;
- analyse self-assembly of proteins, construct models and design experiments to extract kinetic and equilibrium information;
- explain diffusion and diffusional encounter between molecules and receptors;
- produce and interpret  graphical representations of the phenomena.

Knowledge of elementary mathematics: algebra, differentiation, integration. Knowledge of the concept of chemical equilibrium and the thermodynamic properties used to characterise equilibria (enthalpy, entropy, Gibbs free energy). General knowledge on the structure of biomolecules.
(Necessary basis to disciplines as offered in the introductory courses Structure, Synthesis and Cellular Function of Macromolecules; Atoomtheorie, chemische periodiciteit en chemische binding)

- Interactions between molecules: construction of binding functions and binding partition functions. Principle of linked functions. Cooperativity among sites and allostery. Binding to linear lattices (e.g. nucleic acids), overlapping binding sites (e.g. protein-nucleic acid interactions). A couple of experimental binding techniques: titrations, equilibrium and flow  dialysis.

- Kinetic studies of the interaction between molecules: association-, dissociation-, displacement and  competition kinetics. Diffusion to molecules and cell surfaces. Experimental techniques.

- Biopolymers as poly-electrolytes: counterion condensation with nucleic acids.

- Self-assembly of linear polymers: actin filaments, microtubules. Theory of Oosawa, dynamic instability. Open structures with length regulation: myosin assembly.

- Biological systems as dissipative structures: kinetic approach, oscillating systems.
