Instrumental methods
This course is focused on instrumental methods of biophysics and molecular biology. Its main goal is to explain what problems can be solved using each of the methods and to teach how to select the simplest and the most effective approach to answer particular experimental question. Practical works will include planning of simple fluorescence or CD experiments and processing real experimental data from such experiments.
