| Fertigkeiten |
Kenntnisse |
| (*)More specifically, upon completion of the course, students will be able to
• Explain fundamental biophysical concepts and methods in membrane biophysics (K1).
• Plan a sequence of experiments to characterize biological samples (K2/K3).
• Prepare biological samples (K3).
• Perform a sequence of experiments with basic biophysical laboratory equipment (K3).
• Analyze and evaluate the data by digital means, perform basic calculations, and summarize the obtained results in a report (K4/K5).
• Critically discuss the results, also in the context of the scientific literature (K5).
|
(*)Students will acquire theoretical and practical knowledge in the experimental characterization of biological systems with a focus on artificial membrane systems. Topics and methods include, but are not limited to:
• Surface potential measurements utilizing a fluorescent reporter
• Membrane fusion via turbidimetry, FRET, and fluorescent self-quenching
• Critical micellar concentration (CMC) utilizing contact angle measurements
• Membrane permeability estimation via the membrane potential
• Conductivity of peptidic channels via single-channel recordings
In addition, students will be familiarized with laboratory safety issues.

|
| Beurteilungskriterien |
(*)The final grade will be a combination of the student's preparation and execution of the experiment and the quality of the written protocols for each experiment.
|
| Lehrmethoden |
(*)Students are divided into groups of three and conduct four separate experiments.
