Your Job:

The current paradigm assumes that local anaesthetics (LA) act by occupying binding pockets in Na-ion channels of nerve cells, thereby blocking signal transduction. More recently, however, evidence has accumulated that a less specific mechanism of action also plays a role. Nuclear magnetic resonance (NMR) studies show, for example, that LAs preferentially accommodate into lipid membranes due to their amphiphilic nature, which alters the lateral pressure in the membranes. In the membranes of nerve cells, this could lead to ion channels being blocked without LA being incorporated into the channels.

It is therefore of great interest to quantify whether and to what extent LA change the lateral pressure in a membrane. As a first step in this direction, this project will use a Langmuir trough to measure how a series of LA affects the lateral pressure in a lipid monolayer. By systematically varying experimental parameters such as LA concentration, pH, etc. and correlating the results with existing data from NMR measurements, we will try to decipher non-specific mechanisms of LA action.

Your Profile:

  • Ongoing master’s study of physical chemistry or (soft condensed matter) physics
  • Basic knowledge of data and error analysis, as well as computer and programming skills
  • Interest in experimental and multidisciplinary work
  • High motivation as well as self-directed learning and working
  • Very proficient in written and spoken German and/or English
  • Basic knowledge of thermodynamics and statistical mechanics is desirable
