Analyte Detection with High Affinity Chemosensors (Emmy-Noether group)

Contents

 

Project Description

The creation of artificial receptors remains an open challenge in supramolecular chemistry. In particular, the detection of small biomolecules in aqueous or complex biological media by supramolecular chemosensors proved difficult. We have developed a remarkably facile and versatile biomimetic strategy for the design of high-affinity artificial receptors by exploiting a combination of specific analyte-host interactions and the powerful, non-classical hydrophobic effect as driving forces for binding.[1]  Current developments include the monitoring of dynamic processes, e.g. of enzymatic reactions,[2] and the extension of the sensors to applications in living cells.

Team Members

Open Positions

PhD position available. We are looking for a Chemist (m/f) who is interested in supramolecular chemistry and assay development to join our team as a PhD candidate. We offer an in interdisciplinary projects in the area of design and synthesis of novel sensors and their application to biomolecule and drug sensing and reaction monitoring of biological processes in real time. Close supervision by an experienced PostDoc and group leader will be provided. State-of-the-art equipment is available. The candidate should bring the desire to learn and try out new things; experience in organic synthesis and spectroscopy would be helpful. For applying to become a PhD candidate in our group, please send your CV and a motivation letter (English or German). If you are interested in a Master project, feel free to contact us.
