Master thesis

DWI - Leibniz-Institut für Interaktive Materialien, Aachen

DWI – Leibniz Institute for Interactive Materials is a research institution financed by the Federal Government and the State of North Rhine-Westphalia. It is member of the Leibniz Association and is located at the Campus Melaten of the RWTH Aachen University. Here international young and experienced scientists belonging to different disciplines develop interactive materials according to the principles of nature.

DWI invites applications for a position as

Master Student (d/f/m)

A significant proportion of biomaterials is colonized by bacteria and becomes the focus of device-related infections. Urinary catheters are among the ones with highest incidence of bacterial infection accounting for as much as 30% of all nosocomial infections and 20% of bacteremia. 70 to 80% of these infections are attributable to the use of an indwelling urethral catheter.

Your Tasks:

The objective of this thesis is to develop coatings for urinary catheters that can minimize the adhesion of bacteria as well as to introduce strategies to inactivate bacteria.

  • To develop coatings based microgels which can be applied from water suspensions.
  • To focus in the synthesis of microgels containing different betaines and the formation of coatings.
  • To become acquainted with various methods of characterization of the microgel particles and films, e.g.: light scattering, ellipsometry, atomic force microscopy and thermogravimetric analysis.

Your Profile:

  • You should be highly motivated and be interested polymer and colloidal chemistry as well as biointerfaces.
  • Good communication skills and the ability to work in an interdisciplinary team are required

DWI offers:

  • exciting and challenging tasks as well as development opportunities in a modern scientific organization
  • An open and team-oriented working atmosphere in an international environment
  • The support of an experienced team.

DWI supports you to gain further qualifications. We offer our employees a broad spectrum of career opportunities in an attractive working climate. 

DWI supports equal opportunities of women and men. There is a possibility that the position can also be fulfilled in part-time, unless there are compelling professional reasons to do otherwise.

We at the DWI - Leibniz Institute value diversity and therefore welcome all applications - regardless of gender, disability, nationality or ethnic and social background.
