Description

The Department of Physical Chemistry and Technology of Polymers of the Faculty of Chemistry at the Silesian University of Technology in Gliwice, Poland is seeking a candidate for a doctoral student position in photoactive layers formation & characterization in the framework of a SONATA BIS programme project “Light-Activated AntiMicrobial (LAAM) coatings: future application of modern energy transfer organic materials” funded by the National Science Centre of Poland.

Project outline

The presented project is addressed towards the formation and wide characterization of the new covalently attached layers containing organic photosensitizers that could be applied as Light-Activated AntiMicrobial (LAAM) coatings. New heavy-atom-free triplet organic photosensitizers containing various light-harvesting antennas and surface-anchoring groups will be firstly synthesized and then immobilized on a solid support in (electro)chemical grafting processes. The photophysical and photochemical properties of the photosensitizers will be characterized both in a solution or in a form of a film. Additionally, several spectroscopic and microscopic techniques, like UVVis, XPS, Raman, IR, AFM, SEM, contact angle measurements will be applied for the characterization of the deposited coatings. Finally, an attempt will be made to boost also the antifouling properties of the coatings by changing the hydrophobicity of the LAAMs by forming mixed monolayer. In the last step, the antimicrobial activity of the thin layers will be tested using most common bacterial strains, like Staphylococcus aureus or Escherichia coli. The crucial achievement of the project should be the formation of the stable antimicrobial coatings generating ROS with the high efficiency under the illumination of daylight.

Doctoral student’s responsibilities

The Doctoral student will join the research project entitled: “Light-Activated AntiMicrobial (LAAM) coatings: future application of modern energy transfer organic materials”, funded under the SONATA BIS 11 call.
