Microbe & material interactions research group
We have been studying the efficacy and mode of action of antimicrobial materials and coatings in cooperation with material scientists since 2015. The first project of the group that concerned antimicrobial materials ("In vitro toxicological tool-box for targeted design of antimicrobial nanomaterials”) aimed at finding of a set of effective microbicidal nanomaterials with minimal human hazard. The selected nanomaterials have a potential to be incorporated into a plastic matrix, or a polymer matrix, to be used as antimicrobial surface coatings. The results of this project were summarized in a popular science story.
Further development of antimicrobial coatings was carried out within two applied grants. In project “Novel antimicrobial surface coatings” we tested suitable matrices to which antimicrobial nanomaterials could be incorporated and another project “Development of antimicrobial surface coatings tested in real-life conditions into pilot production phase” focused on the development of matrices with an antimicrobial component to the production phase.
In addition to the development of antimicrobial materials and surfaces and their efficiacy testing we are also interested in studying the mechanisms of action of those materials as well as stress responses induced in bacterial cell.
Starting from 2020 the group has been involved in a project “Universal treatment method for antiviral protection of hard to clean surfaces” that focuses on antiviral materials and surfaces.
