Title: Nanotechnology based antimicrobial and antiviral materials Abstract: Until the global COVID-19 pandemic, the antimicrobial resistance was one of the most problematic threats to the health of the world population. In our group, this problem was targeted by the usage of nanoparticles to control infections gained by exposure to MRSA and MSSA microbial strains.
Until the global COVID-19 pandemic, the antimicrobial resistance was one of the most problematic threats to the health of the world population. In our group, this problem was targeted by the usage of nanoparticles to control infections gained by exposure to MRSA and MSSA microbial strains. Currently, the biocontamination of medical devices and implants is a growing issue that causes problems since the transmission via contaminated surfaces has been recognized as an important route for spreading such microorganisms, as well as of SARS-CoV-2 viruses. Therefore significant efforts are currently being made to develop antibacterial hydrophobic surface coatings that can be used for different medical purposes, from catheters, textiles, bandages and others. Advances in nanotechnology and material sciences have made it possible to design smart surfaces for decreasing infections. This presentation will present the ongoing research on the development and optimization of active antimicrobial and antiviral coatings containing nanoparticles of metals and metals oxides, as well as their mixtures. The chemical characterization of several types of materials, in the nano layer and nanomaterial form, and assess the possibility of implementing these as antimicrobial/ antiviral coatings will be presented. Obtained data on the toxicity to particular microorganisms will be also discussed. Finally, the future perspectives with regards to emerging antimicrobial technologies in the fight against microorganisms and viruses, developing synthetic surfaces, which reduce the adhesion of microbes and provide biocidal and antiviral activity or combinatory effects, will be proposed.
Assoc. prof. Iva Rezić PhD PhD was a Vice-dean for scientific research until October 2020, at the University of Zagreb, where she leads a group of scientists in the field of material sciences, and teaches in chemistry corse. She has a double doctor of science degree – in the field of natural sciences (analytical chemistry) and technical sciences (textile engineering). Professional competences she applies in management of projects and teams, with current focus on development of antimicrobial coatings and antimicrobial biodegradable products. She published more than 60 scientific papers, 3 university textbooks and 5 chapters in scientific books.
