This work contains an analysis of the impact of modifying a bioresorbable polymer-polycaprolactone (PCL)-with various additives on its antibacterial properties. To this end, samples of PCL filament containing various content levels of graphene (GNP), 0.5%, 5%, 10%, were obtained using injection molding. Polymer samples without additives were used for comparison. The next step was to assess the antimicrobial impact of the preparations under study against the following microorganisms: ATCC 25293, ATCC 25922, ATCC 10231. Effective bactericidal activity of PCL with small amount of GNP, especially against and was confirmed. A decrease in this property or even multiplication of microorganisms was observed in direct proportion to the graphene content in the samples.
