The aim of this study was to test the possibilities of using APCVD and CCVD to create effective antibacterial coatings and to determine their antibacterial activity. SiO x ‐layers were created by use of a hexamethyldisiloxane (HMDSO) precursor in combination with silver nitrate solution and silver nanoparticles as additives. A strong antibacterial effect of the APCVD and CCVD coated samples on an Escherichia coli ( E. coli ) strain could be shown. Layers obtained by CCVD showed a longer‐lasting antibacterial activity. The results were verified using a commercially available microbial cell viability assay basing on the measurement of bacterial adenosine triphosphate (ATP) or by counting of colony forming units (CFU) on agar plates.
