The total amount and distribution of the Ar+, Cu+ and Cu2+ ions were determined as well as the bacterial inactivation kinetics mediated by DCMS and HIPIMS samples. The separation of extracellular and intracellular processes leading to bacterial inactivation was assessed on normal and genetically modified E. coli.Chemistry, PhysicalMaterials Science, Coatings & FilmsPhysics, AppliedPhysics, Condensed MatterChemistryMaterials SciencePhysicscu-polyestermagnetron sputteringcu-ionsporinless bacteriabacterial inactivationsurface-contact effecthydrogen-peroxidesurfaceswatertext::journal::journal article::research article
