Advantages of highly ionized pulse plasma magnetron sputtering (HIPIMS) of silver for improved E. coli inactivation

► Ag-layers sputtered by HIPIMS to inactivate E. coli are thinner compared to DC magnetron sputtering. ► HIPIMS leads to Ag-metal saving a non-renewable resource of industrial importance. ► Microscopy images of DCMS and HIPiMS Ag-clusters on a fiber are presented
