Recent clinical trials were conducted using V-B Armor on surgical implant washers and screws. 
Both the untreated and treated washers and screws were exposed to Staph MRSA. The washers and screws treated with V-B Armor antimicrobial showed no signs of microbial growth. The untreated washers and screws had microbial growth. It is not difficult to distinguish from the pictures which were the treated ones and which ones were not.
