Background: Reactive oxygen species (ROS), particularly hydroxyl radicals (•OH), contribute to oxidative
stress, leading to biomaterial degradation and cellular damage. The ability of metallic implants to resist
oxidative stress is crucial for their longevity and biocompatibility. This study evaluates the antioxidant
potential of PTFE-coated stainless steel alloy extract through the DPPH radical scavenging assay. Methods:
The scavenging effect of PTFE-coated stainless steel was evaluated by comparing absorbance values with
controls. In parallel, the DPPH assay was performed by incubating PTFE-coated stainless steel alloy extract
and untreated alloy extract with DPPH solution, with absorbance measured at 517 nm to determine radical
scavenging activity.
