Stainless steel is a frequently used and cost-effective material. In this study, we discovered for the first time that fresh 316ss possessed an intrinsic peroxidase (POD) catalytic activity, which can catalyze the substrate of POD-like reaction 3,3',5,5'-tetramethylbenzidine (TMB) changing to a blue-colored product, oxidation of TMB, in the presence of hydrogen peroxide (HO). Subsequently, a rapid method was conducted to enable the active composites of the 316ss with reused POD activity for 25 circles at least. Read More
