single-atom catalysts (SACs) with individual and isolated metal atoms anchored to supports can act as active centers. Single-atom catalysis is powerful and attractive because SACs have demonstrated distinguishing performances, such as drastic cost-reduction, notable catalytic activity, and selectivity.

I suggest you to have a look at the following papers too:

I do not seem to have said that Single Atom Catalysis (SAC) is not relevant in ELISA coating, I have only reported some recent articles that described the methodology, the potential and the general perspectives. I apologize, neglecting any details, I could not be of help to you.
