I am trying to devise a streategy on how to use the streptavidin/biotin interaction on a graphene-coated surface. I am thinking of coating the surface with streptavidin, but I need to be able to re-use these slides and either remove the streptavidin or unbind all streptavidin-biotin interactions off the surface. In the later, the streptavidin would need to be functional or I would an option that removes the streptavidin off the surface as well. Any ideas for someone who is more with surface chemistry?
