1-23. (canceled)
A method for presenting a coating formulation to a surface, the coating formulation comprising selenium and a selenium attachment agent, the method comprising the steps of:
- coupling at least one reactive anchor group to at least one activated atom present on the surface;
- and
- tethering the at least one reactive anchor group to at least one biocidal group or a functional group capable of secondary reaction to the at least one biocidal group.
An anchor group comprising a dipodal reactive group attached to a dimethacrylate.
A selenium attachment agent comprised of a spacer possessing a rigid framework for a preorganized 3D motif for maximizing the spatial proximity of a selenium group and for close packing on a surface, the selenium attachment agent comprising at least one of the following structures:
- wherein A is at least one of vinyl, acrylate, methacrylate, silane, and combinations thereof;
- wherein R is an alkyl or aryl linker;
- wherein R′ comprises an aliphatic or ether residue terminated with alcohols, amines, carboxylic acids, silanes, phosponate, sulfonate or phenols;
- and
- wherein X is a protecting group selected from the group consisting of a halogen, an imide, a cyanide, an azide, a phosphate, a sulfate, a nitrate, a carbonate, selenium dioxide, and combinations thereof.
A method, comprising:
- creating a redox—cycle facilitator atom or group in proximity to a catalytic site of a diselenide.
