Antigen analogs of polyclonal antibodies specific for type A Neisseria mengitidis are prepared by covering gold clusters (2–5 nm in size) with a monolayer of saccharides that have the structure of the repeating unit of the capsular polysaccharide of this bacterium. These systems may find use as synthetic antigens for immunostimulation.
