The efficacy of 15 nm gold nanoparticles (AuNP) coated with Yersinia pestis F1-antigen, as an immunogen in mice, has been assessed. The nanoparticles were decorated with F1-antigen using N-hydroxysuccinimide and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide coupling chemistry. Mice given AuNP-F1 in alhydrogel generated the greatest IgG antibody response to F1-antigen when compared with mice given AuNP-F1 in PBS or given unconjugated F1-antigen in PBS or alhydrogel. Compared with unconjugated F1-antigen, the IgG2a response was enhanced in mice dosed with AuNP-F1 in PBS (p
