摘　　要：An agglutination test based on colored silica nanoparticles(colored SiNps) was established to detect serotypes of Pseudomonas aeruginosa. Monodisperse colored SiNps were used as agglutination test carriers. The colored SiNps were prepared through reverse microemulsion with reactive dyes, sensitized with 11 kinds of mono-specific antibodies against P. aeruginosa, and denoted as IgG-colored SiNps. Eleven kinds of IgG-colored SiNps were individually mixed with P. aeruginosa on a glass slide.Different serotypes of P. aeruginosa could be identified by agglutination test with evident agglutination. The P. aeruginosa could be detected in a range from 3.6×10^5 to 3.6×10^12 cfu mL^–1. This new agglutination test was confirmed to be a specific,sensitive, fast, easy-to-perform, and cost-efficient tool for the routine diagnosis of P. aeruginosa.An agglutination test based on colored silica nanoparticles（colored SiNps） was established to detect serotypes of Pseudomonas aeruginosa.
