A self-assembled multilayer (SAMu) including the alginate layer was prepared for detecting Pseudomonas aeruginosa cells in a solution and its potential was evaluated with a BIAcore system. After layer-by-layer formation, the refractive units (RU) values monitored with the biosensor increased by the interaction between the layers. The responses by the binding of P. aeruginosa cells to the alginate-immobilized SAMu were visualized immediately upon injection of the cell suspension. The RU values after injection of the cells were measured with approximately 1152, 656 and 173 for 1 × 109, 1 × 108 and 1 × 107 CFU/ml. This result suggests that the alginate-immobilized SAMu will have useful application for detecting P. aeruginosa cells in a biosensor analysis.
