Outline of Final Research Achievements

We have found that a high density structure of metal nanoparticles acts like an
excellent antenna owing to its optical properties, which permit sensitive detection of bacteria and analysis of a single bacterial cell. By using antibodies, these antennas can be engineered to recognize only specific bacterial species. This system provides a new technique that will allow a more sensitive detection of specific bacteria.
