Size and structure of the Au nanoclusters formed on Cells and S-layer of Bacillus sphaericus JG-A12

Cells and S-layer sheets of B. sphaericus JG-A12 were used as templates for the deposition of metallic gold nanoclusters using dimethyl amino borane (DMAB) as reducing agent . Gold LIII-edge XAS measurements confirmed the formation of Au(0) nanoclusters in both cases. In this Talk, the preliminary results on the size and the structure of the Au nanoclusters deposited on cells and S-layer protein of B. sphaericus JG-A12 will be presented.
