The toxic modes of actions by silver nanoparticles were investigated with a panel of recombinant bioluminescent bacteria and compared with the results obtained from gold nanoparticles and silver nitrate. Based upon the changes in the bioluminescence, the silver nanoparticles resulted in a higher cellular toxicity than the same amount of gold nanoparticles. Furthermore, using the stress-specific nature of the promoters, it was determined that the silver nanoparticles cause heat shock and oxidative damage to the bacterial cells, but not DNA damage, while gold nanoparticles did not cause any bioluminescence induction at the same test concentrations. Silver nitrate, used to evaluate differences between the silver ion and the nano-sized silver particles, was also found to causes heat shock damage and oxidative stress within the bacterial cells.
