  • In this project our aim is to transport specific metal ions from a specific location to another on the surface of engineered bacterial cells. In other words, to use cells as metal carriers.

We didn't want the metal ions to be uptaken by the cells since we want to transport specific metal ions (eg. radioactive ones) so we focused on putting metal-binding domains on the surface of the bacterial cells. This can be done by adding short metal-binding domains to bacterial constitutively expressed transmembrane proteins such as LamB or OmpC.
