Abstract

A novel bionanotechnological method for fabricating magnetic nanotubes with the aid of magnetic bacteria was investigated. Magnetospirillum magneticum strain AMB-1 was selected as a model to immobilize the extracted bacterial magnetic nanocrystals on the peptide nanotubes. Then, the magnetic nanocrystals were separated by using a magnet placed at the bottom of the glass tube containing the disrupted cells. The main advantage in using bacterial magnetic nanocrystals is that the mineral type, crystal size and morphology of the magnetic nanocrystals can be controlled by the selection of the bacterial species or strains.
