Development and implementation of analysis program for Peritrichous bacteria-based nanorobot (bacteriobot)

This paper proposed an analysis program which can filter the moving phase of Peritrichous bacteria and analyze the rotational motion of a bacteria-based nanorobot (bacteriobot) with a spherical body. Using this program, the chemotactic steering of Salmonella typhimurium was quantitatively analyzed. The program used the bacterial running phase only to obtain an exact direction of the bacteria. As another implementation of this program, the motility of a bacteriobot which consists of an alginate microbead and flagellated bacteria has been analyzed. It showed a slow translational velocity and a relatively high angular velocity of a bacteriobot with a single attached bacterium. These results mean the propulsive force of a single bacterium gives some torque to the microbead. Therefore, the bacteriobot needs an additional external sources for an efficient translational motility such as chemical gradients, light intensity and magnetic fields.
