Assembly of BactoMotor
Introduction
Our BactoMotor is comprised of three devices –Micro-Motor,Directional Controller and Speed Controller.
As their names indicate, the Micro-Motoris the core part of the BactoMotor, and it is small (micrometer scale). The Directional Controller ensures directional propelling force generated by the bacteria, and therefore directional rotation of the motor. The Speed Controller is used to implement a speed control over the motor.
Each device is designed, engineered and tested seperately. All are functional on their own. After testing and fine-tuning, the devices are assembled to form the final System BactoMotor. As a result, we would have a micrometer-scale BactoMotor with unidirectional rotation and speed controller.
Prodecures
Step 1. Installation of Micro-Motor
The Micro-Motor will be installed into a microchip container (Fig.1a, 1b) with separated chambers. Only one side of the arms of the motor is coated with Biotin (see the Directional Controller).

Step 2. Introduction of Bacteria
The Bacteria with both Directional Controller and Speed Controller Modules implemented will be introduced to the Micro-Motor (Fig.2).
Step 3. Action of Directional Controller
Under the effect of the Directional Controller, the Bacteria will bind onto the Micro-Motor directionally. (Fig.3a, 3b)
Step 4. Removing Excessive Bacteria
The extra bacterial cells will be removed by medium flush. (Fig. 4)
Step 5. BactoMotor in Action
As the Bacteria swims, they will push the motor into rotation. (clockwise as demonstrated in Fig. 5a, 5b)
Step 6. Using the Speed Controller
To utilize the Speed Controller Module, an inducer is added to the Microchip containing the Micro-Motor. Increase in concentration of the inducer will lead to an overall increase in rotational speed of the Bacto-Motor. (Fig. 6a, 6b)
