Assembly of BactoMotor

Introduction

Our BactoMotor is comprised of three parts – the Micro-Motor; the Directional Controller and the 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 (for the Directional Controller Module).

'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)

Fig.4: Bacteria not binding to the Micro-Motor will be flushed away by medium flush.

'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)
