ENGINEERING

In order to fully automate the whole biological process we need to be able to perform 4 main actions :

  • pipette liquid in and out of Eppendorf tubes

  • heat and cool samples

  • extract DNA after the lysis step

  • measure the fluorescence at the end of the process in order to know the results of our diagnostic

    To control those actions we use:
  • an Arduino microcontroller to handle the different electronic components
  • a raspberry pi (a very small and cheap computer) to display the results and interact with the user

The whole process takes place in a structure made of aluminum and Plexiglas. The samples, buffers and pipette tips are placed on a central rotating plate that moves thanks to a motor controlled via our Arduino.

This circular structure is very convenient as:

  • it optimizes the space used
  • it does not require to move the different modules, reducing the complexity of the system.
