WatsOn

Aachen Device 11.jpg
'

Part of the biosensor system Cellock Holmes are our agar chips. They contain our engineered sensing cells that fluoresce in the presence of the pathogen Pseudomonas aeruginosa. However, bacteria are small and the fluorescent signal cannot be seen with the naked eye. Thus the central question "What's on the chip?" remains.

To answer this question we present our measurement device WatsOn.

Functions

WatsOn fulfills several tasks in our system:

  • incubate the sensing cells and the sampling chip
  • prevent escape of potentially sampled pathogens and our genetically engineered cells
  • illuminate the chip with the right excitation wavelength for GFP or iLOV
  • take photos and timeseries of the chips
  • analyze the fluorescence signal
  • give feedback to the user about the presence or absence of P. aeruginosa

WatsOn is designed such that it can be easily copied. Our work heavily emphasizes the Open Source concept. Therefore, the construction manual and all technical detailes are published on our wiki. Analogous to our OD/F device, we used low-cost and easily available parts.

Aachen Device Fritzing.png
Wiring of our device
Aachen Device 1.jpg Start building your own WatsOn by assembling the base plate, the sides and the interior wall.
350px] [File:Aachen_Device_.3jpg Fix the Peltier heater on the back of the aluminum block and place it in the hole of the interior wall.
Arrange the 4x4 450nm LEDs and the 2x3 480nm LEDs
Aachen Device 7.jpg Assemble the camera holder with the camera and the corresponding filter slide on the lower part. Over the camera you can place the temperature sensor for measuring the indoor temperature. Finally put the fan on the back of the camera holder.
Aachen Device 8.jpg Connect the electronic components on the outside and the inside according to the wiring diagramm.
Aachen Device 4.jpg Put together the drawer.
Aachen Device 9.jpg Position the front panel and insert the drawer.
Aachen Device 10.jpg Place the temperature sensor for the aluminium block temperature directly on the block and put the back panel in front of it.
Aachen Device 6.jpg Setup the power supply and connect all devices to either 5V or 12V.
Aachen Device 11.jpg Mount the device on top of the power supply casing. Add the display and apply some stickers to enjoy your custom-made WatsOn.
