Soiled: Prototype device and Mobile App

Microfluidic cartridge / Compatible device

By replacing the toxic chemical based laboratory standard of soil analysis with a colorimetric biological analog we can provide a safer alternative. We will genetically engineer E. coli K-12 to express various chromoproteins in the presence of molecules that pertain to soil and plant nutrition. Our plan is to produce a microfluidic chip that will house the necessary reagents, biological or otherwise. Any harmful materials that cannot be replaced will be minimized and sequestered within the device to limit the user’s exposure to potential biological and/or chemical hazards. The microfluidic cartridge will be loaded into a portable device and integrated with compatible technologies, such as a phone and it’s case. The “color data” can be captured and measured by the phone’s camera, eliminating human error. This data will be instantly uploaded into an app that provides accurate feedback regarding what crops are ideal for the current soil conditions and what measures need to be taken to adjust soil for desired crops.
