Specifications

Based on the requirements of the medical field (see the section meeting for further details), we set our pathogen detection specifications. So, sEnsiColi should be:

  • Sensitive
  • Reliable (little false positives)
  • Fast
  • Easy to use
  • Lower in price than the current methods.


The modeling part deals with the first three specifications: the deterministic model gives an answer for the sensitivity and the rapidity while the stochastic model gives an answer for reliability.

In this section we will especially deal with the easiness of use and the cost assessment of the device.

Design of sEnsiColi



Regarding the specifications above, we set two possible designs for sEnsiColi.

The first one is intended for prevention purposes such as assessing the contamination level of hospital’s rooms. The design of this detection-kit is given by the picture below:



This first prototype is easy to use: A sample of the surface to test can be taken by a swab and then put in the test tube containing the bacterial solution. After about 5 hours we can check the tube. If we have a fluorescent response then the tested surface is contaminated by Staphylococcus Aureus. (see meetingmodeling section entire module for an assessment of time response)
