Prototype
Our implementation
Concept
The goal of our project was to give consumers a way to determine how far along their milk is in the spoiling process. The idea of using bacteria within a biosensor would create some large health concerns among those we wish to use it. In order to alleviate this concern we worked to develop a way to allow people to see how spoiled their milk is with the use of live bacteria. We came up with the idea to use a cell free system which uses the contents of the cell, in this case our part which would be present in the cell lysate. Our plan is to transfer the contents of the cell onto a piece of paper so consumers would be able to comfortably use it within their homes. In practice this would look like small strips similar to litmus strips that the consumer could buy separately and dip into the milk. The strip would then change color between red and yellow based on how spoiled the milk is. This test strip is, however, only a concept because we ran out of time and could not make it.
