Things That Go Here
- The Paper-Test and the iterations
- The Discussion of Assays used to test
Paper Based-Assay Design
The final product started with a simple early prototype. Before setting out to create this product, creteria needed to be set. This led us to create a table for our design criteria
| Customer Need | Technical Need | Technical Requirement | Target value |
|---|---|---|---|
| The test should give results fast | How fast the reaction occurs once the sample is applied | *Insert data from survey | *Insert data from survey - x |
| The test should be cheap | The test needs to cost little USD | The test should cost less than x1$ to make (data from survey) | The test will be less than x2$(amount less than x1) to make. |
| The test should be easy to use | Test will require little steps top use | Test will have less than x1 steps | Test will have less than x2 steps |
| Test needs to be able to be shipped worldwide | Test can last several days after creation | test can last X days | test will last x2 days |
| test needs to be accurate | Test will very sensitive | Test will have x% sensitivity | test will have less than x% sensitivity |
Now that we know what our targets are, it is time to come up with several designs. One important question asked was if it is better to have 2 different designs or one test that could detect for both. This led to a variety of designs. There could either be a 2D design or 3D design. . Early designs looked a little bit like the following However, after meeting with Dr.Linnes, an assistant professor at Purdue University in the department of Biomedical Engineering, our team decided on different designs 3D assays for our Farnesol detection. At the time the chosen design was the following
Our team found in scientific literature different methods for testing designs. Our team decided that one of the best approaches was to use series of printed 96 well plates. The very first few printed was used to test our design of the 96 well plates. We were testing to see if there were any leaks of water flowing through different wells. After we tweaked our design, we began to model our different tests that would mimic our final design. After using the data and incorporated our model, we were able to print a few of our final designs in order to do sensitivity analysis as well as durability of the design.
The next step after testing was to evaluate our designs using a decision matrix. This is seen below

Design
Design is the first step in the design-build-test cycle in engineering and synthetic biology. Use this page to describe the process that you used in the design of your parts. You should clearly explain the engineering principles used to design your project.
This page is different to the "Applied Design Award" page. Please see the Applied Design page for more information on how to compete for that award.
What should this page contain?
- Explanation of the engineering principles your team used in your design
- Discussion of the design iterations your team went through
- Experimental plan to test your designs
