As shown above, even a single cell is capable of increasing fluorescent protein concentration to several micromolar. In tests with the ADK, a concentration of 0.1 Molar was detectable by the ADK.

Although separating each part of the biosensor is important for testing, it is perhaps more important that the part be able to function in an environment that contains various levels of many analytes.

An unintended result of the system, our biopart actually decreases lead concentration as it binds to the Lead Binding Protein and activates Superfolder GFP production. <br> | Although separating each part of the biosensor is important for testing, it is perhaps more important that the part be able to function in an environment that contains various levels of many analytes.

In the future, the biopart could be expanded to detect more substances, even to the point of becoming a nearly-universal reporter for potentially harmful substances. This would obviously extend the applications even further, using synthetic biology for detection of nearly any substance. | In the future, the biopart could be expanded to detect more substances, even to the point of becoming a nearly-universal reporter for potentially harmful substances.

Results and Discussion
In conclusion, our results demonstrate that the biopart created is capable of sensing the targeted analytes. As shown in the graphs below, fluorescent protein concentration increases rapidly in the first few minutes after exposure to the analyte. As protein degradation and translation reach equilibrium, the level of protein remains constant. As Tinkercell incorporates cellular processes such as mRNA degradation, movement within a cell, and transcription rates, the model is highly accurate. For the initial concentrations of each substance, the lowest level considered “dangerous for human consumption” by the EPA was used. For lead, this level was 15 parts per billion, and thus this concentration was used. This was the same for phosphates (100 parts per million), nitrates (10 parts per million), and copper (1.3 parts per million). Fluorescent protein concentrations are given in micromolar.
As shown above, even a single cell is capable of increasing fluorescent protein concentration to several micromolar. In tests with the ADK, a concentration of 0.1 Molar was detectable by the ADK. With many cells in local environment reacting to the presence of one of the targeted substances, it can be concluded that enough fluorescence would be produced to activate the ADK response. The graphs below demonstrate the results of lab tests using GFP (about 2/3 as bright as the Superfolder GFP used in the actual biopart) at a concentration of 0.1 Molar. As shown, the detection of green light increased significantly, to the point where the ADK would register a change in light.
