Framework

We designed an E.coli biosensor to detect the poison in the Chinese Medicine. When E.coli detects the poison, the device will show fluorescence to quickly warn the user of the existence of poison in Chinese medicine. Our product fulfills most of the requirements and the standards that the government set for detecting toxins/heavy metals in Chinese Medicine. We also innovated design for eco-friendly biosafety guarantee.

1-3 Design of Biosafety

For the safety concern, we innovated a three-step bio-safety guarantee. First, we designed a latch that can lock the E. coli inside the plate when they are loaded. Second, we designed a way, which is no harm to the environment, to prevent the leakage of E.coli from the device, inside of which the inner layer is covered by hibiscus. Hibiscus is a special plant which has great function of bacteria sterilization. We also conducted experiments to verify hibiscus's function of bacteria sterilization.(Figure 2) Third, after use of this device, the user presses a button to inflow sodium percarbonate to the bacteria plate. The interaction of soidum percarbonate with any organic compounds (E. coli in our case) produces hydrogen peroxide, which diffuse into the plate and kill all E.coli. These three steps secure the users safety of use.
