On the one hand we are using E.coli as genetically modified organism and on the other hand we are detecting Pseudomonas aeruginosa a human pathogen. While using Pseudomonas we have the problem of non-proliferation. For E.coli we have to look after the non-release of genetically modified organisms. In general we developed and designed the measurenment device as closed system for a better safety handling. In this way neither the sampled pathogens nor the genetically modified sensor cells can escape out of our biosensor unit. Also the electronic components are inaccessible so that no one could get an electric shock. For the detection we are using one way sampling and sensor chips which can be disposed after autoclaving or irradate them with a strong UV light. |

For this procedure open the drawer of the measurement device and pour bacillol on the sampling and also on the sensor chip. After this measures both chips can be autoclaved and later disposed. The whole lining of the measurement device is build on plastic so it could be desinfected completly. |
For the worst case scenario we made a stamp pront of the used sensor chip. In three experiments we got an arithmetic mean of five colonies which could get out of these chip. To conclude the infection risk is really low if you are not using the measurement device as descripted. | For the worst case scenario we made a stamp pront of the used sensor chip.
