week4

The design of the fluorescence array sensor is made like the picture shown below. There are nine different sensor arrays. The material used in the chip is PDMS.

And the results of each ion being tested were predicted by reading the relevant reports, such as the picture below shows how the sensor array would become when there is only Mg²⁺.

We had made the predicted results of five different ions in the waste water. However, this means that we may find only one ion in the water by each sensor from the result. Because we did not take any experiments, it became tough to predict how each sensor array would change when several ions are estimated.

In the next week, the post is to be made, as well as the brief report. And for further research, the information about how to analysis the changed colour of each sensor array is to be found, in order to make a more specific results. For example, we may connect the sensor array to some machine which can analysis the comments of a colour. And according to those changes, we could find out which ions are contained in the waste water by comparing with the predicted results.
