Overview

We designed an inexpensive and easy to use fluorescence detection system with Arduino. By simply putting the sample to our container and put it in the device, four kinds of data from the same sample can be detected. What’s more, the inner components are designated to change easily, so that other iGemers can modified it to fit their purpose.

Usually, bubbles occurred when the sample taken up increase the fluorescence detection error. However, our device took advantage of capillary phenomenon to get the sample to fix this bubble problem.

As for the optical system, we use a green filter, a led light, two convex lens and a photodiode. Those thing are inexpensive and successfully detect the fluorescence.
