This source is about using dye to track diseases. It goes into detail about how the dye works and its benefits. It talks about the light spectrum as well.
I will use this to explain how diseases can be tracked. The article uses a lot of numbers and labels that we learned in chemistry so I will use them to connect with the audience.
I will need something more personal about medical research. I am thinking maybe a personal story from someone who has survived cancer or a similar disease.
