''The single-drop fluorimeter is a fluorescence-based DNA detection device that aids in bringing to light PCR-Amplified DNA. The DNA sample is placed on a slide upon the machine and shined with a blue LED light. When the light hits the sample, the sample's DNA emits a dim green glow. From there, under a controlled, light-limited environment, a camera (specifically a camera on a phone) can be used to capture the green light.''<br> | ''The single-drop fluorimeter is a fluorescence-based DNA detection device that aids in bringing to light PCR-Amplified DNA.

'' | ''The overall procedure of the fluorescence technique consisted of an extremely hydrophobic (water-hating) surface. This was used in order to not allow any water to be absorbed during the experiment. The slide atop was coated with an adhesive cover in order to keep the molecules in place during analysis, and keep them a certain distance from the slide at the same time. This being so, it alloweed for the blue LED light to be focused in the drop; causing an increase in intensity which helped create the fluorescent environment. In addition, The SBYR Green dye that was added with the solvent helped form a complex with DNA that preferred to stick to the surface than anywhere else on the Fluorimeter. If a water-soluble dye was used instead, the outcome of the experiment would differ because instead of the green glow, a colorful beam of light would have shown through. | ||
*Note that the group used SYBR Green due to the fact it seemed to be the most eco-friendly." | |||

The iPhone was placed in a cradle in a way that made the lens the same height of the fluorimeter. In order to make them the same height, glass platforms were placed to raise the height of the fluorimeter. The distance was around 8 cm. The whole system was placed under the dark box and the pictures were taken. This was repeated for each new solution. | |||
