''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 plate placed upon the machine and shined with a blue LED light. When shone upon, the sample's DNA begins to emit a green light; able to be captured with a cell phone camera.''<br>

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>
SYBR Green Dye SBYR green dye is a nucleic acid-sensitive gel dye that is useful in pinpointing double stranded DNA in samples within open PCR machines and other utilities such as the single-drop fluorimeter.

Placing Samples onto the Fluorimeter
Obtain waterproof slides, a Micropipette, and vials of various DNA samples along with a 200 ml vial of SYBR Green solution.
Insert slide into fluorimeter
Turn on blue fluorescent light and make sure that the beam is shined between the first two rows of the dotted slide.
Take 80 micro-liters of SYBR Green solution into micropipette
Release all of the 80 micro-liters of SYBR Green fluid onto the slide, then ensure that the beam of light hits the droplet.
Take another 80 micro-liters of DNA Sample and extract into the SYBR Green droplet. Make sure the drops form a ball and doesn't spread around making individual droplets all over the slide.
After the photo shoot is complete, calibrate the micropipette to 160 micro-liters and extract all of the sample on the slide.
Repeat the same steps for the additional DNA Samples.
