Procedure
Smart Phone Camera Settings
Type of Smartphone: Apple iPhone 5S
Flash: Off
ISO setting: Auto
White Balance: Auto
Exposure: High
Saturation: High
Contrast: Low
Calibration
The camera was set up by placing the iPhone 5S in the holding compartment of the lab equipment. It was measured to be 6 centimeters away from the origin of the light emission. The settings (stated above) were adjusted; the height of the fluorimeter was adjusted in order to achieve a perfect side-angle perspective of the "beach ball" shaped liquid drop.
Distance between the smart phone cradle and drop = 8 centimeters
Solutions Used for Calibration
Initial Concentration of 2X Calf Thymus DNA solution (μg/mL)
Volume of the 2X DNA solution (μL)
Volume of the SYBR GREEN I
Final DNA concentration in SYBR Green I solution (μg/mL)

Placing Samples onto the Fluorimeter
Before placing samples onto the fluorimeter, turn on the Blue LED light & have the camera on the smartphone ready.
Insert the glass sampling surface, with the smooth side facing down.
Position the glass sampling surface so that the light emits between the first two rows of the glass.
Place an 80 μL drop of SYBR Green I in the middle of the first two rows.
Swap out the pipette tip with a new tip.
Place an 80 μL drop of a specifically concentrated Calf Thymus DNA solution onto the top of the previously placed SYBR Green I drop. Every three 160 μL sample drops will vary in concentrated Calf Thymus DNA solution.
In order to place a new sample drop, remove the 160 μL solution, move the glass sampling surface to the next two available rows, and repeat the process of placing two new 80 μL drops onto each other (as stated before).
