Formula
Stock Solution:
​1 g M.B.D. powder dissolved in 1 liter Acetone

M.B.D. Working Solution (Combine in the order listed): 
10 ml M.B.D. Stock Solution
30 ml Methanol
10 ml Isopropanol
​950 ml Petroleum ether






​
Procedure of Application
  1. Spray, immerse or use a squirt bottle to apply the M.B.D. solution to the item.
  2. View under a Forensic Light Source in the 435 nm to 535 nm range. Use orange colored goggles.
  3. Photograph results using orange barrier filter.







​
​
Development Complete When
The cyanoacrylate has absorbed the dye stain.







​

​



​
Source of Error
Surfaces that absorb too much dye stain will fluoresce too brilliantly to be effective for photography.






​





​
Incompatibilities
Items that inherently fluoresce in the 515 nm range will interfere with the dye stain fluorescence.









​


​
Precautions
Avoid excess build-up of cyanoacrylate, since this may result in ridge detail depicting little contrast to the strongly fluorescent surface.








​


​
Storage Container
Dark stoppered glass or plastic bottles.







​





​
Safety
Fume hood use is required when preparing and applying this reagent.









​


​
Recommendations
The recommended procedure of application is to immerse the item in a tray of the dye.

A rinse using Methanol may be necessary to reduce excessive staining by the dye.

Process Summary:
A fluorescent dye-stain used to enhance cyanoacrylate-developed latent prints. A fluorescent light source that will output light between 435 nm and 535 nm is required for this process. ​

Accepted Deviations:
The wavelength at which fluorescence is optimized is adjusted in accordance to the personal preference of the examiner. ​
