By using Material Safety Data Sheets I have been able to make Forensic Products that work.
I started by using Sirchie Fingerprint Labratories UV734 Invisible Writing Ink. By utilizing a solution of 1.2 parts Leucophor AP (the BSB isn't made anymore) to 98.8 parts distilled Water I have been able to produce a very effective invisible ink that produces a bright blue under UV light.
By taking the same Leucophor AP liquid (that I got sampled from Clariant Corporation) I was able to duplicate Sirchies UV7311 & UV 743E Invisible Metal Marking & Skin Marking Ink. This left an invisible mark for several days on my hand. Then came UV201 Fluorescent Invisible Detection Powder.
By utilizing a mix of 4 parts Green Crayola Powder paint, 64 parts Zinc Stearate & 32 parts Zinc Sulfide(Activated) I have been able to easily make a "theftpowder".
When dusted on a 20$ bill this is almost invisible yet produces a bright green glow on my hand after touching it. After scrubbing my hands underwater I noticed the underneath part of my fingernails still glowed under the blacklight.
This was from one contact, not mixing the powder.
I went on to duplicate UV201-UV207 Theft Powders (a blend of colors for special purpose detection).
Luminol had to be next, part# (Luminol16).
Using a mix of 5 parts 3-Aminophthalhydrazide (purchased from Post Apple Scientific Supply), 85 parts Sodium Carbonate & 10 parts Sodium Perborate Tetrahydrate I have been able to make a dry powder Luminol product that just needs distilled Water added before use.
Currently I've been working on BV100 Blueview Gunpowder Partical Test Kit, a test for gunshot residue.
I have had great success With SPR Spray (small partical reagent), Indestructible Fingerprint Powders, Invisible Crayons, etc.
There is no doubt there are many, many more products that could be copied. I would like to also say that Sirchie is the leading supply to Law Enforcement, so these products are what "they" use.
I would love to hear other recipes for forensic products. I am still very much in the learning stages with this. But I can tell you one thing, the more you use them the more uses they have!
