Hello,
After reading your post, I was curious as I had never heard of this method. I have tried to make a mixture of crystalized R6G and CA, which yielded no fluorescent properties, I also attempted to mix a pre-mixed R6G with CA and again no results. Our labonly uses a liquid dye stain following CA fuming as of now. Good luck with your thesis.

Hello! Im a swedish student writing my thesis at the Laboratory of Forensic science in Sweden. Ive been reading publications about different dyes that have been mixed with cyanoacrylate or fumed on the latent fingerprint concurrently with cyanoacrylate to enhance the visualization of latent fingerprints. I wonder if there are any forensic laboratories who use these one-step-methods instead of using solutions of dyes like basic yellow after fuming with cyanoacrylate? And if there are not, I wonder why not? Id be very glad if someone could help me with these questions or maybe give me a contact to some one who can.. Kind regards!
