Re: [DIYbio] Re: Chemical autoflorescence in fish

Fluorescence is far more common than most people realize.

If you obtain a 405 nanometer (violet) laser pointer, you can detect fluorescence in wines, beer, wood, chlorophyll, and many other natural objects and substances.

It makes a good party trick.

Think of all the detective shows that use black lights to detect semen and urine on bedsheets.

People bring black lights to motels to check bathrooms for effective house cleaning.

Blue fluorescent dye is used in laundry detergent to make yellowed clothing look white.

The dye adheres well to most fabrics. I would expect it would also adhere well to fish scales.

Bring your black light into the laundry room and look at all of the splashes on the walls.

Any guess what this could be?

The site claims the fish is not GMO and they are not tattooed. Somehow the dye, whatever it is bonds to calcium rich biominirals. Bone, shell, etc.
