Is the human skin flake fluorescent?

01 January 1970 1 2K Report

I am using a laser-induced fluorescence instrument to monitor the bioaerosol in the indoor environment. I wonder if the skin flake can be detected. Does it have any chemical that can be excited at 280 nm or 350 nm and fluoresce? Thnx!

Hugh J Byrne

Fluorophores in skin can be nicotinamide adenine dinucleotide (NADH), collagen,

elastin, tryptophan, flavins, melanin and porphyrins. The question is which are present in the skin flakes!
