/? Graphene laser fruit peel: https://www.google.com/search?q=graphene%20laser%20fruit%20p...
They apply the ink/dye to a surface and then use a laser on it, leaving the graphene behind.
I still don't understand why that's only possible with commercial inks and dyes but not with also aromatic fruit peels?
