Would this be the right section of the forum to put this?
I've been looking into glow in the dark materials and basically they are all toxic to an extent to the human body. However there is a thing called microencapsulation which basically takes a small portion of a material and coats it with something else. This can be done on a very small scale which could then be mixed with a carrier and used as an ink.
The questions I have would be would the body try to absorb it and why doesn't this happen with normal ink?
Also does anyone know anything about microencapsulation and if it could be done on a smaller scale (not entirely home made stuff but smaller than huge industry)?
What materials are nonporus and biocompatable that could be used to coat it?
