To insure authenticity of various things, they could be marked with microcapsules covered with certain proteins that would attach to various antibodies. The antibodies would be marked with substances that fluoresce.
Alternatively, the micro-capsules could be filled with encoded DNA where the DNA
contains an authentication code. To verify authenticity, a swab is taken from the article and placed in a solvent to dissolve the micro-capsule. The DNA is then "amplified" by means of PCR (polymerase chain reaction) so there is enough DNA to analyse.
