Objects identified by a DNA code

As part of Dominique Peysson's artistic residency at Espace Jean-Roger Caussimon in Tremblay-en-France, in partnership with Lieu Multiple, the DNA school and the Ebi-Carbios laboratory in Poitiers and supported by the Seine-Saint-Denis Department and the Ile-de-France Region.
DNA in plastics was exhibited from January 5 to March 10, 2017 for the Première Impression exhibition, consisting of 5 of my works on DNA.

My idea is to use the coding power of DNA in my own way, to mark objects that we wish to be able to authenticate. Nothing could be simpler: just mix the source material with a very short synthetic DNA that I had made. As for the quantity to put in, of course I choose to mix the same proportion of DNA as in our own body, that is 0.4% by weight of the final object. The analysis of this small piece of DNA will thus give me the exact identity of the origin of my object.

I have created a pictorial representation system of the ATGC list of letters that will make up my little pieces of DNA. A color code is associated with each letter. A solid square subdivided into 25 small colored squares makes it possible to visualize at a glance the order of the nucleotides. The square of 5X5 color units is similar to QR codes.


It can also be very simply associated with a classic black and white QR code, by establishing a simple relationship between each color and a subdivision of small black and white squares. The color QR can therefore easily redirect to a website, on which it is possible to refer for the object in question.

All plastic objects could thus be marked and authenticated by this DNA of objects...
