Principe of microcontact printing of DNA molecules. (1) Inking of the stamp with the oligonucleotide solution, a 1 cm2 stamp is loaded with a 2 to 20 μl droplet of solution for a given time (2) drying of the stamp under Nitrogen stream, (3) manual contact between the inked PDMS stamp and the glass slide, (4) probe molecules are transferred on the slide along patterns that correspond to the relief structures of the PDMS stamp.
