DNA sequences were modified as reported (amine and azide linkers were linked at 5' end, while DBCO and biotin were linked to 3' end or 5' end. Stabilizer DNA sequence was used without modification. Table The immobiline buffer was dried under reduced pressure and all the monomers were suspended in 0,5 mL of anhydrous THF. To the resulting reaction mixture was then added AIBN (5 mg) under argon atmosphere and the polymerization was conducted at 65°C for 2 hours.
