A Cu-free clickable polymer was synthesized and used to dip-coat plastic substrates to prepare Cu-free clickable surfaces. The surface density of dibenzocyclooctyne moieties was quantified using an azide-conjugated fluorophore and a conventional fluorometer, indicating that the clickable moieties displayed on a dip-coated surface were accessible from solutes in water. The present approach also succeeded in the control of the surface density of the clickable moieties.Azide-conjugated oligo DNA was immobilized on the surface using a Cu-free click reaction.

In the original published version of Fig. 1, the chemical structures of PFEA8 contained-(CH 2) 7in the side chains of PMFP and poly(MMA-r-PFEA8). They have now been corrected to-(CF 2) 7-. The corrected Fig. 1 is as shown below.
