Reversible immobilisation of engineered molecules by Ni-NTA chelators

In this paper graphite or gold working electrodes obtained by several deposition techniques were used as substrates for electrochemical synthesis of Ni-NTA chelators. obtaining higher immobilization yields (increased 50 fold), lower treatment time (5 min) with respect to the chemical treatment (12h), and ability to address the synthesis on only one electrode in a sensor mu-array.
