Application of click chemistry to the production of DNA microarrays

The copper-catalyzed alkyne–azide cycloaddition (CuAAC) reaction was applied as the novel method of DNA immobilization on a modified solid support. The CuAAC click reaction enables the covalent binding of DNA modified with pentynyl groups at its 5′-end to azide-loaded slides. Click microarrays were produced using this approach and successfully employed in biological/model experiments.
