A versatile and stable liposomal platform is developed for rapid optimization of its peripheral composition. The platform is based on polydiacetylene lipids terminated with alkynyl groups. Conditions for copper-catalyzed azideâalkyne cycloaddition (a âclickâ reaction) are optimized for rapid attachment of azides with controlled composition onto the liposomes.
Anaerobic conditions to reduce oxidation of proteins and to accelerate the copper-catalyzed “Click” reaction with a water-soluble bis(triazole) ligand

Oxidation of protein (bovine albumin serum) by air still occurred under the copper-catalyzed azideâalkyne cycloaddition (CuAAC) reaction conditions even in the presence of a Cu(I)-stabilizing tris(triazole) ligand. Anaerobic conditions not only avoided the oxidation of the protein, but also greatly accelerated the CuAAC reaction using a water-soluble bis(triazole) Cu(I) ligand.
