Synthesis and Fabrication of Surface-Active Microparticles Using a Membrane Emulsion Technique and Conjugation of Model Protein via Strain-Promoted Azide-Alkyne Click Chemistry in Physiological Conditions.

The rapid surface immobilization of protein on monodispersed polyester microcarriers is reported. A model protein, functionalized with a dibenzocyclooctyne core, immobilizes on the surface of azide-terminal polycaprolactone microcarriers within 10 min compared to 12 h for other conjugation techniques, and it is conducted in physiological conditions and in the absence of coupling reagents.
