Abstract

The copper-free azide-alkyne click reaction has shown to be a successful alternative to immobilize covalently a fluorescente compound onto poly(-l-lactic) acid (PLLA) surfaces. Proceded by basic hydrolysis and amidation reaction, typical surface characterization techniques have validated each functionaliztion step and the success of the conjugation. This method offers a catalyst-free option for various surface conjugations, extremely demanded in biomedical and biosensory fields.
