A method of creating biocompatible polymeric structures includes the steps of: providing a biocompatible polymer including a strained cycloalkyne end group; forming a polymeric structure from the biocompatible polymer such that the strained cycloalkyne end group remains on the biocompatible polymer; providing an azide tethered molecule; and, after forming the polymeric structure, reacting the azide tethered molecule with the cycloalkyne in an azide alkyne cycloaddition reaction to further functionalize the polymeric structure.

A primary amine-derivatized 4-dibenzocyclooctynol (DIBO) was used to initiate the ring-opening polymerization of poly(gamma-benzyl-L-glutamate) (DIBO-PBLG). This initiator yields well-defined PBLG polymers functionalized with DIBO at the chain termini. The DIBO end group further survives an electrospinning process that yields nanofibers that were then derivatized post-assembly with azide-functionalized gold nanoparticles. The availability of DIBO on the surface of the fibers is substantiated by fluorescence, SEM, and TEM measurements. Post-assembly functionalization of nanofiber constructs with bioactive groups can be facilitated easily using this process.
