摘要: Amino acid-based poly(ester urea)s (PEU) are emerging as a class of polymers that have shown promise in regenerative medicine applications. Embodiments of the invention relate to the synthesis of PEUs carrying pendent “clickable” groups on modified tyrosine amino acids. The pendent species include alkyne, azide, alkene, tyrosine-phenol, and ketone groups. PEUs with Mw exceeding 100k Da were obtained via interfacial polycondensation methods and the concentration of pendent groups was varied by copolymerization. The incorporation of derivatizable functionalities is demonstrated using 1H NMR and UV-Vis spectroscopy methods. Electrospinning was used to fabricate PEU nanofibers with a diameters ranging from 350 nm to 500 nm. The nanofiber matricies possess mechanical strengths suitable for tissue engineering (Young's modulus: 300±45 MPa; tensile stress: 8.5±1.2 MPa). A series of bioactive peptides and fluorescent molecules were conjugated to the surface of the nanofibers following electrospinning using bio-orthogonal reactions in aqueous media.
