In mimicking the chemical structure of collagen nanofiber, electrospun polyacrylonitrile nanofibers were hydrolyzed to generate amide and carboxyl groups on the fiber surface. These fibers were applied as templates in bio-mimicking the growth of hydroxyapaptite (HAp). Nucleation and growth of HAp crystals were fast, and bioactive HAp/fiber composites were produced. The composite scaffold was non-cytotoxic to human dental pulp stem cells.
