Abstract:
Citric acid, a molecule present in fresh bone, was introduced into template-free electrochemical polymerization to form biocompatible coating made of polypyrrole (PPy) nano-cones on bone implants. It served not only as a dopant to tune the nano-architectures but also as a promoter to enhance bioactivity of the PPy-coated implants.
