"Dandelion" Inspired Dual-Layered Nanoarrays with Two Model Releasing Features for the Surface Modification of 3D Printing Implants.

Inspired from dandelion, dual-layered ZnO nanoarrays were modified on the surface of 3D printing implants to reduce the postoperation infective rate. According to both in vitro and in vivo tests, it exhibited unique two model-releasing features which could be applied to 3D printing implants as a healthier alternative to antibiotics.
