ZnO and hydroxyapatite-based membranes have been proposed to improve the antibacterial properties and anticorrosion capabilities of the magnesium implant, simultaneously. More importantly, the concept of minimally invasive surgery has been introduced to define the degradation timing of the as-modified magnesium implant. With the aid of a Kirschner wire, the as-prepared membrane could immediately change from the "protective layer" to the "degradation accelerator" of the implant material. The subsequent studies have implied that this membrane could be a promising avenue to create a biocompatible and lightweight implant material with a valuable personal customized degradable timing capability.
