Title:
ANTIBACTERIAL BIOLOGICAL IMPLANT
Document Type and Number:
WIPO Patent Application WO/2018/179357
Kind Code:
A1
Abstract:
Provided is an antibacterial biological implant capable of stable display of excellent antibacterial properties over time. This antibacterial biological implant 1 is provided with a substrate 2 made of a metal material and an anodized coating 3 layered on the substrate 2. The anodized coating 3 has an iodine-rich layer 31 disposed on the side of an interface S with the substrate 2.
