Title:
METHOD FOR PRODUCING ANTIBACTERIAL BIOLOGICAL IMPLANT
Document Type and Number:
WIPO Patent Application WO/2018/179358
Kind Code:
A1
Abstract:
Provided is an antibacterial biological implant capable of stable display of excellent antibacterial properties over time. In this method for producing an antibacterial biological implant, an antibacterial biological implant 1 is obtained by performing an anodization treatment, an acid treatment and an iodine treatment on a substrate 2, in that order.
