Permanent seed brachytherapy, a treatment for prostate cancer, is a minimally invasive procedure; however, it may cause radiation-induced adverse events such as urinary frequency and bleeding. In this study, we focused on zinc-containing amorphous carbon (a-C:Zn) films that release zinc, which has been reported to suppress cancer cell proliferation, and explored their potential application in prostate cancer therapy. As a fundamental evaluation, the effects of ultraviolet sterilization time on the structure and surface properties of a-C:Zn films were investigated, and the stability of the films against sterilization treatment was assessed.
