  • Title: The release of cupric ion in simulated uterine: New material nano-Cu/low-density polyethylene used for intrauterine devices.
    Author: Xu T, Lei H, Cai SZ, Xia XP, Xie CS.
    Journal: Contraception; 2004 Aug; 70(2):153-7. PubMed ID: 15288221.
    Abstract:
    With the development of IUDs, a number of copper-bearing devices are now commercially available, including the copper-T, the Multiload and the copper-T in various other forms, so-called "the second-generation" IUDs. In this article, we report on nano-Cu/low-density polyethylene composite as a potential copper carrier in IUD. Two issues for the new material are addressed: the effectiveness of polymers in reducing the initial burst in cupric ion release and the amount and pattern of continuing release. The aim of this study was to investigate copper ion release from this composite as a basis for considering its used in an IUD.
