放射線加工による繊維状捕集材の開発 Fibrous Metal Ion Adsorbent Synthesized by Radiation Processing

玉田 正男 Masao TAMADA

＜要旨＞Graft polymerization is a radiation processing which can impart a desired functional group into a trunk polymer. When a nonwoven fabric is selected as the trunk polymer of the graft polymerization, a fibrous metal adsorbent can be synthesized. The resulting fibrous adsorbent realizes extremely high flow rate in the metal ion adsorption. The present paper describes the characteristic of the fibrous adsorbent and the applications to removal of toxic metals and collection of useful metals. Keywords: Radiation Processing / Graft Polymerization / Fibrous Metal Adsorbent / Nonwoven Fabric / High Flow Rate / Removal of Toxic Metals / Collection of Useful Metals

医療機器とその材料の生物学的安全性と生体適合性 Evaluation of Safety and Biocompatibility of Medical Devices and Their Materials

中岡 竜介・土屋 利江 Ryusuke NAKAOKA and Toshie TSUCHIYA

＜要旨＞Before utilizing medical devices, evaluating their safety is indispensable. When polymers are utilized for the medical devices, not only themselves but also their components such as monomers, catalysts and additives must be evaluated to estimate their safety as well as their biocompatibility by appropriate methods. Various studies on cell-polymer interaction provide valuable information to develop the safety and biocompatibility of materials utilized for medical devices. Keywords: Medical Devices / Safety / Biocompatibility / Cell-Polymer Interaction / Cytotoxicity / Genotoxicity / ISO
