They are linear molecular magnets and efficient contrast agents for magnetic resonance imaging (MRI). The term gadonanotube was introduced in 2005.〔 ==Preparation== Owing to their large magnetic moment (µ2 = 63µB2) Gd3+ ions are the most popular MRI contrast agents. They are toxic in aqueous solutions, but can be neutralized by chelation or by encapsulating them into carbon nanotubes or fullerenes, resulting in gadonanotubes and gadofullerenes. The as-prepared nanotubes have their ends capped by carbon that hinders their filling. They are cut open by a chemical or/and ultrasonic treatment, and their side walls are chemically modified (functionalized) to impart solubility in water and biological compatibility.〔 Then the nanotubes are sonicated in an aqueous solution of GdCl3 to form gadonanotubes, where the Gd3+ forms clusters of 2–5 nm diameter which contain up to 10 ions. The small size of the clusters is responsible for the superparamagnetism and superior MRI contrast properties of gadonanotubes.〔 The non-encapsulated Gd is removed by repeated washing with water.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gadonanotube」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
