采用蛋白质分子可形成高密度数据记录用纳米铁磁金属粉。制造这种蛋白质衍生纳米磁体的方法是 :先将蛋白质去除无定形褐铁 (ferrihydrite) ,使之成为变性铁朊蛋白质 ;然后 ,将Co与Pt离子渗入到蛋白质分子的球形腔中 ,形成纳米CoPt合金悬浮物 ;最后 ,将悬浮物在氢气中退火 ,形成 The use of protein molecules to form high-density data recording with nano-ferromagnetic metal powder. The method of making this protein-derived nanomagnet is to first remove the amorphous ferrihydrite from the protein to make it a denatured ferritin protein; then penetrate Co and Pt ions into the spherical cavity of the protein molecule to form a nano-CoPt Alloy suspension; Finally, the suspension was annealed in hydrogen to form
