趋磁细菌合成纯的形态精确的纳米磁铁矿晶体称为磁小体。掺杂磁小体改变了它们的磁性，使它们成为非常有前途的纳米材料。在此，我们提出了体内磁小体中最高的Co 2+（3.0%），Mn 2+（2.7%）和Cu 2+（15.6%）掺杂。最重要的是，第一次报告的铜掺杂在磁铁矿磁小体和最高的金属掺杂到磁小体记录。与以前的报道相比，Mn和Co掺杂记录了2倍的增加。
Magnetotactic bacteria synthesize pure morphologically precise nano-magnetite crystals called magnetosomes. Doping magnetosomes varies their magnetic properties, making them very promising nanomaterials. Here we present the highest doping of Co2+ (3.0%), Mn2+ (2.7%) and Cu2+ (15.6%) into magnetosomes in vivo. Most significantly, the first report of Cu-doping in magnetite magnetosomes and the highest metal doped into magnetosomes recorded. A 2-fold increase is recorded for Mn and Co doping over previous reports.
