There is a considerable amount of work that shows the biomagnetism of organic components without ferromagnetic components at the molecular level, but it is of great challenge to cover the giant gap of biomagnetism between their experimental and theoretical results. Here we show that the diamagnetism of aromatic peptides is greatly enhanced for about 11 times by self-assembling, reaching two orders of magnitude higher than the mass susceptibility of pure water. The self-assembly of aromatic rings in the peptide molecules plays the key role in such a strong diamagnetism.

自组装芳香肽意外强磁性

有大量工作表明在分子水平上没有铁磁成分的有机成分的生物磁性，但是要覆盖其实验和理论结果之间巨大的生物磁性差距是很大的挑战。在这里，我们表明芳香肽的反磁性通过自组装大大增强了约11倍，比纯水的质量敏感性高两个数量级。肽分子中芳环的自组装在如此强的反磁性中起关键作用。
