摘要:

我们提出了一种新的高分辨率纳米磁共振成像(nano-MRI)的方法,结合了高自旋灵敏度的基于磁共振的磁共振检测与高光谱分辨率核磁共振(NMR)光谱。通过应用NMR脉冲设计使用最优控制理论,我们证明了一个因素$500$减少质子自旋共振线宽在$(50\text{-nm})^{\text{3}}$体积的聚苯乙烯和图像质子自旋在一维空间分辨率低于$2~\text{nm}$。

英文摘要:

We present a new method for high-resolution nanoscale magnetic resonance imaging (nano-MRI) that combines the high spin sensitivity of nanowire-based magnetic resonance detection with high spectral resolution nuclear magnetic resonance (NMR) spectroscopy. By applying NMR pulses designed using optimal control theory, we demonstrate a factor of $500$ reduction of the proton spin resonance linewidth in a $(50\text{-nm})^{\text{3}}$ volume of polystyrene and image proton spins in one dimension with a spatial resolution below $2~\text{nm}$.
