The project aims at achieving single electron spin sensitivity and sub nm scale spatial resolution for a diamond spin based scanning magnetometer. To this end either custom made single crystalline diamond tips out of ultrapure diamond material of ultraclean diamond nanocrystals should be produced atomically precisely implanted and integrated into the existing AFM set-up. We intend for the first time to image single electron spins on surfaces. In addition, we will measure the magnetic field of single ferritin molecules and single spin labels on tobacco mosaic viruses. To get access to fast relaxing electrons spins we will extend our set up to low temperature operation and apply it to imaging metalloproteins. Our approach, once successful, has the potential to revolutionise magnetic field imaging in various areas of science, ranging from solid state physics to protein structure analysis.

该项目的目标是实现单电子自旋灵敏度和亚纳米尺度的空间分辨率的金刚石自旋扫描磁强计。为此，由超纯金刚石材料或超净金刚石纳米晶体定制的单晶金刚石尖端应该以原子精确地植入并集成到现有的AFM装置中。我们打算第一次在表面上成像单电子自旋。此外，我们还将测量烟草花叶病毒上单个铁蛋白分子和单个自旋标记的磁场。为了获得快速弛豫的电子自旋，我们将把我们的设置扩展到低温操作，并将其应用于成像金属蛋白。我们的方法一旦成功，就有可能彻底改变从固态物理到蛋白质结构分析等各个科学领域的磁场成像。
