1991年，理论物理学家约翰·赛德斯首次提出了将原子力显微技术与MRI相结合用以对微小生物结构成像的想法。
Biological material can be difficult to image in ordinary TEMs because electrons pass through it without deflecting.
普通显微镜在探测生物材料时，因为电子通过材料不偏转而不易呈像。
Usually, though, the mirror image of biological molecules are weaker or have no effect. They can't shake hands with our proteins.
