先用低能电子衍射（ＬＥＥＤ）证明了甘氨酸（ＮＨ２ＣＨ２ＣＯＯＨ）能在室温下在Ｃｕ单晶表面产生比较稳定的吸附，然后用扫描隧道显微镜（ＳＴＭ）进一步研究了其吸附情况，看到单个甘氨酸分子在Ｃｕ（１１１）面上吸附稳定并至少有三种吸附状态．分子操纵研究结果表明，甘氨酸分子是被针尖“推着”移动的，它在Ｃｕ（１１１）面有固定的吸附位，并且移动时其吸附状态可以不变．研究结果表明，甘氨酸适合做室温下小分子的可控操纵研究，并且也说明室温下小分子的可控操纵是可能的．
Low energy electron diffraction (LEED) was used to prove that glycine (NH2-CH2COOH) can generate stable adsorption on Cu single crystal surface at room temperature, and then the adsorption was further studied by scanning tunneling microscope (STM) A single glycine molecule is adsorbed on the Cu (111) surface and has at least three adsorbed states. The results of molecular manipulation indicated that the glycine molecule is “pushed” by the needle tip and has a fixed adsorption site on the Cu (111) surface, and its adsorption state can be unchanged when it is moved. The results show that glycine is suitable for controlled manipulation of small molecules at room temperature and also suggests that controlled manipulation of small molecules at room temperature is possible.
