The surface structure of purple membranes was imaged using an atomic force probe mounted in a scanning tunnelling microscope. One of the two different membrane surfaces showed protruding, disc-shaped features forming an hexagonal lattice with about 6 nm centre to centre spacing. These are identified as the cytoplasmic surfaces of trimers of bacteriorhodopsin molecules and are correlated with the structural information on bacteriorhodopsin obtained from numerous earlier electron microscope and diffraction studies.
使用安装在扫描隧道显微镜中的原子力探针成像紫色膜的表面结构。两种不同膜表面之一显示出突出的盘状特征，形成中心间距约为6nm的六边形晶格。这些被确定为细菌视紫红质分子三聚体的细胞质表面，并且与从许多早期电子显微镜和衍射研究中获得的细菌视紫红质的结构信息相关。
