In order to investigate the shape and distribution of lignin in wood cell wall, atomic force microscopic observation by the use of special needle (cantilever) was examined. This needle was covered by a compound which was expected to exhibit pai-pai interaction with lignin aromatics. Tetracyanoethylene was found to have very strong interaction with lignin as expected. However, atomic force microscopic observation of lignin by the use of this needle was not successful. The amount and linkage method of this compound to the needle has to be modified.

为了研究木质素在木材细胞壁中的形态和分布，采用专用针（悬臂）进行了原子力显微镜观察。该针被一种化合物所覆盖，该化合物有望与木质素芳烃表现出成对的相互作用。结果表明，四氰乙烯与木质素具有很强的相互作用。然而，利用该针对木质素进行原子力显微观察并不成功。必须修改该化合物与针的量和连接方法。
