In order to analyze the effect of surface functional groups on fungal development, the model plant pathogen Magnaporthe oryzae and several fungi known as contaminants of residential environment were cultivated on the molecular modified surfaces with various functional groups. Gold, stainless steel, glass, and silicon were used as substrate. The ‘self-assembly’ method was used for the surface modification. We discovered that some surface functional groups are involved in the regulation of infectious structure development in M. oryzae. Moreover, fungal adherence was suppressed by specific functional group. This result leads to the development of novel antimicrobial modification technique which can apply to various materials.

为了分析表面官能团对真菌发育的影响，在不同官能团的分子修饰表面上培养了模式植物病原菌稻瘟菌和几种被称为人居环境污染物的真菌。使用金、不锈钢、玻璃和硅作为衬底。采用“自组装”的方法进行表面改性。我们发现一些表面官能团参与了米曲霉侵染结构发育的调控。此外，真菌的黏附被特定的官能团抑制。这一结果导致了新型抗菌改性技术的发展，该技术可以适用于各种材料。
