When a colloidal solution consisting of nano-sized acicular materials and bacterial cells is stimulated with sliding friction, at the interface of the hydrogel, the nano-sized acicular material and bacterial cells form a chestnut-bur shaped complex. When the sliding friction force becomes a driving force, the chestnut-bur shaped complex grows and penetrates the bacteria to form a penetration-intermediate. This phenomenon, with the formation of a penetration-intermediate, is known as the "Yoshida effect". This research demonstrated the Yoshida effect was utilized for quantitative detection method of asbestos and the occurrence of the Yoshida effect may be a driven force for prokaryote evolution during providing seismic stimulation.

当由纳米针状材料和细菌细胞组成的胶体溶液受到滑动摩擦的刺激时，在水凝胶的界面上，纳米针状材料和细菌细胞形成了栗子形的复合体。当滑动摩擦力成为驱动力时，栗子状复合体生长并穿透细菌，形成穿透中间体。这种现象，随着穿透中间体的形成，被称为“吉田效应”。本研究证明吉田效应可用于石棉的定量检测方法，吉田效应的发生可能是提供地震刺激过程中原核生物进化的驱动力。
